Heavenly Deku

Going Berserk

Izuku after defeating the nomu powers down a bit and floats back down to the ground, with the threat defeated he can finally rest and not put that much stress on his body using his quirks, after floating down a fair distance he hears the voice of an adult male above him say

???: Kaijinryu!

Izuku barely reacts in time to put up an Ark barrier in front of the attack, but the force of the attack still throws him to the ground causing another dust cloud, students look at the dust cloud wondering if it's another villain, with the dust cloud fanning out the students see Izuku laying on the floor trying to get up until a young woman with long orange blond and purplish-black goop or liquid covering her private parts, her left leg, and right arm smashing down with a big claw made out of the same purplish-black liquid right into the stomach of Izuku, her using the same arm to punch him up into the air and hitting him over and over again, punching holes into Izuku's body, leaving him a bloody mess, While Izuku was being beaten over and over again, Aizawa and Vlad weren't able to do anything, to them the battle was a blur, they couldn't see what was happening so they just decide to wait it out. Finally, the woman hits him up into the air flying towards a flaming phoenix shot out by a man wearing a cloak, with purplish-black tendrils wrapped around his torso, and arms  with black pants and golden armored boots

The flaming phoenix causes a large explosion in the sky, Izuku then shoots down to the ground with a massive crater that shook the entirety of the USJ. Izuku stands up with holes throughout his torso, a beam of light shot into the air from the crater and after a minute, Izuku emerges out with darkness covering his body like what happened in the battle trials

Izuku with his transformation complete shoots towards the woman with the orange blond hair at lightning speeds landing a massive blow to the left side of the woman's face causing her to get blown away in a spiral motion, Izuku following that attack with more devastating blows leaving her to cough out blood, the woman was able to escape the onslaught by creating wings out of darkness and flying to where the man in the cloak was. Izuku following her up to where the pair was, Izuku decided to ask who they are.

Izuku: Who the hell are you and why are you here?

???: I'm Derieri and this is Monspeet. We're from The Ten Commandments, you have taken something from us, and we were sent to retrieve it. Now give us back the Commandment of Truth

Izuku: I'll give it to you when you pry it from my cold dead hands.

Derieri: Fine, we'll do just that.

And so the battle raged on, blow after blow, both sides of the conflict refused to give up, as Iida finally made it back to the USJ with the heroes, they see that the USJ is a blood bath, villains on the floor dead or unconscious and large holes in the ceiling. The heroes look up to see 3 people fighting, no one could reach them, All Might may be able to jump that high, but no one could stay in the sky for a long period of time, so they decided to have Present Mic to communicate with them or at least try to. The heroes wanted to clear out the bodies of the villains on the floor, so they had the students help them. The battle in the sky ensued while the heroes clean up the bodies, we can see that the pair was gravely injured, Izuku was injured as well, but not as much as the pair. Both sides backed up to regain some stamina, the pair then whispered something to each other and said.

Derieri: It seems like you're tougher than we imagined, we'll be coming back a later date with the others of The Ten Commandments, and we'll get that commandment from you, mark my words. 

And so Derieri and Monspeet flew off, leaving Izuku there floating alone tired from how much he had to use his quirks. Izuku then flew down with extreme amounts of caution because he's worried that another random attack will be fired upon him, but as if he was suddenly paralyzed, Izuku plummeted to the ground unable to move a muscle, he laid there not moving an inch on the crack floor he fell upon. The limits of Izuku's quirk breaks because of overuse, the darkness from his body all go into his arms creating claws the size of his body, markings of darkness appear on his forehead and all over his body, with his limits being broken, he enters into a wrath state destroying everything around him.

The heroes and the students see Izuku convulsing and destroying everything around him, they have no idea what's happening to him, all they see is the darkness on his body is moving and it seems to be causing a lot of pain to Izuku, some of the students want to get a closer look but Aizawa states that it could be dangerous if one of them gets hit. The students and the heroes see that Izuku is standing up, but upon closer look, it seemed wrong, Izuku's legs weren't moving, black tendrils coming out from his back are pushing him up, as Izuku stands up completely an animalistic roar is heard from him causing a large shockwave causing some to lose their balance, Bakugou decides to run in like a fucking idiot trying to stop Izuku but then gets slapped away like a fly, Izuku seeing Bakugou getting slapped away keeps his emotionless face, with eyes that could see into one's soul. Seeing his successor get thrown away like a doll from a kid having a temper tantrum he catches Bakugou and tries to stop him, Izuku seeing this also flies towards All Might. The battle of titans begins...
