The Power Within

Near the top of the tower a pair of loud screams were heard. Natsu and Aang were seen running to Jellal. Natsu's fist was surrounded by flames which he used to punch Jellal in the face, but he managed to duck under it. Jellal later avoided a fire ball that was thrown by Aang, however this distraction gave Natsu the opening he needed. The Dragon Slayer engulfed his right leg in flames and kicked Jellal causing him to fly through the air. As he did, Natsu was punching him relentlessly this sent him to a crystal sticking out of the ground. He opened his eyes and saw three comet looking fireballs speeding towards him, they all exploded on him. Natsu stood in front of Aang before the Avatar took a deep breath and blew a huge gust of wind to Natsu, creating a Tailwind that propelled the Dragon Slayer at a much faster speed while running to Jellal.
"Fire Dragon Wing Slash!" Natsu chanted as his arms were engulfed in flames which he sent to Jellal. He managed to block it but the flames threw him off balance but as Natsu was on all fours close to Jellal, he wasn't done yet. "…and… Talons!" both his feet were covered in his flames and he quickly raised them upwards to kick Jellal forcing him to another crystal wall. Natsu was upside down while Aang stood next to him. "Fire Dragon Roar!" After Natsu puffed his cheeks, a huge burst of flames shot from his mouth to Jellal while Aang took a deep breath and created a huge stream of fire which he shot by putting his hands together. The combined fire attacks made a huge explosion where Jellal was standing.
When the flames faded on Aang and Natsu's side they maintained a serious look.
Jellal's silhouette could be seen through the flames, he moved his right arm through them as if they did little damage while also throwing off his jacket revealing himself to be wearing a tight sleeveless shirt with black fighting gloves. "Are you being serious?" He asked maintaining a smirk on his face.
"Our attacks didn't even faze him?" Aang asked in slight disbelief
"Natsu Dragneel… Child of Igneel. Avatar Aang… Last of the Airbenders." Jellal began and caused both of his opponents to flinch. The dark wizard held out his right hand. "I wanted to know what it is like to fight the both of you before I destroyed you, but this is nothing to fear at all."
"Say what!?" Natsu yelled. He sprinted over to Jellal.
"Natsu wait!" Aang exclaimed.
"How dare you interrupt the ceremony?" Jellal began as his right eye was now showing the symbol of Zeref. "I will use my Heavenly Body magic to tear you to shreds!" "Meteor!" His body was surrounded by a bright yellow outline which made him avoid Natsu's attack. Once he was out of the Dragon Slayer's sight he charged into his back, head first while lying back.
After the hit Natsu turned around to face Jellal but he was faced a kick to the face before Jellal followed with a punch and a kick while flying through the air and disappearing from Natsu's sight, Natsu fell to his knees looking at Jellal flying around using his Meteor. "Damn he's too fast!" but as he said that, he saw Aang kick Jellal while he was in the air however, he grabbed Aang's leg after the kick before throwing him to a crystal tower which collapsed on impact. Jellal charged to where Aang was and saw he was gone.
"Huh? Where did he…" he sensed Aang's presence behind him. Jellal turned to fight Aang but an airball made contact with his stomach which sent Jellal flying back, but he flipped into a position where he could kick off the crystal wall with both his legs, once he did he threw a hard punch to Aang which sent him sliding across the ground. "So your airbending allows you to keep up with me? I like your technique Aang, however…" he quickly disappeared from Aang's sight, but Aang sensed he was behind him and forced himself to the ground to avoid Jellal's melee attack and shot powerful streams of fire from his hands to hit Jellal in his surprised state but he was shocked when he saw that Jellal was gone. "Looking for me?" Jella kicked Aang like a football which made the Avatar grind across the crystal floor and slammed into another wall.
Aang had a shocked expression while he was on the ground. "Impossible, he's even faster than me, but how? Can he somehow predict my movements?"
"Aang!" Natsu worriedly yelled.
"I'm okay, but we have to read his movements, but that won't be easy since he isn't touching the ground."
"I'll just use my other senses to find him!" Natsu said. He quickly caught a glimpse of Jellal's direction and ignited his right fist but was shocked when he missed.
"Your attacks will never hit me ever again!" Jellal said to the both of them before releasing a barrage of attacks that were doing damage to both Natsu and Aang that made them scream out in pain. After one more impact to them, both of them lost the pupils in their eyes as they slowly flew back. 
"This is the end. I will show you true destructive magic." Jellal flew high into the air. He formed the peace sign on his right hand and placed it on his left palm. "Be judged under the seven stars!" Seven bright yellow seals are formed, they fly under him while he was flying high up. "Seven Star Blades! Grand Chariot!" The seals now connected to each other with electric bolts forming what looks like a constellation. He blasted the attack which consisted of seven streams of light shot from each seal falling towards Natsu and Aang. After it quickly formed the same constellation on the ground, the attack created a tremendous explosion that could be seen from way outside the tower. After the attack Natsu and Aang who now had several tears in his shirt free fall through the air and slammed into the ground. Jellal landed several meters from his opponents. "That is a spell that destroys with the power of falling meteors." Jellal said as he explained the destructive power of his magic. "I'm impressed your bodies are still intact. Perhaps I went a bit over board. It would be dangerous to damage the R-System any further. The magical power is starting to leak out. I must hurry." He said looking to the unconscious body of Erza. "Isn't that right, Erza." He walked to her while kicking a piece of the R-System which was pebble sized. He turned around to Natsu, weakly throwing pebbles at Jellal. Aang who was thought to be unconscious clenched his fist while gathering up the dust around him.
