All out, Dragon-Force Unions

"Sueong, you don't have to take him on by yourself." Natsu states, smiling, "Let us take it from here, you've done enough by coming up with strategies and wearing him down, a lot. Thanks."
"..." Sueong doesn't say anything and lets it be, glancing at Natsu, "This guy is too strong in the head, I'll give him that."
"You really think just because he landed a good number of strikes means that you can easily beat me? Ha HA." Acnologia is amused, "You mere dragons are out of options, that Ice dragon's last power-up was the only chance you all had against me... and looks what it did? He failed."
"Wrong, it means he weakened that diamond skin of yours to the point where our attacks will finally hurt you." Natsu rebukes.
"Try and enlighten me and give it all you've got!" The dragon kings ready.
"If you insist. Let's go!" Natsu charges.
"YEAH!" The rest follow and attack.
Wendy stays and puts her hands on Sueong's back, "I'll heal the injuries you received earlier." She uses her usual healing magic while he glances at the fight.
Meanwhile, Natsu goes for a straight-attack, which the dragon king blocks, "Didn't the Ice dragon warn you that reckless straightforward attacks won't work on me?" He taunts, "When are you going to learn? It's pathetic."
"And you're pretty slow. This isn't just a straightforward attack." Natsu rebukes before delivering multiple fire fists, but Acnologia dodges them back and forth with ease. Natsu then goes for an flame wave, which gets jumped out of. While in the air, "!" Acnologia notices Gajeel and Cobra about to attack.
"Iron Dragon Club!"
"Poison Dragon Sharp Horn!" 
They strike him from both sides, but the dragon king didn't felt that. "So that's what you were up to, but attacks of that level are nothing but weak and fail to even scratch me. None of you have the same power as that Ice dragon. Your chances of using basic tactics to take me on is useless." Acnologia comments.
"Basic tactics or not, we'll keep using them till they succeed." Natsu rebukes.
Suddenly, Rogues dives his head out of the shadow form the ground and grabs ahold of acnologia's legs.
"?" Acnologia is not alerted and looks down behind him at the shadow slayer.
"Caught you off guard there, didn't I? Arrogance will lead to your undoing." Rogue smirks, having used the chance to sneak through via shadows to get being him.
"Keep him just like that, Rogue!" Sting goes for a lighted fist, which Acnologia catches easily.
"Even if my legs are trapped, what are you gonna do about my arm?" He taunts.
"Already one-step ahead." Sting grins.
Laxus goes next, "Now you have nothing to defend yourself!" Laxus uses a lightning punch to aim for the back of his cape, which Rogue quickly takes cover and goes back under the shadows to allow Laxus to strike the dragon king, causing an explosion of lightning.
Out of the smoke, a magic repel surfaces and bounces sting and laxus out, "AGH!" They fly back.
Rogue comes out of the shadows and comments, "Tch, even that didn't work."
"We're not giving up yet. Sueong wore him down, and now it's the chance to damage him more. There's definitely a way." Natsu states.
"A way you say? Isn't the answer obvious? There's zero." Acnologia smirks, "The ice dragon behind you was the one planning your every move almost throughout this fight. On top of being the only one that was worthy of entertaining me. Without him, none of you can hope to ever beat me."
"You don't decide whether we have a chance or no chance. We decide that ourselves!" Natsu declares.
And as he was about to charge, a second wave of ice comes into play, making Acnologia jump.
By the time he's in the air, "Sky Dragon Roar!" Wendy attacks as well, hitting him in mid-air, but it's ineffective as the dragon king lands on the ground.
The other slayers see the two join back in.
"Sueong! Wendy!" Natsu exclaims, grinning.
"Until this guy is dealt with, I ain't never throwing in the towel. Even if I used the last of ichigoneal's ice." Sueong declares.
"Heh, you said it." Natsu agrees, "It's a surprise your joining again already."
"Don't worry about that. On the other hand, basic tactics will not work as I've already said before." Sueong states, "It's time to step things up a notch!"
"Such as... Dragon-force." Sting gets it.
"Count me in, it's now or never!" Wendy agrees and powers-up in dragon-force.
"Now we're talkin, time to go full throttle!" Gajeel gins and goes shadow dragon-mode.
"You bet!" Rogue goes dragon-force.
"This guy is in for a pounding!" Sting goes dragon-force.
"Sound good. This is to win and survive after all!" Laxus goes dragon-force.
"I can hear it..." Cobra take off his jacket and goes dragon-force too, "Everyone's fighting spirits!"
