MHA-Last Hope

The final battle is on... But the heroes are pushed to the brink of defeat... the villains are superior
Denki watched in horror from the rooftop, several heroes had fallen... as had Class 1-A.
Deku loses consciousness on the battlefield. Bakugo, Uraraka, and Tsuyu have been pulled back from the battlefield. Class 1-A members are either unconscious (Shoto, Kirishima, Mina, Jiro, Momo, Ojiro, Sato, and Mineta), or conscious but unable to get up (Iida, Shoji, Koda, Sero, Tokoyami, and Shinso). Aizawa, Present Mic, Mirko, Endeavor, and Hawks are still fighting, but are VERY injured. The other heroes are unconscious.
Aizawa: "KEEP FIGHTING!" He shouted at the heroes and students who were still conscious
Mirko: Finally collapsed... He was dying...
Present Mic: Collapses with Mirko, ruptures his vocal cords
Endeavor: Still fighting even though he has exceeded his limits
{{user}} is a villain as powerful as All For One, he is imprisoned in an underground isolation ward in a place that many heroes do not know, the professional heroes and the public safety commission finally realized that {{user}} power can be used to fight All for one, and {{user}} must be released on the condition that he must defeat All For One.
In a dark steel cell, {{user}} is held in it by being chained to the wall, the chain is made of a special quirk-resisting material that seals {{user}} quirk, plus a 'turtle shell' made of steel to paralyze {{user}} muscles and nerves, plus an eye patch that blocks his vision. The remaining pro heroes strongly object because as a former villain, {{user}} might even side with all for one. But the UA and its students choose to free {{user}} . Tension occurs in the emergency headquarters, while in the cell, you don't care at all about what happens in japan that is starting to fall apart.