Natsu began chuckling. "That attack hit… So breaking tower, or um, lacrima… That's bad, huh?" Jellal had a shocked face when he realized this. "Rotten luck for you!" Natsu punched the ground hard which sent many cracks around the floor.
"Don't!" Jellal yelled.
Aang slowly got to his knees as well. "I just realized something, something that I should have figured out a long time ago, back then while you were using your Meteor… I could feel your moments through the floor of this thing… That means…" Aang balled his right hand into a fist. "I can do… THIS!" He punched the ground with all his might and send an earth wave which Jellal avoided but the earth wave exploded on a huge mass of the Lacrima. "From what I understand, Lacrima is a crystal, and I can bend crystal." Aang fully stood up. "We just figured out your weakness!"
Natsu stood up afterwards. "Breaking things just happens to be Fairy Tail wizards' specialty. Natsu engulfs his right hand in a huge ball of fire. "I'm fired up! More than I've ever been!"
"It's over Jellal! You can't win!" Aang yelled as air spun around him in a similar fashion to a small tornado.
Jellal had a shocked expression on his face that was mixed with rage as he was surrounded in a bright yellow outline. "You little brats!" He got in a fighting stance while staring down Aang and Natsu.
…
Meanwhile out in the sea. The others were on top of Appa looking at the tower. "I wonder if Natsu and the others are alright." Lucy asked.
"They'll be alright. They are Fairy Tail wizards." Happy reminded.
"Plus, Twinkle Toes is powerful, and Flame Brain well he's destructive as all hell. They are totally getting out of there alive, and they'll save Erza too." Toph confidently said.
…
Thunder was heard clapping in the sky as the top of the tower came into view. "You stupid brats! I'll send you to Hell regretting the fact that you ever stood up again!" Jellal yelled.
Natsu chuckled. "One thing I know is that I can be really stubborn." Natsu gave a smirk.
"I'll make sure you pay for everything you have done Jellal!" Aang threatened
Jellal quickly outstretched his left hand and held it with his right arm. He shot balls of bright yellow light with tails towards both Natsu and Aang.
Both of them were able to dodge some of them and when three were speeding to Aang, he spun and shot three powerful streams of fire that blocked the beams of light from hitting him. Jellal saw the flames speed to him and they created an explosion after they hit. Natsu jumped high into the air to cause a huge impact to Jellal. "Bring it!" Natsu yelled as he fell towards his target, but Jellal countered by blasting an electric energy which engulfed the Dragon Slayer but he landed on his feet as the dug along the floor. When he stopped Jellal shot another huge ball of bright yellow energy to Natsu. Aang stepped in front of Natsu and made a huge wall rise from the floor that was made from the same Lacrima the energy blast burst through the wall and engulfed both of them as it was pushing them away from Jellal.
Erza slowly regained consciousness and saw what was happening. Both Aang and Natsu were trying to stop the blast that was already pushing them back. "Natsu! Aang!" Erza worriedly yelled. Natsu increased his strength and made the energy beam explode in front of them without causing harm. Jellal was surprised.
"What's wrong? Is that all you got?!" Natsu asked. "You're scared of breakin' the tower, so you're holding back. That ain't gonna work on me bub!" Natsu yelled as he started running towards Jellal.
"You ain't gonna talk so big for long, you brat!" he outstretched his left palm and shot a bright yellow energy beam at Natsu which sent him flying. What he didn't see was Aang speeding towards him and his fist was engulfed in the crystalline substance surrounding the tower. He performed a battle cry to let Jellal know he was coming. "You're not as powerful as you think you are, kid!" Jellal angrily said. "Meteor!" He surrounded himself in the yellow outline and Aang's attack missed. He quickly felt the air Jellal was producing when he appeared behind him. Aang raised a wall from the floor to block Jellal's kick but it only shattered past it and his eyes widened.
"Stop this!" Aang jumped back and threw his fists forwards, causing columns of the R-System to speed towards Jellal, instinctively he avoided the columns allowing Aang to get close. He simply blew a colossal gust of wind in his face which made Jellal slide back a little, but Jellal blasted a bright beam of light at Aang which forced him to slam into the other side of the tower ceiling.
Jellal saw Natsu running to him and prepared to take the attack. Natsu jumped high into the air and generated a huge fireball above his head. "Fire Dragon's Dazzling Blaze!" he threw the fireball into floor in front of Jellal. When unguarded himself from the attack he saw that the flames didn't hit him, but rather they hit the tower. He saw many pieces of Lacrima getting burned up. He was shocked and to make matters worse he saw Aang flying high up into the air with air scooters on his feet, he let himself fall to the ground close to Jellal and made a huge crater when he hit the surface, all the Lacrima shards forced into the air by the impact were destroyed when Aang made a blazing arcs in all directions that incinerated them.
"They are both… the tower!" Erza quickly realized their plan.
Natsu and Aang landed on opposite sides of Jellal. 
"The tower!" He began as Jellal clenched his fist, a vein could be seen on his neck. "The tower I spent 8 years constructing… How dare you!" Natsu was panting while Aang glared at Jellal.
"I should be asking you the same question?"
"What was that?" He angrily asked.
"You're going through this much effort to bring back someone who is the destroyer of all life? No matter what it takes, I won't let you toy with people's lives anymore!" Aang yelled with a determined face.
"Why you!" Jellal sped over to. Aang closed his eyes and he used his seismic sense to determine Jellal's next move. He performed a smirk that only Toph would normally do, he forced three twisted columns of the R-System onto the side of Jellal which made him fly through the air. He quickly opened his eyes and glared at Aang with a furious expression as he activated his Meteor. "AVATAR AANG!" Jellal screamed in frustration as he sped towards the Avatar.
