Behold True Power!

Hello everyone, sorry if this is a little late but between the last chapter of my other story, traveling and some slight computer issues there wasn't much that could be done. But with no guest reviews this week the only other thing I have to say is here it is now, the finale of the Shie Hassaikai Arc!

Hassaikai Underground Lair

It all happened in an instant. One moment Clay was tormenting Chisaki with clouds he'd snuck into his constantly rebuilding body and the next, the ceiling burst open above them. The cloud user had stiffened at first upon seeing the body of Rikiya Katsukame until he realized who had slammed him through the ground in the first place. "It's Ryukyu, Tsuyu and Uraraka!" Said a surprised Midoriya.

"Hey it's Deku, wait," said Uraraka as she used her quirk to keep Rikiya floating, "how can you be here? You were just up there a second ago."

"There can't be two Midoriya's, so who's the other one?" Questioned Tsuyu, who currently had her tongue wrapped around Rikiya's body.

"It must be the League of Villains," said Ryukyu in her dragon form as she held down the Yakuza member, "We need too-Oh no."

"NIGHTEYE, TOGATA!" Exclaimed Uraraka as her gaze also fell on the two injured heroes near the entrance hole.

"Get them to an ambulance, quick!" exclaimed Midoriya as he rushed towards Eri, "We need too-." He was interrupted by the ground suddenly shifting and changing as a pillar shot the little horned girl into the air while a pair of branching spikes all shot out of the ground towards the heroes.

"Shit!" Exclaimed Clay as he attempted to use his quirk to stop Chisaki. But it failed as he realized the villain had used the moment of distraction caused by Rikiya crashing through the roof to heal his arms while also expelling the clouds within them.

"You disgusting heroes have screwed up all of my plans!" exclaimed Chisaki as he created a pillar beneath himself that rose into the air, catching Eri in the process.

"You're not going anywhere!" Exclaimed Clay as he rocketed up towards the rising pillar on his clouds. Midoriya came up the other side using full cowl to leap off of the debris that had begun falling from the ceiling due to the shifting of the room. The Yakuza leader turned to face them, but as he was about to use his quirk, Eri reached out and grabbed ahold of Mirio's cape which had been sent airborne by the battle. As she did so, her body let out a burst of yellow energy from her horn which caused Chisaki to actually split from his henchman as they both reverted back to their original human forms, disorienting them both for the moment.

"We won't let him have you!" Declared Clay as he created a cloud platform for Midoriya to jump off of while also sending a couple of smaller ones up to fend off the rubble between them.

"ERI!" Called the One for All holder as he stretched his hand out in midair. Amazingly, the timid girl who seemed to have no hope only moments ago, took a leap of faith off of the pillar and landed in Midoriya's arms.

"GIVE HER BACK NOW!" Raged a recovered Chisaki as he used his quirk to tear apart portions of the pillar and reshape them into giant tendrils racing towards the three of them.

"The heck you will," said Clay as he created a cloud cushion around his friend and Eri as to help him dodge around the pillars. "Midoriya, look for an opportunity to jump out of here and leave this bastard to me."

"But I can't just leave-," Izuku started to argue before another wave of pillars started coming their way.

"Our priority is to save that little girl's life," Clay called back, "you promised you wouldn't let her go this time right?" Deku's eyes widened as he remembered his promise before narrowing in determination.

"Just give me an opening," said the green-haired boy as Clay maneuvered them around even more tendrils and up towards the surface. Chisaki's desperation was clear now as he actually leapt off the pillar after them, his outstretched hand reaching towards Midoriya as Clay narrowly guided them through the twisting and quickly forming tendrils. But some of the tendrils had bent back towards them, attempting to trap the two of them there. None of them, however, were quite fast enough for what happened next.

"We will save you!" declared Midoriya as the energy of One for All flared to even more incredible heights as he pushed off of Clay's cloud with all of his might. It was far stronger than any jump he'd ever done as the air pressure wave actually demolished the stone tendrils around them and sent both Clay and the Yakuza leader flying away from the impact point. The U.A. student managed to form a tough but flexible cushion to minimize the damage from his fall before rolling off of it into a half-kneeling position. 'Now that was a jump,' he thought as he smiled, noticing that his mask and goggles had also been torn off from the air pressure wave.