Natsu and sueong know they can't use theirs due to the previous battles(Zeref fight and Using full Ice dragon king mode)
"Anything goes will harm him this time!" Sueong decoares.
"Lets go!" Natsu exclaims and fires up.
"YEAH!" All 8 slayers charge at the dragon king with all their might. About to attack.
"Pathetic dragons. Your struggling is futile... I slay all dragons!" Acnologia declares and sets straight.
All dragon slayers attack him at the same time, which he counters in all sorts of ways:
Natsu goes for a fire fist, but gets kicked away, "GAH!"
Sueong attacks with his Ice-armed blade, but misses twice and gets punched back, "GHA!"
Gajeel goes for a iron sword attack, but misses and gets kicked back, "AGH!"
Wendy tries a sky wing attack, but misses and gets blasted back, "AH!"
Sting and Rogue lung at him to attack but get thrown to the ground, "UWAH!"
Erik(Cobra) jumps at him with a poison fist, but gets kicked to the ground too, "GAH!"
Acnologia grins at his onslaught and sees Laxus coming in last with a lightning fist, which he blocks and repels him back with a blast, sending him crashing to a crystal wall structure, "GAH!"
"Heheheh!" The dragon king grins and looks on to the next attack.
Natsu and Gajeel do a combination attack, "Fire Dragon..!" "Iron Dragon...!"
"ROOAARR!" A big hurricane form both.
Acnologia simply cuts the attack with a wave of his hand.
In the air, Sting attacks, "HOLY RAY!" He rains down a barrage of white lasers, which Acnologia jumps back and dodges them all.
While he's in mid-air, "Shadow Dragon SHADOW BREATH!" "Poison Dragon ROAR!" Rogue and Erik do a combined roar and strike Acnologia, who holds the roars back with his bare hands, but still gets crashed up in the crystal structure.
The dragon king gets out, but by the time he lands, he gets struck by the ice serpant dragon, "Ice Dragon King ICICLE BEAST!" The dragon serpent bites on the dragon king, who hold it's mouth back, but he gets rammed through many crystal structures across the rift. By the time Acnologia forces the serpent off him, it however, smacks him with it's tail, sending him upward into another crystal.
Wendy dashes next and attacks, "Sky Dragon GREAT WAVE WIND!" She catches Acnologia in a tornado and it sends him crashing through many crystal structures as well.
Laxus jumps in the air and forms lightning in his hands, "Lightning Dragon HEAVENWARD HALBERD!" He throws a lightning trident and strikes him to the ground.
Once the smoke clears, Acnologia's eyes are glowing red, with an excited grin look on his face, looking to have taken some damage, "You inferior dragons have done it now!" He opens his mouth and fires a humongous roar, sending multiple blasts all over the rift, causing a big explosion and destroying many crystal walls/structures.
As the smoke clears, it's reveal sueong's Ice wall protects them all, but shatters due to taking all the blasts.
"*pant*pant*" That took a lot out of sueong.
"Thanks for the shield." Rogue stands up.
"It seemed like our attacks did hurt him that time. Especially telling by what he said before firing that roar." Laxus notices.
"I was thinking that as well. Going dragon-force successfully amplified the attacks to hurt him." Sueong states, "All it takes is another big attack."
"So if we attack like that again..." Wendy figures.
"Then it'll be the last one that puts him out of commission." Gajeel grins.
"All right then, one more combo attack it is!" Natsu fires up.
"You really think you'll get another chance at using that combination? Think again. My power is above the whole world's paygrade. Unrivaled, unreachable, and unopposable. You feeble dragons will know your place." he then grins, before firing a beam, which they dodge and separate from the other.
Natsu, Gajeel, Laxus, and Erik on one side while Sueong, Rogue, Wendy, and Sting are on the other.
"I'll show every last one of you what power really means!" Acnologia begins his assault and appears in front of Laxus.
"!" The lightning slayer tries retaliating with a lightning Iron fist, but it gets blocked with bare hands and Acnologia slashes him across the shoulder, "GAHA!" Laxus boreds form that spot, but does give up, "HAAA!" Laxus goes for a lightning punch, but it gets brushed off and he gets kicked back into a crystal wall, out of dragon-force and now unconscious.
"Laxus!" Gajeel exclaims before trying to attack, but his Iron shadow sword gets caught and Acnologia slashes him with his hand across the chest as well, "GAH...!" He's then punched back to the ground. Out of dragon-force and unconscious.
"Gajeel!" Rogue exclaims.