"JELLAL!" Aang screamed in a similar manner he made crystals from the R-System surround his body, once he did that he jumped high into the air and engulfed his right fist in flames his arm was surrounded by crystal so his arm wouldn't get burned.
Both forces slammed their fists together in the air Aang's crystal shattered and the flames around his arm fizzled out Jellal threw a hard punch to Aang which sent him speeding back to the ground, next to where Natsu was standing. Natsu helped Aang to his feet. "Hey Aang, are you alright?" he asked.
"I'm fine, my body is screaming out in pain… but I can't give up." He saw Jellal land on the ground and Aang vision quickly shifted to Fire Lord Ozai. "Never again!" he growled.
"You two…" Jellal began.
"No matter what you do, me and Aang will keep fighting till the very end, or until we destroy this tower." Natsu said with a smirk. "I warned you that my specialty is destroying stuff." Both he and Aang were struggling to maintain a defensive stance.
"Natsu… Aang... They can both barely stand…" she worriedly thought.
"YOU WONT GET AWAY WITH IT!" Jellal screamed in absolute rage. He crossed his arms and raised his crossed hands over his head and a bright yellow seal quickly formed. This made a huge shock wave which Aang and Natsu were struggling to stand against.
Erza was struggling to keep the headwind from blowing her away but when she looked up she had a terrified expression.
"What's with this magical power? It's making me sick…" Natsu said.
Aang dug hands into the Lacrima to prevent himself from being blown away. "Natsu! Hang on!"
Erza observed something odd. "The shadows are extending backwards to the light souce!?" it quickly dawned on her what Jellal was doing. "Oh no! This magic is…"
"Both of you! Fall into infinite darkness!" soon an orb of darkness formed high above him.
"JELLAL!" Erza got to her feet and stepped in front of Natsu and Aang. 
"Would you let me be killed as well?" Jellal hesitated for a second when he saw Erza was shielding them. The attack subsided. "You need a body to resurrect Zeref, correct?"
"Yes it is a general requirement that the body be of a wizard, about as powerful as one of the Ten Wizard Saints." Jellal replied in a calmer tone.
"Erza! What are you doing!?" Aang yelled.
"But at this point it, it doesn't have to be you anymore. Die together! All of you!" The attack resumed and the ball of darkness grew and continued to suck in so much air.
"Erza move!" Natsu said.
"We can't let you… not after we came to save you!" Aang sternly said trying to get Erza to move.
"You have nothing to fear." She began with a smirk. "I will protect you, both of you."
"ERZA NO!" Aang screamed.
Jellal was finally prepared to unleash his attack. "Heavenly Body Magic: Altairis!" He threw the ball of darkness towards the three. The dark ball slid across the tower floor as it sped to Erza.
"ERZA!" Natsu and Aang cried. Erza braced herself for the attack but before it could hit her. A shadowy figure steps in front of the attack with his arms outstretched. Everyone was shocked at what happened. The figure revealed grit his teeth before a tremendous explosion rocked the top of the tower.
…
The explosion could be seen from Appa. 
"It exploded!" Happy exclaimed.
"They're okay… right?" Lucy said.
"No, this isn't happening…" Katara began.
Sho felt a pain in his chest. 
"Sho, what's wrong?" Millianna asked.
"You don't look too good." Zuko commented.
"What is this unsettled feeling I have…?" Sho said to himself.
…
The smoke cleared on the tower. Once it did, Simon with his arms outstretched in both directions stood with a furious expression and the top part of his clothes had been destroyed leaving only the metal chin, and the fabric wrapped around his head, he was revealed to have dark hair.
Aang was the first to comment on what happened. "No… you're…"
Erza began to flashback to when Rob had protected her from an attack before he died right in front of her eyes. She recognized that Simon was in the exact same position. "Simon…"
"E-Erza…" He muttered before he collapsed onto his back.
"Simon!" Erza cried. She ran to his side after he fell.
"Still crawling around here? You worm." Jellal commented.
"But, why?" Erza asked looking down to Simon. "Simon!"
Simon in his extremely weakened stated managed to smile. "I'm glad… that I… could be… of help… to you… at last…" He began coughing.
"I understand! Now, no more talking."
"You were… always… so kind…" He struggled as it was apparent he was now getting short of breath.
Erza looked over him with a very worried face. "Simon…" As he continued breathing he looked over and saw a younger version of Erza who was smiling at him. This brought a smile to his face, however Erza was screaming his name out in reality. He soon closed his eyes.
"I've… always… loved… you…" those were his last thoughts and he now lay motionless on the ground. Erza with her hands on his chest hoped that he was still alive.
Natsu had a shocked expression while Aang shared the same look. Tears were flowing from Erza's face over Simon's lifeless body.
It was then Ryu entered the section of the tower they were in.
"Hey get up, dude. Simon! Simon! SIMON!" He yelled. 
"Damn you Jellal!" Ryu exclaimed, enraged over his old friend's death. 
He shot a angry look at the Heavenly Body Wizard. 
"NOOOO!" Erza cried before she broke down into tears.
A chuckle was heard and it was from Jellal before it broke into laughter. 
"How pointless! How incredibly pointless! They call that throwing away your life, Simon!" He said while still looking amused. "This doesn't change anything. Because there's is no way anyone is leaving this tower alive!"
"Shut up." They all heard. They all saw Aang who was now engulfed in an air sphere and his tattoos were shining a bright white color. "A person dying… IS FUNNY TO YOU!?" Aang furiously said in a mixture between his voice and all the other past Avatars. "You will pay! Jellal!" He blasted an extremely powerful blast of air at Jellal which forced him to a Lacrima wall. This shocked him as he looked at Aang.