"What in the world just happened," said Ryukyu as her dragon head looked around the scene and found no sign of Deku.

"That was probably a jump with his quirk at a hundred percent power," surmised Clay as he hovered next to the dragon hero, "That's the only time I've seen shockwaves that size from him."

"So where is-oh no, Chisaki," said Uraraka as everyone followed her gaze to see the villain a fair distance away staggering to his feet before using his quirk to fix his broken arm.

"Naughty girl Eri," said the Hassaikai head as he walked unsteadily through the rubble, "using your power on me of all people." He proceeded to reach down for something in the rubble.

"Not good," said Clay as he sped over towards their enemy just as he touched the body of Rikiya Katsukame.

"I need your power to realize the old man's dream!" Exclaimed the increasingly insane sounding villain as his and Rikiya's body was torn apart and reshaped once again in to that of an even larger, more grotesque creature with six red arms that stood ten feet tall if not more on two massive legs. A slightly inhuman growl sounded from the head of the monster, which had been shaped into a large version of Katsukame's mask as it revealed the upper body of the Yakuza leader in its mouth. As it spread its arms out and reached for the wall, a cloud nail jammed into the hand and knocked it away.

"I told him to leave you to me," said Clay as he released a large number of clouds from his body, throwing his usual caution with his quirk to the wind, "And I don't intend on ever letting you near that girl again."

"Meddlesome pest," growled the Chisaki hybrid as it glanced back at him before slamming one of its other hands on the ground. "BE GONE ALREADY!" Clay dodged out of the way as several stone tendrils erupted from the ground and swatted at him before countering with a half dozen large cloud nails, sticking them all where the arms began on the malformed body. But he didn't feel the skin give as Chisaki whirled around and swung at him with his elongated arms, forcing Clay to raise, lower and even jump off one of the arms before reshaping his clouds into the thickest buzz saw he could make and slamming it one of the arms.

He spun it as fast as it would go, creating sparks before finally drawing a bit of blood. "Pathetic," growled the hybrid man as he swatted the construct aside with another one of his massive hands, "this is real power!" He touched the ground again, causing more spiraling tendrils to come his way which forced the cloud wielder to increase his height in the room before reforming his clouds into drills. 'The skin's too thick for me to cut quickly, so I'll go for the actual body!' thought Clay as he sent the drills rocketing towards the body's 'head'.

The massive hands were too slow to stop the drills but the mouth was just fast enough to close as the projectiles impacted against it and began rotating at high speed. Once again, unfortunately, they weren't strong enough as Chisaki reached up with two of his new giant hands and used his quirk to disperse the clouds. "My skin is much thicker now that I've bonded with Rikiya. You pulled a nice trick earlier but now that it's rendered useless you're little more than a nuisance to me."

"You make it sound like this nuisance only has one worthwhile trick," Clay shot back as he reformed his clouds into a collar with spikes that jammed into the 'neck' of the monster that was Chisaki. "But what do you think of this: Grasping Thunder!" Bolts of electricity shot out of the clouds and into the body of the villain, producing a roar of more rage than pain as he dissolved the collar with his quirk to stop the attack. The cloud wielder used that opening to reshape his clouds into several hand-cuff like bindings that wrapped around and pulled Chisaki's six giant hands together.

The beast struggled to reach the bonds but couldn't as they were all located behind its wrists, preventing the Yakuza leader from using his quirk. "Now try a second shock!" Exclaimed Clay as he used his lightning attack yet again. While this was going on, Uraraka, Tsuyu and the others were looking on in a mixture of admiration and worry.

"He's winning," Uraraka thought aloud as she tried to struggle to her feet before collapsing back to her knees, "please tell me he's winning."

"He's surviving at the moment," replied Tsuyu, "but I don't know how much longer that'll last."

"Clay will survive if he doesn't pursue Chisaki," said the wounded Nighteye suddenly, "but he won't be able to defeat him."

"Then we need to get over there and help-guh," Ryukyu stumbled back to the ground, her own strength still drained thanks to Rikiya's quirk from earlier.

"I'm afraid none of you are in any condition to go after them," coughed Nighteye as Tsuyu continued to put pressure on the wound in his side, "once Chisaki escapes those bonds, he'll go after Eri and kill Midoriya to get to her."

