Jotaro
Jotaro is walking towards a door that has a forces retired hero because her quirk was stolen by AFO, Jotaro knocked on the door. Ragdoll thought that the heroes came to the hospital early to talk about the plan, but she get surprised that it was unknown man that was usually buff.
Jotaro quickly touched Ragdoll to use his time powers to rewind her time to the time she still had her quirk, this causes the same quirk for different time to be in the same time, and is causes one of the quirks to merge with the other quirk. Ragdoll wins because this was originally her quirk and Jotaro is controlling the time on her favor, the merge causes Ragdoll's quirk to evolve and become stronger.
Ragdoll is shocked at this action, but Jotaro used his time powers to stop time and leave the hospital before the heroes come in. AFO feels that Ragdoll's quirk was taken, this causes AFO to panic a bit because he didn't know what happened and he couldn't control this, he don't know who take the quirk he take.
The heroes came to the hospital to discuss the plan, the heroes decided about separate every villain for their chances to win, Ragdoll told the other heroes that Jotaro gave her quirk back and it's more powerful than before, Ragdoll tell Jotaro he message after he left. " We are going to help out in this war." Heroes were silent because of this unknown man, but Deku knew that man was a part of Ken's group and he tell everyone that they have an ally.
Deku tell them that Ken was the one that fixed the destroyed city, he is a leader of powerful group that were defeating dangerous villains and want to end AFO and Shigaraki chaos. The heroes were suspicious about this group, but They needed the help so they didn't really have a choice on this.
Two Days Later
Ken is waiting for Deku's signal when they can come in because Ken, his clones, and Star & Stripe were waiting in a building that was a few streets down from the current location of Deku and Yuga Aoyama were the battlefield would be at. Ken finally got the text of NOW, that was their sign to go, Ken created another clone, but this time a large dog named Bond.
Bond is a large dog of an indeterminate breed with fluffy white fur and black paws, noted by Anya to resemble the gloves and shoes of Bondman. His large stature, long coat, color, and the shape of his snout suggest he is mostly Great Pyrenees, and he is large enough for Anya Forger to comfortably ride on. Bond's eyes are small and dark, and he has small ears that usually droop down. Ken bought a teleporting power from his system to give to the dog, the teleportation is an instant and untraceable.
Bond teleported them to the battlefield and they see AFO, Shigaraki, nomus, David, and Toga were ready to fight and kill.Dabi was the first on to attack, he is targeting Endeavor for personal reasons. All Might uses a device to control the ground to imprison the villains, but this was only to restrict their movements.
The separation was successful with Monoma quirk, but Deku was grabbed by Toga with one of her tunes to suck blood out. Grimmjow jump in to follow Deku because he is the one that Ken ordered to protect him. Jotaro went with Endeavor and Shoto to defeat Dabi. Jotaro isn't having an epic fight and just hold back, Jotaro is used his time stop for 2 seconds to instantly be behind him and touch his shoulder.
The time stop ended, Dabi suddenly feel the hand and instantly attacks Jotaro, but Jotaro used his time powers to sent his age to 13 because that's the age he went missing and when it started his villain arc. " WHAT DO YOU DO TO ME, YOU BASARD." Dabi or Toya yelled at Jotaro who had a genuine pissed face toward Toya.
Jotaro created an attack that will make Toya experience the possible future of Jotaro hurting or even killing him, Jotaro is giving him all the pain he caused with the innocent that had nothing to do with his pain and Jotaro is pissed at his actions because getting revenge on the person that hurt you is one thing, but killing others because of this reason is crossing the line.
" I am giving you the pain that you caused with your obsession with revenge, Endeavor can't be excused with his past action, but he decided to improve himself as a person and hero, even if it's a bit late. Toya is barely conscious because he experienced possibly thousands ways that Jotaro can hurt or kill him. " I dealt with your villain problem now, now you have to fix your family problems now." Jotaro throws Toya to Endeavor and kill the nomus and villains that are surrounding them.
Wildvine
Wildvine is controlling the plants around the area to prevent Shigaraki from touching the ground to use his quirk, however, Shigaraki is touching his plants so they are instantly decaying one by one. Wildvine control another plants to grab Shigaraki an d stay there for a few seconds, Wildvine will grab the seeds on his back while Bakugo is launching a bunch of AP shots to the face.
Wildvine immediately throws his Explosive seeds onto Shigaraki and this causes Shigaraki to stay in the sky, Shigaraki planned to use Impact Blast to destroy the area and Wildvine because he is a throne on Shigaraki 's side, Wildvine is stopping him from touching the ground. However, that doesn't work because Monoma copied Aizawa's eraser quirk from using Impact Blast.
Shigaraki uses another quirk to make a wave of hands toward the ground and Wildvine, but Wildvine will throw his seeds on the ground to grow Venus flytrap that are the size of a bear and piercing the hands to suck out sustenance all of them and the arms started to decay. Shigaraki's wave of hands were suck out of life, decaying and the plants were going to his main arm, but Shigaraki cut off his arm to prevent the plants from basically killing him.