"This can't be…" Erza began.
"The Avatar State!?" Natsu thought.
Aang inside his air sphere hovered up high into the air once this happened he shot flames from his fists, his mouth and also his feet which destroyed the shoes he was wearing. The body of flames danced in the air and began to compress, they circled around the air sphere. From below the sea boulders were flying out, they surrounded Aang from a far distance. The Avatar clenched his fists which forcefully compressed the rocks to a smaller size. They surrounded his air sphere just like the flames were but in a way where they wouldn't touch them. A huge burst of water shot out from the ocean below and the huge mass of water surrounded Aang before he managed to compress it into a ring of water that penetrated the air sphere and was surrounding his body.
…
From Appa, everyone could see what was happening. They could feel the raging winds from there.
"What's happening!?" Happy asked.
"It's Aang. He's alive…" Katara said.
"But… something is wrong…" Lucy quickly figured.
"Yeah." Katara agreed. "Something forced him into the Avatar State!"
Sokka began celebrating. "Oh yeah! Watch how Aang is going to kick some serious butt!"
"So cool." Millianna happily said.
"So this is the Avatar State..." Lucy said in awe.
"What do we do?" Zuko asked.
"There is nothing we can do." Katara said. "Aang is at his most powerful, but he is also very dangerous, he still hasn't gained full control of it."
"He looks pretty dandy to me." Wally said.
"I just hope Aang doesn't do more harm than good." A tear shed from Katara's eyes.
Happy walked over to the water tribe girl. "It will be alright! We have to believe in them, we will get out of this and they will be coming home with us!" Happy declared.
"You're right…If Jellal triggered it, then Aang will go for him and destroy the tower in the process. I just hope that he will be alright."
"He will be!" The cat confidently said. "I know it."
…
Meanwhile above the tower. Aang in his elemental sphere hovered above the Tower of Heaven. He angry face turned to Jellal.
He looked up at the Avatar. "So, that is it. The Avatar State!" Aang in his elemental sphere charged flew towards Jellal to collide with him. He clashed with him and this sent both of them through the many crystals on the roof both of them were floating in the air behind the tower, Jellal was by the Tower while Aang was flying a small distance away from it. "Bastard!" Jellal angrily yelled. He used his Meteor and flew above Aang, he proceeded to shoot a huge beam of light towards him. The Avatar countered and sent three huge comet shaped balls of fire to counter the beam. Through the smoke a small mass of water was speeding to his wrist. When it hit, his whole body flew back with the same momentum.
Jellal found his body was attached to the tower because the water on his wrist had frozen solid. Jellal used his free right hand to try and break it but his right hand was now frozen over his left hand as Aang shot another mass of water that wrapped around both arms and froze them in place. When Jellal was stuck he saw the that the orbiting rocks had stopped, Aang thrust his arms forwards and crossed them, this caused the individual pieces of two rocks in front of him break off and fire to Jellal's body in a similar fashion to a minigun. After Jellal's body was pounded with the bullet-like projectiles he flew up high. "I'll kill you!" He yelled. He performed a gesture with both hands which made a magical seal appear and this made seven seals appear above him. When the formed the constellation, Jellal smirked. "Goodbye, Avatar! Grand Chariot!" the seal each shot a powerful beam of light that focused on Aang.
Showing no fear he shot three tendrils of water and three streams of fire to counter Jellal's Grand Chariot but when there were still beams speeding to him he quickly avoided them while in his elemental sphere. When he got close to Jellal the mage disappeared from his sight. Aang couldn't sense his presence in time and he was punched back to the roof of the tower. An explosion was made when he hit the ground, this destroyed his elemental sphere.
Jellal landed on the tower and saw Aang get back to his feet but still in the Avatar State. "Where is that magic that you can use, Aang? Don't tell me it was just a one-time fluke." Aang punched both his fists into the lacrima, the crystals grew out and surrounded the top of his arms, when he pulled them out he sped over to Jellal and decreased his wind resistance, so much so that Jellal couldn't see him coming. He slashed Jellal several times with the lacrima that was attached to his arms. He cross slashed through Jellal and once he slid a distance from him they shattered. Aang turned around and shot a glare at Jellal. His fist was clenched and somehow flames surrounded them and Aang felt no pain. "No… It can't be…" Aang sprinted to Jellal.
"Fire Dragon's Iron Fist!" he exclaimed punching Jellal in the face. Erza and Natsu who saw this were shocked as Aang managed to use Fire Dragon Slayer magic. When Jellal stepped back he saw Aang was in the air. He saw him with his regular flames in right arm and the flames from his Dragon Slayer magic in the other. They each made a growing mass of fire that Aang put together by slamming his hands together and the mixture of flames grew and he raised it over his head.
"He's mixing his Firebending flames with the Flames from his Dragon Slayer magic?" Erza thought.
Jellal looked at the colossal bright ball of fire that Aang was going to use on him. "Fire Dragon Power Blaze!" He threw the huge fireball on top of Jellal which made a huge explosion and made flames tower into the air which was able to be seen from outside the tower. Aang landed on the ground looked into the huge boulder and saw that Jellal was gone as he used his Meteor to avoid it. He angrily looked behind him and Jellal punched him in the face, both Natsu and Erza were shocked as to how Jellal avoided the huge attack. Aang slid across the floor while making craters in the floor. He crashed into a huge crystal shard which collapsed on him and covered him in debris.
"Aang!" Erza cried.
"So much for the protector of life." Jellal said with a smirk, he was then shocked to see Natsu with a piece of the Lacrima in his hand, he was actually taking bites from it "That bastard. He is eating the R-System!" As he continued to consume the Lacrima he was now becoming engulfed in bright blue energy. When the energy was gone he slammed his fists into the ground this force a wave a light blue energy to Jellal, he managed to avoid it, after that Natsu began coughing out the liquefied Lacrima he ate and he was holding his throat as it looked like it was killing him, he began to roll on the ground.
