Trump Card

Time Rift: 
In the time rift, the fight between the Dragons Slayers and Acnologia rages on.
"Let's step this up a notch, shall we?" He grins menacingly as he walks forward.
"He's finally about to be on the offense." Rogue comments, "Be careful guys." They nod in response.
Acnologia suddenly vanishes.
"What?!" Natsu exclaims, shocked, as well as the others.
"The hell?!" Sueong thought.
The dragon king suddenly appears and Natsu tries to attack him, but he ends up getting punched hard to the ground.
"GAAH!" Natsu yells in pain.
"!" The other slayers quickly turn and are alerted.
"That speed!" Sueong thought, stunned.
"So fast!" Laxus thought
Acnologia teleports and suddenly punches Sting and kicks rogue, "GHA!" They both are sent flying. Next, he does the same to Sueong and Laxus as fast speed, making them spit out blood, "UWAH!"
Gajeel tries an Iron roar, but that has no effect on Acnologia and he rams his fist right into Gajeel's stomach next, "UWHA!" It makes his vomit and sends him crashing to the shard wall. Cobra goes for a Poison clawed right-hook, but it gets swatted aside and he ends up getting kneed in the chest, "GHA!"
Natsu and Sueong go for Fire/Ice fists, coming from both sides, but Acnologia grabs sueong's attack and slams him right into natsu, "GAH!" Making them crash to the ground. Wendy tries to attack with a wing attack, but it gets arm blocked and she gets kicked in the stomach as well, "UGH!" And sent crashing to the wall as well.
With all the dragon slayers down, Acnologia then fires a finger beam, "It's over." The impact cause an explosion in the time rift, "Haha... HAHAHAHA!"
Once the smoke clears, a huge ice wall just got shattered, revealing sueong put it up at the last second, "*Pant*Pant*"
"Still alive eh." Acnologia narrows a brow, not bothered and just smirks.
Some of the dragons slayers are down on the ground, with Natsu and Sueong on one knee.
Acnologia stands high and mighty, not having any injuries at all, "What's the matter? Is that all you weak inferior dragons have?"
"Grr..." Natsu struggles to stand.
"This guy is a total menace..." Gajeel pants, and the other dragon slayers are groaning as well.
"Didn't you say you had a 'Trump card'?". Acnologia directly asks Sueong, grinning in amusing, "I hope this isn't what you meant. That would be a really shame and pitiful sight-see."
"Heh." Sueong stands up, ignoring the injuries, "I don't need your arrogant taunting to tell me that." He then powers up, Ice aura flowing around him, "You think I would fight you again without being prepared? Fat chance!"
"This temperature..." Sting mutters.
"All of a sudden..." Rogue notices.
"It's getting cold in the air..." Wendy adds.
"What type of power is he planning to unleash?" Cobra wonders.
"Whoa..." Natsu's eyes widen.
"Hmm..." Acnologia only glares and waits for what he has up his sleeves.
Sueong, with a glaring face, un-bandages his left shoulder and below his guild tattoo, the hidden tattoo comes into view and is revealed to be a blue color dragon-looking shaped tattoo. Flowing with Ice on his arm.
"What's that tattoo on his arm?" Sting wonders.
"Is this the trump card Sueong was talking about?" Gajeel wonders.
"This is something different... I can tell." Wendy nods, surprised.
"What..." Natsu widens his eyes, stunned.
"This magic power..." Acnologia himself is a little taken back.
Sueong smirks as Ice sharps on his shoulder, "You asked for it, right Acnologia? So here it is at last." The crystal ground itself starts to turn into ice by his presence, a good radius of it spreading.
"Now the grounds start to freeze. Sueong's magic power is increasing dramatically." Rogue figures.
"So this is what was behind your bandaged sleeve all along." Cobra now figures.
"Incredible." Laxus comments, surprised.
Natsu gets a feeling from this level of temperature, "Hold on... this is just like..."
"That Ice reminds me of the Ice Dragon King." Acnologia recognizes.
"That's right. This is the remains of Icigoneal's power." Sueong reveals, "After rigorous training, This mode took me 9 months to control. There are a couple of flaws. The time limit and it can only be used once."
"9 months?!" Natsu is stunned, "That mode he's about to use took me 10 months to control with Igneel's flames."
Sueong tightens his ice covered fist, and powers up more, "Ice Dragon King Mode!" A spiral of Ice surfaces around him. Spreading and freezes the entire crystal platform they're on, instantly.
Acnologia widens his eyes, surprised.
"Woah...!" The other dragon slayers are too, but amazed as well.
"He has a Dragon king mode too." Natsu mutters, taken back and then grins in amazement, "That's so awesome!"
"Did he have to freeze the whole area? We're on Ice here." Cobra sighs, but grins anyway.
"Who knew you had a tremendous Ace up your sleeve. Surprised you didn't use this until now." Acnologia grins ready for it, "You're planning to take me on alone? I did say I would take you out first so go on and surprise me before I strike you down."
