With his heart pounding in his ears DynaMight blasted himself into the air, taking a distance from that savage red gaze. Chucking a flash grenade to cover his tracks he was pleased to hear Red Riot's shout of surprise.

DynaMight bit his lip, wracking his brains for a winning strategy. If his explosions weren't enough to graze Red Riot and the fucker wasn't going to run out of stamina-which it didn't fucking look like-the only thing DynaMight could rely on was his speed and agility. If Red Riot couldn't hit him, he couldn't bring him down.

Of course, DynaMight couldn't bring the bastard down either.

DynaMight weaved his way around the boulders, entering a more 'mountainous' part of the training ground-UA really took 'natural terrain training' seriously. Like this, with a solid vantage point he should be able to keep Red Riot at range. The idiot might have been able to tank one Ultra AP shot but DynaMight was betting a couple of dozen would break the fucker.

Instinct was all that saved him. The split-second sensation of the hairs on the back of his neck rising. The faintest whistle from air splitting had his palms exploding on reflex, sending him careening sideways. DynaMight only just managed to flip himself in time to avoid braining himself against the cliff face. As it was the impromptu landing left his ankles stinging and knees numb.

Dust scattered as a dark red pauldron smacked into the opposite cliff, digging in by several inches and cracking the rock. The cliff face crumbled with a echoing crack, creaking with weakness as the weapon was withdrawn with the use of a dark chain. DynaMight followed its path with wide eyes.

Red Riot grinned, swinging the pauldron above his head, the heavy gear nothing but a blur of red. Eyes following his preys every movement, he fired it once more.

DynaMight dodged with a curse, frantically changing direction in mid-air as further chains crowded around him. Snapping at his feet like feral dogs as Red Riot sought to pull him from the air.

"The hell!" Cursed DynaMight, when did Red Riot get so good at chain work? How the hell was he making them move like that? Chasing him into the air, changing direction to hunt him down. Even Aizawa's capture scarf didn't move like that. And Eraser Head had trained for decades to master his weapon. And just how heavy were those fucking gears!

Red Riot laughed, "Surprise! I solved my mid-range problem! Like it?"

DynaMight panted, wrenching himself to the side as another pauldron swung down from above, cutting off his aerial escape. He changed tactics, running along the cliff face instead, using his explosion to keep him in the air. Red Riot wasn't standing still, running parallel to him along the ground. Shattering boulders with his hardened shoulders as he went. Using the broken rocks as projectiles to further impede DynaMight's retreat.

Despite this DynaMight managed to take some distance, catching his breath and casting his eyes around, desperately looking for a way out.

"Trying to run?" Red Riot mocked.

DynaMight glared at him, blinking the sweat from his eyes. Red Riot stood calm, the last of his chains unwinding like snakes about his waist. The links clinked together, hovering menacingly in the air, arrow headed tips ready to pounce.

"I'm not going to let you run" Red Riot whispered, a hungry glint coming to his eye.

Red Riot changed.

Crouching, hands braced on the ground, the black wraps shredded as his legs hardened. Feet expanding and talons curving to dig into the ground. His back arched, each vertebra protruding like spines, a mountain range of serrated flesh. Each muscle of his chest shifted, hardening segmented like a carapace, allowing him to flex and breathed. His shoulders and arms grew heavy with hardened skin, cutting edges growing down his forearms. Those deadly pauldrons warped, moulding around his hands. Extending to jagged red claws several inches long and spiking his knuckles.

Finally, the hardening reached his face, whites of his eyes turning red from the crystallized blood. His jaw jutted forward with the expanding of his teeth. Sabered maw too much for his face guard, shattering it instantly. That mane of red hair stood spiked and deadly. Rippling down Red Riots back, clacking and screeching, sparks igniting, as the strands rubbed against each other. Finally, the chains became jagged, thorned.

The beast pressed one hand to the floor, claws lazily digging furrows into the concrete as he heaved in a rumbling breath, hungry.

DynaMight felt fear slip cold down his spine. His knees trembled, his breath caught. Red Riot, hardened tongue birthing sparks as it swiped over those monstrous teeth, growled.

"Red Riot: Predator."

Crack! Boom!

DynaMight felt those deadly claws shave away the flesh on his shoulder as he reacted a fraction too late. Red Riot having closed the distance in an instant, hugely hardened feet leaving behind craters. Frantically DynaMight guarded his throat. Red Riot's teeth closed around his gauntlet instead, shattering it and spraying the stored sweat into the air.