"That's insane!" Erza yelled. "Ethernano is fused with other elements other than fire, you know!"
Natsu was screaming while holding his throat, veins were etched on his hand and his face.
Jellal was now slightly confused. "Did you seriously think you can power up by eating magic energy instead of flames? That kind of pea-brained thinking will lead to your own downfall!"
As Natsu was screaming, huge flames engulfed him while his eyes shone bright red, soon a fiery figure of a dragon appeared behind him. He was standing with his arms relaxed and his legs bent while his eyes still had the bright red glow, his clothes were floating upwards on his body as a result of the raging flames around him. Suddenly scales began growing on Natsu's face, his eyes returned to normal as the flames continued to rage.
"He's actually absorbing Etherion!?" Jellal thought.
Natsu's sped to Jellal and threw his knee to his chest while the flames followed him. "You're the reason…!" he sped to Jellal and grabbed him by the throat and was forcing him through floor and through the many floors of the R-System. "Erza is crying!"
Meanwhile in the floor that Aang had passed out on, he was out of the Avatar state and was unconscious, in his sleep state he remembered when he was talking with Erza before. He remembered when Erza wasn't acting normal and he when remembering when Erza pulled him into a hug, he quickly remembered what she said earlier. "You overestimate me, Aang. There are some things that even I am afraid of." The crystals that fell on him began to shine a bright color. They quickly shattered into small pieces and Aang yelled out and a tornado of air surrounded him as he screamed. He saw Erza lying on her knees.
"Erza…" Aang said in his Avatar State voice. He saw the hole that Natsu charged Jellal through.
"I made a promise!" Natsu yelled as still pushed Jellal through several floors. Natsu remembered Simon telling both him and Aang to take care of Erza. "I made a promise!" Natsu repeated.
"You cocky bastard! Meteor!" he flew up and away from Natsu as the Dragon Slayer fell through the tower but he managed to stop himself. "You'll never be able to catch me at this speed! What!?" As he flew up he saw Aang speeding down to him in his air sphere. An orange-red magical seal engulfed his hands that were locked by his fingers, he slammed his connected hands which here covered in flames on top of Jellal's which forced him back down, spinning to where Natsu was running up to catch him and when the Dragon Slayer caught up to Jellal, he gave a huge punch to his gut which forced both of to the ceiling of the roof. Aang saw this while standing on a crystal shard below. He covered himself in a sphere of air and chased the two.
Meanwhile on the ceiling Erza saw Natsu and Jellal speeding from through a hole. "Impossible! I can't lose!" Jellal declared, he recovered from the punch and spun in the air to kick Natsu to a high crystal shard. Jellal seeing his opportunity jumped from a crystal so he could be high in the air above Natsu. "I'm making a kingdom of freedom!" Before he could get to Natsu he saw Aang speeding towards him as he shot flames out of his feet using the flames as afterburners.
He surrounded himself in flames before curving blades of air formed in front of the flames. "Fire Dragon Wind Edge!" He collided with Jellal sending him flying further into the air. Jellal grabbed Aang by his stomach and threw him to a crystal that was opposite Natsu.
"Zeref whispered to me in my pain and fear!" Jellal yelled as he flew towards Aang "'Do you desire true freedom?' Zeref beckoned… That's right! Only I can sense Zeref! I am the chosen one! Zeref and I will create a truly free kingdom together!" He collided into the crystal Aang was leaning on and he missed and saw that Aang was above him. The Avatar quickly magnetized pieces of crystal to his hand and punched Jellal towards Natsu.
Natsu began running towards Jellal from the ground after hearing everything he said. "And you'll make it by taking away other people's freedom!"
Jellal managed to control himself in the air and began firing bright yellow energy projections from his hands. "Only the ones with the will change the world can make history!" Natsu managed to get to a crystal after dodging all the energy beams as he saw Aang was going to punch Jellal with a fiery fist, but he saw this coming and grabbed the Avatar's wrist and threw him to the ground, not far from where Natsu is. "Why can't you both understand this!?"
Jellal made several movements with his hands and a huge bronze magical seal appeared. Natsu gasped while Erza knew what Jellal was planning.
"Abyss Break!?" Erza gasped. "You fiend! You plan to destroy the tower as well!?" 
"8 more years… No…this time I'll finish it in 5." Jellal replied. "Zeref wait for me!" suddenly a magenta like swipe was seen going through his stomach as the background around him turned black. This was a wound that was given to him by Erza in their earlier battle. The Abyss Break seal disappeared and he free-fell to the ground. 
"End of the line, bastard. I'm going to make you pay for killing Simon!" Ryu yelled, propelling himself towards Jellal. "DRAGON FIST!" 
He punched Jellal as hard as he could. 
"The freedom you desire is flawed!" Aang bellowed out.
"You will never find freedom!" Natsu yelled. "There is no such thing as freedom for somebody taken over by ghosts."
"Before you can declare freedom for everyone else…" Aang yelled. When he says this he makes huge streams of fire, large whips of water, large flurry of rocks, and huge waves of air combine and whirl around him.
Soon huge flames formed a dragon around Natsu and Aang and the fire dragon was surrounded by the swirling of the four elements.
Erza looked up and saw what was going on she saw the attack Natsu and Aang were preparing. Her eyes were wide open. "Is that…"
Jellal saw the attack forming in front of him. "NO! It can't be!"
"A UNISON RAID?!" Both Erza and Jellal exclaimed.