"I'll be doing the striking here, except it'll be way brutal." Sueong grins back and gets ready to attack, immediately forming his ice-armed blade, "It's show time... Here I come!"
With instant speed, He goes behind Acnologia and goes for a slash, which barely gets block, "Sudden speed." The dragon king expresses surprise before seeing the ice blade he's blocking is starting to freeze his arm, "!"
While in this inner lock, Sueong connects an Ice punch to Acnologia, sending him back.
"What power!" Sting comments.
"At this rate, we might finally get a hit in." Gajeel grins.
Acnologia is fine from it, having defended himself in time and breaks the escalated ice off arm as he's a few distances apart from Sueong.
"Now I see how much power that mode gives you." Acnologia smirks and understands, shaking off the ice, "Whether a being dodges or blocks, your strikes still freezes a part of their bodies that's aimed at due to the range and cold Iced atmosphere. Such escalation, but still nothing to me."
"Oh really? Guess I'll just make it cooler." Sueong continues his assault with polar fist, which Acnologia reacts and blocks with his one hand, but it still freezes. Sueong does stop and continues a multitude of Ice polar fist barrage. Only left with blocking everything via one arm, Acnologia smirks and lets out a magic burst, repealing sueong back a bit and also freeing own arm from the Ice. He then goes on the offense and fires a finger-beam.
Sueong doesn't move, only glares, and by the time he's almost hit, the beam itself freezes up and shatters.
"Hmm?" Acnologia's a little surprised.
"A flex of his magic and presence froze the beam?!" Rogue is stunned.
"Similar to how I burned Zeref's spell..." Natsu mutters, but amazed. So are the rest, "Too bad I can't go fire dragon king mode due to my last battle with zeref."
Sueong only frowns and proceeds with his Ice blade, "Now it's my turn." At fast speed, he slashes Acnologia across the shoulder, finally getting through his diamond-like skin and being the first out of the 8 to do it.
"!" It stuns the dragon king, but he doesn't bleed due to being in spirit human form.
The dragon slayers are surprised as well, but amazed.
"He did it!" Wendy beams.
"We finally got a hit in!" Sting said.
"Heh." Natsu grins, "We'll turn the tables now."
Acnologia gets back and sees the cut on him, which causes him to grin menacing, "Inferior dragon... how dare you cut me."
"It'll be more brutal than that." He replies and adds, "Since it's now an Ice battlefield, welcome to my world." Sueong blows ice fog out his mouth before swinging his hand forward, a large wave of Ice flash-freezes Acnologia, almost filling the whole time rift surroundings.
"That was an instant." Laxus said.
"Captain cold's really giving it to him." Gajeel smirks.
"Either way, that was a great shot." Natsu grins.
A sound is then heard in the ice, rumbling sounds.
"Hold on, what's that sound?" Cobra speaks out as they keep hearing it.
"It's coming from inside the Ice!" Wendy points.
The Ice cracks and then shatter explodes, revealing Acnologia, who steps out and shakes off some of the rust, "That impact was great one. Totally cooled me down." He grins, before saying this to Sueong, "I guess I'll commend you for landing a couple blows on me... but that's the last time you'll get that chance." He starts powering up, having purple-like sparks around, "Keep entertaining me. Let's have a splendid fight to the death!"
Sueong only frowns and attacks with several large ice pillars, which Acnologia hops back and dodges them. Sueong uses this chance to get behind him with fast speed, forming his Ice-arm blade, and proceeds to strike, but it gets blocked by the dragon king. By the time Acnologia sees his arm freezing, the purple electric around him counters it and keeps it from escalating further, "How many times must I tell you, magic doesn't work on me!"
"Heh, we'll see about that." Sueong isn't bothered and continues his assault. Now both of them are fighting in close combat, Ice sword clashing with one fist. Neither giving an inch.
"Sueong's completely going toe-to-toe with him!" Gon Gajeel exclaims, surprised.
"It's amazing." Wendy mutters, amazed.
"Is it safe to say we'd just be in the way?" Sting wonders.
"It seems like he has it under control." Rogue nods.
"No." Natsu speaks up, gathering their attention, "We'll use this chance to try and find an opening, that way we'll win this together!" He encourages, and receives nods as they get up.
Sueong and Acnologia keep clashing, even moving at fast speed all over the platform until the Ice slayer finds an opening and ice punches the dragon king in the stomach before jumping and delivers a couple kicks, which acnologia blocks with ease, but those were just distractions and sueong throws his Ice blade, aiming at acnologia's face and the latter barely dodges it, only landing a slight scratch on his tattooed cheek. Acnologia quickly recovers and by the time sueong lands, he punches him in the stomach.
"Gah!" Sueong flies back, but quickly regains footing. When he looks up, Acnologia comes down with a kick, and he quickly rolls out of the way, letting acnologia's feet crash into the ice ground. Out of the fog smoke, the dragon king continues with a dash punch, and sueong forms an Ice shield on his arm just in time to block it, but due to acnologia's strength, he's still sent back and the ice shield still cracks.
"Is that all?" Acnologia smirks.