"What, but that can't be-," Uraraka started to say before a massive roar filled the destroyed room.

"I've had enough of your interference you damn filthy hero!" Roared Chisaki as his arms managed to tear out of the cloud bonds that had been electrocuting him before slamming on the ground. His quirk activated then as the entire section of floor he was standing on and around him shifted and warped. The monster of a villain was lifted upwards by a large rising pillar while a mass of spikes shot out in all directions, growing even more spikes along the way. Clay was forced backwards as he narrowly avoided being impaled before getting trapped between a number of other spikes.

'Not good,' thought Clay as the spikes began to close in on him, threatening to crush him, 'I got one chance at this so here's hoping physics works the way Slade says it does.' The U.A. student wrapped his clouds around his body, directing himself towards the large hole in the ceiling as he felt the space around him shrinking little by little every second. He adjusted the density and pliability as quickly as he could and then, the hardest part, he waited. The pressure continued to build as his clouds were squeezed like a stress ball until finally the reaction he'd been waiting for occurred.

The current elastic nature of his clouds propelled him upwards as the stone pillars filled the space where he'd just been. Clay flew upwards several feet before using his quirk to call his clouds back into their signature cloud armor set as he exited to the surface to find Chisaki confronting Midoriya. The hero-in-training was understandably surprised to see his friend still standing given that he should've had a broken leg, but it did give him an opportunity. It also helped that the Hassaikai leader was currently monologuing about Eri's quirk.

"Her quirk isn't simple cancellation," said Chisaki as he stared down at Midoriya and Eri while Clay maneuvered around behind him, "she can actually rewind someone's evolution back to a time before there were quirks. What Eri truly represents, what she truly is, is CHANGE!" His massive reconfigured body began to lumber forward as Clay gathered his clouds and began building up as much electricity in them as he could. 'I still haven't gotten this move one hundred percent complete,' thought Clay as he produced even more clouds to join with the current mass in the air, 'but it's the only shot I've got right now for taking out an opponent like this in a single blow.'

"I'm the only one who knows how to use an asset like Eri!" continued Chisaki, "And with her quirk I will CURE THIS WORLD!" He hit the ground then, sending out his signature stone tendrils towards Midoriya and Eri. 'Shit it's not ready,' thought Clay as he spun the clouds at high speed, 'but it's gonna have to-huh?' He'd blinked right before sending out his attack, and in that time Midoriya had seemingly disappeared then reappeared right beneath Chisaki before kicking him with a massive amount of force.

It was so powerful, in fact, that his entire massive body was sent rocketing into the air high above the neighborhood. 'Wait a minute,' thought the U.A. student as he watched the battle in the air, 'Eri rewinds people, does that include injuries?' Apparently it did as Chisaki attempted to reform new arms and legs, only to get them blown off again by the One for All user. 'If that's true, then Midoriya can operate on one hundred percent power for as long as he needs!'

And he was using it as he smashed the villain's reformed limbs over and over in midair until he found an opening and slammed his fist into the Yakuza leader's face, knocking off his mask and sending him back to earth. Unfortunately, it was also right towards the same area he'd been launched from. "Ah nuts," Clay blurted out as he just managed to fly up and clear the area before the massive body impacted, blowing up a cloud of dust. "Now that was a show, I wonder what Midoriya thinks about-oh right he's still up there."

The U.A. student looked up just in time to see his friend falling back towards earth before forming a cushion with his clouds to catch both him and Eri. "Clay, is he?" Questioned Midoriya as One for All's energy still swirled around him.

"I think so," replied Clay as he glanced at the Hassaikai leader's unmoving form, noting the vacant expression on his face, "Kai Chisaki is beaten at last. I think you may have just won."

Wow, this chapter turned out shorter than expected but hopefully it was intense enough to be entertaining for everyone. Now a serious question for everyone: should I go ahead and kill off Nighteye, or leave him in an injured state that will prevent him from doing anymore hero work? I honestly have no idea how everyone else felt about his death in the show. Just let me know the usual way with comments and reviews. Also, let me know what you liked/disliked or if you've got any neat ideas for future chapters. Be sure to stop in next time as our heroes deal with the aftermath of the battle. 'Til then.