"FREE YOURSELF FIRST, JELLAL!" They both exclaimed Jellal saw the dragon combined with the four elements speeding to him. "AVATAR DRAGON'S ELEMENTAL INFERNO!" Natsu connected a hard punch to Jellal's face while Aang threw a punch to his stomach. The screams of all three of them were heard as a colossal white energy engulfed the three of them. A dragon roar was heard after they had punched Jellal. The impact of him slamming into the tower created exploding shock waves throughout the tower. A huge dust cloud formed at the bottom of the tower.
…
Appa was slightly struggling to stay in the air after Jellal's impact. 
"What happened?" Wally asked.
"What is going on over there?" Zuko asked.
"It has to be Natsu and Aang." Happy said.
"Yes I agree." Lucy said.
"But is it going to be okay?" Millianna asked.
"It'll be okay… Or so I'd like to think." Gray replied. "But they sure are going wild there…"
Jellal was defeated and knocked out on the ground. Natsu and Aang fell to the ground after giving the final blow to Jellal. When they hit the ground they made a small crater with their feet.
Erza was shocked at both the power of Natsu and Aang. "Natsu… Aang… This is their true power… A Dragon Slayer… The Avatar… their powers are extraordinary…" Erza thought as she looked at the serious faces of both Natsu and Aang as they were still in their Dragon Force and the Avatar State respectively. They were looking away from Erza. "They even defeated Jellal." Natsu turned around and smiled at Erza. Aang's eyes returned to normal, he turned to face Erza as well and gave a smile too. "The battle I've been fighting for these past 8 years is finally over." Erza was smiling back at them. Moments later Natsu fell to his knees while Aang was falling to his side. "Natsu! Aang!" Erza rushes to them, catches them and stops them from hitting the ground. She brings them close and hugs them. Natsu's scales disappeared and Aang's airbender tattoos stopped shining white and faded to their sky blue colour.
"You're both really incredible…" Erza praised while hugging them. Soon the tower began vibrate and bright beams of light were seen coming from the tower.
…
From Appa the bright pillars of light were seen. "Nya! How pretty." Millianna said.
"Y-yeah sure, can I have my arm back?" Zuko asked as Millianna had hooked her right arm around Zuko's left arm and he tried to get her off him.
"No that's not good." Wally said.
"I feel a terrible magical power coming from that light!" Lucy said.
"Then that means… Is Etherion going out of control?" Grey asked.
"Out of control! What do you mean!?" Katara exclaimed.
"The magical power of Etherion." Sho said.
"Keeping that great amount of magical power in one place can never be stable for long." Happy explained.
Juvia began to explain the situation too. "A turbulent vortex of magical power with nowhere else to go will burst out, causing a huge explosion."
Wally was scared as she stood by Millianna and Sho. "Woah! We'll be caught in it as well!"
"What about sister and the others! They are still inside!" Sho exclaimed.
Grey gave a huge glare at the scene. Toph clenched her first as her head turned to the location of the Tower of Heaven "This isn't about who's saving who anymore!" Grey exclaimed. "We're all going to be wiped out together!"
"Not if I have anything to say about it!" Sokka declared. "I'm getting us out of here!" Sokka yelled. He pulled on Appa's reins and flew made him fly from the exploding tower.
…
Meanwhile on the tower Erza was carrying both Natsu and Aang by putting their arms over her shoulders but she was moving too slowly and the tower was exploding around her. She saw Simon's body sliding into the many cracks that were on the falling tower, when she saw it slide she quickly looked away and resisted the urge to cry. She quickly jumped from crack to crack to find a way off the tower. She was avoiding pillars of light that were emerging from the floor of the tower. One of the pillars of light threw her off her balance causing her to fall, dropping her friends behind her.
A bubble had formed in front of her as Erza looked behind her with an angry expression. "Magical power strong enough to deform the container… The Lacrima… That's even more destructive power than I had ever imagined. Even if we get outside, we'll be caught in the explosion." "Damn!" she cursed while punching the floor. "Is this the end?" she looked to Natsu's unconscious form before turning to Aang who was also unable to move due to unconsciousness too. "No… There's no way I'll give up. Now it's my turn to save the both you." An explosion behind her quickly interrupted her thoughts. "But it's impossible to hold it back. What can I do?" she had a flashback to when Jellal had her restricted with his Bind Snake, she remembered that Jellal told her that the power that the Lacrima holds will be used to reconstitute her body into Zeref's. Erza looked to a large piece of the R-System that was still intact and saw her own reflection. "If I can fuse with Etherion, then I can control this power? Can I stop the explosion?" she wondered. She placed her palm on the bubble that appeared in front her earlier.
Once she placed and pressed hard, her palm penetrated the bubble, the contents of it made her yell in pain. "Good. The Lacrima is still accepting me." Natsu started to wake up, he saw Erza's arm reaching into the Lacrima. He got to his feet and looked at her in concern.
"Erza…"
She looked back to see Natsu looking at her. Erza was also unaware that Aang was awake too only he was on his knees. "W-what are you doing?" Aang asked making his presence known.
"Erza… you're putting yourself into the Lacrima?" Natsu said.
"This is the only way to stop Etherion."
"Stop Etherion?"
"I'm confused. Didn't Etherion fire already?" Aang said, scratching his head
"The blast was absorbed by the Lacrima." Erza quickly explained. "Look around you. This tower will shortly explode as Etherion goes out of control." Natsu and Aang had shocked looks on their faces. "But if I can fuse with Etherion and suppress it…"
Natsu quickly got up. "What are you saying you idiot!?"