DynaMight released the switch, sacrificing it to that steel maw and launching himself backwards, weaving around the hungry chains. His breath came fast with fear, mind blank with shock.

He fired at AP shot as he retreated, hitting his destroyed gauntlet head on. The resulting explosion of litres of nitro sweat ignited a supernova around Red Riot's head, flinging him back. DynaMight didn't kid himself into thinking it would keep him down long.

He ran.

Red Riot hunted.

Teeth clacked as Red Riot worked the rest of the destroyed gauntlet from his gums, smoke rising around his steel like tongue. His red eyes were wild, crazed, out for blood.

Every time DynaMight fired an explosion to change direction a chain would be waiting, bladed edge swinging. Retreating from it would have his back pierced by diamond like claws. Trying to fly would be met with a loud crack, followed by an earth shattering kick from above. Explosion after explosion left him, fired blind in a hope to confuse his pursuer. Another flash grenade was battered aside by a chain before he had a chance to ignite it.

All the while wide hungry teeth drew nearer and the net drew tighter.

A rock flew at him from ahead, a chain having reached past his shoulder to pierce it. DynaMight bent backwards automatically as it whistled by him. Only then realizing his mistake as a granite like hand closed around his ankle, dragging him down. DynaMight fired shot after shot at the wrist holding him, releasing the full might of the stored nitro left in his last gauntlet. Burning his own leg in the process. Pain muted and hidden under primal terror.

The hold didn't lessen even a millimetre. Red Riot looms out of the smoke, mouth wide. DynaMight's back hit the ground with spine numbing force. The predator closed in. The prey fell still.

Teeth press against his throat and around a god chunk of his shoulder while DynaMight lays paralyzed. Death kissing against his pulse. Slowly, with great heaving waves of change, Red Riot releases his hardening. The chains fall lip at DynaMight's side, the claws crushing his stomach recede, the knee cutting off the circulation in his thigh releases its hold. Red Riot's teeth return to their normal state. Still sharp, still threatening.

A rumble vibrates through the redhead's chest, into Katsuki's own, tripping over his pounding heart. Release, adrenaline and sheer want surge through him, turning his spine to jelly and igniting his blood. Heat pools low in his stomach and Katsuki takes in huge heaving gasps, suddenly salivating.

"I win" grows Red Riot, lips brushing against Katsuki's neck as he pulls his head back a scant few centimetres. Red eyes meet red as he licks the salt of Katsuki's sweat from his lips, tongue flashing sensuously over pointy, dangerous teeth. Teeth that were just at Katsuki's throat. Teeth that he would very much like in other places.

Kirishima heaves in a breath, so close that the action has his chest brushing against Katsuki. Suddenly he stills, pupils widening, until only a thin ring of red remains. He takes another breath, mouth parted in silent question. A surprised, hopeful, wondrous look coming over him.

Kirishima meets Katsuki's flaming eyes and Katsuki holds his breath. Praying that he won't notice.

Kirishima flicks his eyes downward to the very obvious bulge in Katsuki's sweat drenched pants.

Embarrassment floods through him like a tide and he tries to close his legs on reflex, but Kirishima still has his thigh pinned so he can do nothing but twitch. Drawing even more attention to his 'little' problem. Red burns his face and Katsuki can do nothing but stare wide eyed into surprised crimson eyes, not even capable of looking away, and prey that Kirishima won't say anything.

So of course, he does, "Bakugou, what - what? You…You're-"

Fuck! Fuck! Fuck!

He knows! He knows! He can't-he doesn't! Katsuki needs to get out of there. He needs to leave now. Preserve what little is left of his dignity and lick his wounds. Lock himself up in his room and possibly never see the redhead again. Kirishima can't know, he was never meant to know. What…what is he going to do now?

A new light comes to Kirishima's eyes, determined, resolute. Katsuki's breath hitches further, weak knees trembling as the redhead dips one careful inch closer.

"Kiri! Oh my god, that was epic!" Kaminari smacks into Kirishima's back. Taking the both of them by surprise and toppling the giant from his perch hovering over Katsuki. The explosive boy grabs his chance, trance broken, and scrambles to his feet. The other extras are running over, all eager to pile on Kirishima, congratulating him on his win and asking about his moves.

Heart pounding wildly, skin shivering with desire and spine weak with shock, Katsuki does something he swore he would never do.

He flees.