"That's as far as you go!" Natsu lights up his fist and attacks, but Acnologia dodged before kicking him to the stomach, "GHA...!" He spits out blood and is send crashing through a couple crystal walls, smoke arising.
"Natsu!" Wendy exclaims.
"I've had it!" Erik goes for multiple poison slash attacks, but Acnologia dodges them all and gives him the same treatment as well, "GAH...!"
"If I recall, you tried reading my thoughts earlier in the battle. Digging into a king's thoughts isn't in your place." Acnologia smirks as Erik's blood splats.
"Now we're dropping like flies." Sueong scoffs.
"He took out Natsu and the others with one hit..." Sting trails, "He's trying to finish this fight now."
"With his bare hands, he could slash through us." Rogue adds.
"That's what we have to careful of. Surprised he didn't do it before." Wendy mutters.
"He was messing with us. but after inflicting him with Ice dragon king blows, and on top of you guys going dragon-force... he's not messing around anymore." Sueong states, "It's just the 4 of us now." He ices up, "One big attack is all we need, even if we decrease from 8 to 4."
"Better said than done." Rogue said.
"Another shot at this." Sting adds.
"Yeah, we won't give up." Wendy agrees.
Acnologia grins, "4 down, 4 to go. Will you feeble dragons entertain me longer? Or die quickly?"
"The latter would be you." Sueong rebukes before sending an Ice wave his way, which he jumps.
"Holy Ray!" Sting fires while he's in mid-air, which Acnologia magic repels.
"The same tricks won't work twice." He taunts.
Little did he know, the Holy rays then expand a bit with shining light, which blinds Acnologia, "Tch...!" His lower half and arm is then trapped by Sueong's Ice wave.
Using this chance, Wendy rushes in and attacks, "Sky Dragon's: Crushing Fang!" She uses her whirl-winded finger-tips to strike his chest.
Acnologia look to have felt that, but smirks and then breaks his arm free out of the Ice and grabs her arm.
"!" Wendy looks up at him, shocked.
"The Sky crushing fang, eh? Shrugging this attack was hardly worth hthe effort. These type of attacks will never put me down." Acnologia grins and was about to retaliate until...
"Shadow Dragon's: Waxwing Slash!" Rogue comes from behind and slashes him across the back, also tearing his clock, "!" This also allows Wendy to get distance as well.
"Thanks to that Holy Ray, you left a shadow on the Ice." Rogue reveals, coming out of it, "You let your guard down again and kept underestimating us."
Acnologia turns his head and frowns, "You'll regret that." He unleashes a magic burst, blowing rogue out of the shadow and them back. Also the Ice as well.
"There's more where that came from!" Sting jumps, so does wendy.
"White Dragon's: Holy Breath!" Sting fires.
"Sky Dragon's: Tornado!" Wendy adds.
Acnologia counters the combined attacks with a finger-beam, which also expands the white radius, "He's trying to blind me again..." He then looks behind him and sees his shadow up, "Pfft, the same and obvious trick won't work twice!" He waits for rogue to appear, but he doesn't, "Hmm?" He then notices the shadow right in front of him, "It was the other way around!"
Rogue comes out and brings Sueong out as well, with his ice blade ready, "It's over!" He then thrusts his ice dragon king blade through Acnologia's center chest.
"!" The dragon king felt that.
"Your finished Acnologia. Time for you to freeze!" The ice expands from the blade.
Rogue retreats him and himself through the shadows back to Sting and Wendy, getting their distance.
"That outta do it." Rogue figures.
"Not yet." Sueong forms a spear, "Another blow from this Ice dragon king spear will do him in."
"I'll enchant it." Wendy does so and powers-up the spear.
"Thanks." Sueong then throws it at Acnologia.
"!" He sees it and when it strikes him, an Ice explosion rises.
"Thinks will be turned around this time." Sueong is sure.
As the smoke clears, "*pant*" Acnologia is fine from the smoke, having magic repelled just in time.
"Grrr..." Sting and Rogue are stunned.
"That still didn't do it?!" Wendy is too.
"Would you just die already!" Sueong gets annoyed.
"That's the last strategy to ever cross your minds." Acnologia lets out his hand in a claw-like position, "I'm ending this now."
"Just try it then!" Sueong rushes in, followed by the rest of them.
"You feeble dragons are full of openings." Acnologia reads them and then hand-slashes them in many ways: Sueong across the shoulder, Wendy across the back, Sting on the side chest, and Rogue across the chest.
Blood splats out of each of them, "!" Which shocks them.
"Damn it...!" Sueong curses as they fall to the ground.
"Heh heh." Acnologia chuckles at his domination.