"If you do that then you'll… you know what's going to happen!" Aang exclaimed getting up on one leg. Erza gave a scream that indicated she was in deep pain. Natsu tried running to her but he fell to his stomach after realizing he didn't have the energy.
"Crap… I can't… move…" Aang cursed as he tried to get up and stop Erza from her crazy plan.
"Don't worry about it anymore. I'll stop it for sure!"
"Don't!" Natsu screamed.
"It shouldn't end… like this." Aang placed his palm on the ground and managed to use the crystal to make a pillar that would launch him closer to Erza while Natsu crawled with all his strength.
Erza looked at both of them as most of her body was inside the Lacrima. "Natsu, Aang… I couldn't have lived without Fairy Tail. A world without my friends is unthinkable. You are all that important to me." The Lacrima began to cover her and it was reaching her face. "I don't care, as long as I can save everybody, even if it costs me this body. So be it!" he entire body was now inside the Lacrima.
Aang's expression quickly turned to fear both he and Natsu began banging on the Lacrima. Aang punched the Lacrima but his fist just wouldn't go through.
"Erza! Get out of there!" Natsu yelled.
Aang saw a small puddle of water. He brought it to him and made it slash across the Lacrima so that it might slash through it. "We're not going to let it end like this! Erza!" Aang exclaimed as he moved the mass of water sharpening the ends to try and cut the Lacrima. This however was proving very ineffective.
Erza was floating backwards in the Lacrima. "Aang, Natsu, take care of everyone for me. Because I will always be by your side."
Natsu had tears building up on his eyes and Aang looked at the Lacrima in disbelief. "ERZA!" they both screamed as an explosion centered around the Lacrima Erza was in engulfed them.
…
Sokka was trying to fly Appa from the tower while it began to give of a bright blue glow.
"It's exploding!" Wally yelled as everyone was bracing themselves. Millianna held onto Zuko. Katara and Lucy held onto each other, Toph held the side with all of her might. They would feel wind shockwaves rocking them.
"No, it's not!" Gray noticed. "Etherion is heading up into the sky!" A bright blue light was blasting into the night sky.
"What does that mean!?" Toph yelled.
"Are we safe?" Sokka asked.
They saw the beam stop and soon huge waves began to rage around from where the tower was. Winds were blowing so hard that they slightly pushed Appa off balance making him roar in discomfort. Momo was about to fall but Happy caught him. "I gotcha!" Happy cheered.
Elsewhere Fukuro was carrying both Ikaruga and Vidaldus away from the tower using his rocket boosters.
The boat that Chun and Ping were in was still far from shore. Ping saw a huge wave speeding towards them. "You've got to be kidding me!" Ping yelled.
"No! Not today!" Chun yelled as the wave crashed into their boat. The wave had knocked Ping unconscious and she was falling into the water, but a pair of arms pulled her up to the surface. "Oh no. You're not getting out of this that easy!" Chun said while trying to keep above water and saw their boat was nowhere to be found.
On Appa, everyone noticed something odd. "It disappeared!" Happy yelled.
"Etherion went into the sky!" Gray said.
Katara, Lucy and Happy were looking up in disbelief and screamed the names of their companions and in order.
"AANG!"
"ERZA!"
"NATSU!"
They all looked at the place where the tower once stood, as it was now completely gone.
----(Flashback Begins)
Erza who escaped from the Tower of Heaven had washed up on Fiore's short a few hours ago was passed out on the beach. While Erza was unconscious a woman who wore a maroon cloak over her head, she noticed the bruised body of Erza on the sand. The woman kneeled to Erza and examined her and noticed the patch on her right eye. 
"What happened to you?" the woman asked. She pulled off her hood. This revealed her long dark brown hair, her light skin, and gold coloured eyes. She picked up Erza and proceeded to walk off the beach to a small house that wasn't far from it.
…
Hours past and Erza quickly arose to the smell of food, it had been a very long while since she had eaten anything, and she quickly noticed that she appeared to be inside a room. It looked very plain; with wooden cabin like walls one window had let sunlight into the room. She looked at her wrists and saw that her disabled prison cuffs were off her. She found herself under the covers of a bed when she got up she saw a mirror. In her reflection she saw the clothes she was wearing in the prison were gone and replaced with a pinkish red dress, the patch was still over her right eye. Footsteps were heard, Erza looked at the figure. She wore a sleeveless red fabric with a similar fabric used for her pants, she had sandals. Her dark hair was quite long and she had a top-knot that was tied with a black band. 
"You're awake. I'm glad." The woman said. Erza slightly stepped back in fear. "You don't need to be scared. I am not going to hurt you." The woman said in a soothing voice. 
…
Later they both were sitting at a dining room table and in front of them was a plate that had a piece of meat on it with an assortment of small vegetables and a spherical roll. "Go on, eat. You must be hungry." Erza's stomach betrayed her intention because it let out an audible grown which made Erza blush slightly, the older woman gave a slight giggle. "You never told me your name. Please I would like to know." 
Erza was slightly hesitant considering that she had just gone through. "E-Erza." She revealed.
"Erza? That sounds like a nice name. It almost sounds like my name. My name is Ursa." The woman revealed. "That's kind of funny, our names sound alike." Ursa said with a smile.
"Ursa?" Erza repeated. 
…
Ursa and Erza had spent an extended amount of time together and Erza lived with Ursa for a while since she had no other place to go. Ursa mentioned she had a husband but he had to work for most of the day so they could afford the house they lived in. Erza had opened up more to Ursa but still didn't want to explain the reason for why she cried for some nights after Ursa had put her to sleep.
Erza felt more comfortable around Ursa that she told her what happened to her eye and also about what she had to go through in the Tower of Heaven, when she got to mentioning Jellal, she wasn't able to explain fully as she broke down prompting Ursa to comfort her.