Not saying a word, Sueong puts his left fist on his hand, creating a large Ice Eagle and Bull, much to the surprise/amazement of the other slayers. The two charge at Acnologia, who only grins and jumping on the incoming bird, shattering it with a punch before pointing a finger beam at the Bull, destroying it as well. Little did he know, those were just decoys and an Ice pillars strikes Acnologia from the ground and into the air, "Tch." He scoffs.
"And now." Sueong claps a hand to the ground, "Ice Dragon King's: Icicle beasts!" 2 serpent dragons form from the ice ground and make there way up to Acnologia, biting to devour him, ice fog in the process.
"Amazing...!" Natsu grins.
"A direct hit too." Sting adds.
"Not bad." Gajeel smirks and wendy nods.
"His ice magic really is off the charts." Laxus states, impressed.
As the serpent dragons continue devouring up, "Heh heh." Sueong smirks but then notices, "!"
A burst of magic destroys/shatters the ice twin dragons plus the pillar. Acnologia comes out, unharmed and flies down at sueong, "Whatever you do is futile!" Acnologia goes for a power amped punch. Sueong jumps out of the way, letting him crash into the ground.
Acnologia recovers and fires a large beam out the smoke. Sueong waves a hand and freezes it, shattering it like nothing.
"Kuh." Acnologia scoffs at that not working as he lands, not too pleased.
"It's the other way around. Your beams are useless." Sueong smirks and rebukes before going on to freeze Acnologia's feet, trapping them and escalating, "Now... Ice Dragon king's: Icicle Spear!" He creates and throws, which hits the dragon king head on, ice exploding in process.
"After all of that, this should get him." Laxus hopes.
"He can't be standing up from all of sueong's advanced ice attacks." Cobra agrees, "They were all direct hits."
Sueong pants and sees the bright blue dragon tattoo on his left shoulder starting to disintegrate, "Damn...The 10 minute time limit almost up for this mode... I know that roar didn't put him down. I'm finishing it with this next attack." He pants a little.
Out the ice smoke, Acnologia's still standing, but with Ice over his arm, which he shakes off, "I won't lie, that stung a bit. Very intriguing, but this is the end of the line. Adding to the fact that your trump card is almost used up."
"So what if it is. I still got enough of Icigoneal's power to kill you." Sueong responds before powering himself up even farther, cold temperature in the air as usual, forming a spiral icicle fist to finish it off.
Acnologia only grins as he witnesses sueong's final dragon king mode attack.
"This is it, Acnologia!" Sueong jump dashes forward, ready to strike.
The dragon king fires a black-like beam to try and stop him, but the cold radius of sueong's magic allows him to power through, Much to his surprise.
"HAAAAAAA!" Sueong shatters the beam and with fast speed, appears in front of Acnologia and lands his final blow at his chest.
"GAAAAAH!" Acnologia yells in pain before getting sent all the way back against the shard wall, crashing into it.
The other dragon slayers are stunned and eventually amazed at that last blow.
Now with that attack done, Sueong falls on his knees, exhausted from using the rest of Icigoneal's power, the dragon tattoo now erased off his left arm, "Phew... that was every last bit... of Icigoneal's power embedded in that strike..." He pants hard.
The dragon slayers are amazed.
"He actually defeated Acnologia... Man, I sure wanted to get a shot in on him." Natsu sighs, but grins anyway.
"Way to go, sueong." Wendy smiles.
"Not bad, Captain Cold." Gajeel grins too.
"That devastating blow definitely should have ended him." Sting nods.
"He was tough, but this time it's over." Sueong pants a bit, "That was the last time he'll be seen."
"That's great news then." Sting nods.
"Now we have to find a way to get out of this place." Laxus looks around, still the time rift.
"If all we had to do was defeat him, then in seconds, we should be teleported out of here, so what gives?" Rogue thinks.
"That's because... I'm stilling alive and kicking!" In a burst of Ice smog, Acnologia appears, having survived sueong's last attack.
The dragon slayers are shocked, especially sueong.
"What?!" Natsu exclaims.
"But how?!" Sting exclaims does too.
"No way!" Wendy too.
"What a monster!" Cobra scoffs.
"You've gotta be kidding me...!" Sueong widens eyes, shocked.
"I'll be honest with you, that did hurt quite a lot, you bastard." Acnologia grins at sueong and shakes the ice off, "But I, the king of dragons, have infinite power and will not falter over a mere attack like that!" He goes on to charge a finger-beam at him, "Now that you've ran out of time on that mode, this beam will penetrate right through you."
"Damn you...!" Sueong pants, "I used up the rest of Icigoneal's power, what now?" 
"You did well on providing me a fun battle, very worthy... but it's about time I kill you now." Acnologia fires his beam towards the Ice slayer, who was exhausted to dodged and defenseless.
As the beam was about to close in and strike sueong, Natsu jumps in and counters the beam with a Fire fist, saving him.
"You're getting way too ahead of yourself and forgetting that the rest of us are here." Natsu states at acnologia. The other dragon slayers come in as well, in front of sueong. He looks and sees their determination.