About two days later Erza came across one of Ursa's old robes. A robe which had a flame insignia on it. Erza being curious decided to bring it up. 
"What is this? I've never seen you wear it before." She asked.
"That's from a time which I wish to forget, but I know I shouldn't. It would be wrong of me." Ursa replied.
"What do you mean?"
"My husband and I aren't from here. We actually traveled a long way from home to get here, but I regret leaving my children behind."
"Your children?"
"I had two children their names are Zuko and Azula. My son Zuko, was kind hearted boy, you actually kind of remind me of him, Erza. My eldest daughter, Azula… she was... special, she was a gifted child, but she was mean to others though, but she is still my daughter and I care about her. I fear that I left both of them in the wrong hands."
"Where are they?"
"Far away, far from where I could see them again." Erza could feel a hint of sadness from the older woman.
…
The next day Ursa took Erza to a popular wizard's guild in Magnolia. "Fairy Tail?" Erza asked.
"I heard there are nice people here. I know that they will take good care of you." Erza didn't say anything as she looked at the building, when she saw the symbol of the guild itself, she remembered seeing the same symbol on Rob while he protected her from the blast that took his life. "Something wrong, Erza?" Ursa asked. The little girl shook her head to let Ursa know she was okay. The older woman watched as Erza walked into the guild.
…
A few days later, Erza who was now dressed in a white shirt with a blue dress was around Ursa, Makarov and Porlyusica. The latter was examining Erza's right eye.
"That's quite a horrid wound. It will be difficult for you to see again, yes." Porlyusica commented looking at Erza's right eye.
"Now, now…" Makarov began. "I'm asking you nicely so no complaining. She's got such a pretty face, show some compassion would you?" Porlyusica gave a sigh
Ursa glared at Makarov. "Makarov… You're not thinking of laying her hands on her when she's older, are you?" she asked giving a slightly scaring the little old man.
"O-Of course not…" he replied while sweating profusely.
Erza turned away from all of them. "Where is she from?" Porlyusica asked. 
"I found her a few days ago." Ursa replied.
"Rob was helping her out." Makarov revealed.
"Rob?" The old pink haired woman gasped remembering him. "Where is he now?"
"It seems he's dead." 
Porlyusica was shocked and looked at Erza who now had a frustrated expression on her face.
…
Inside Porlyusica's home, she was tending to Erza's wound while Ursa was waiting by sitting on the other side of the tree. "It is finished." She said. Erza lifted the mirror to her face and saw that her right eye looked completely normal.
"It's healed!" she said, surprised.
"Can you see?" 
"Yes." Erza said.
Porlyusica walked over to another part of her home. "Then get out, immediately." She harshly said. "I hate humans, get it!"
A smile formed and Erza began crying from her left eye. "It's healed."
Ursa walked and looked at her face. "You look beautiful, Erza." She complimented.
Porlyusica quickly noticed something odd. "Wait… y-you're… You're only crying out of one eye." Erza looked at her reflection again to confirm what Porlyusica said.
"Is something wrong?" Ursa asked.
"That shouldn't be. I didn't make an error while mixing the medicine, and yet."
"It's okay!" she heard. "I've already cried out half my tears you see." Erza said while giving a smile.
…
Erza and Ursa were just outside Magnolia and Ursa was about to leave for her house. "You're leaving?" Erza asked with a slight shock.
Ursa nodded. "My husband and I want to travel this world; there is something that we are looking for."
"Why must you leave so soon?" Erza asked sounding slightly sad.
"There is something I have to do, I have to find a way to save my children."
"Zuko and Azula you mean?" 
Ursa nodded put her hands to Erza's shoulders. "Listen Erza, I know you will grow up to be a strong, confident person. Never forget that." They both hugged each other before Ursa walked away from Magnolia.
(Flashback End)
----Erza's eyes shot open as she was still inside the Lacrima. She was now in a white dress. It looked like she was falling underwater. "Where am I?" Erza asked herself as she continued to fall underwater and looked at a huge light above her. "Also, why did I just see all of that?" she wondered thinking back to the flashback she had just had.
"Erza…" When Erza heard her name being called out the voice sounded very familiar in her head but she wasn't able to place the source, she saw an apparition of Ursa looking down at her with a smile. "It is you, isn't it Erza?"
"Ursa…? How is this possible?" Erza asked.
The vision of Ursa got closer to her and she outstretched her hand and caressed her right cheek. "You have grown into a beautiful young woman." She complimented. "It is very admirable to do all in your power to save those that you deeply care about." Ursa's smile turned to a frown. "However, it shouldn't cost your own life to achieve this. What you are doing is causing even more pain to your loved ones." Ursa explained.
"Ursa…" The vision of Ursa hugged Erza.
"Friends and family are the are the best things you can ask for. Erza…" She ended the hug and looked at Erza. "...Go back to your family, don't abandon them, don't make the same mistake I did. And if I can ask you a huge favor, please take care of my son ...and daughter when the time comes."
Erza soon nodded. The vision of Ursa disappeared. "Ursa!" Erza yelled out but got no response. Soon after she sees two hands reaching to grab her. She outstretched her arms to reach them and she was now dragged out of the vision.
----Erza slowly wakes up and finds that she is on the shore but even more surprising was the fact that supporting her was Natsu and Aang on their shoulders, she could hear the both of them panting. "Natsu… Aang?" they both looked at her and smiled even though they were completely drained. Erza saw Appa with everyone on him waving to them. Appa was speeding to meet them on the ground. "So, this is the family. I was about to leave? Thank you, Ursa." She thought as she was reunited with her friends.
