Iron Might/All Might
Iron Might is in sync with each other because they can get work together without saying a world because of their being a hero. You need to work with people without saying a word to do some of their work and it's coming in useful.
" Toshinori Yagi, I grant you superhuman strength that you can handle." All Might's body is buffing a bit because of Star & Stripe's quirk, All Might is half his body mass now when he is in his buff form. His suit is stretching and bending a bit, but it's advanced technology is calibrating to this change.
Both now punching AFO's face and quickly deage him before he notice that he needs to retreat or something.
Star & Stripe quickly said All Might's name and do another advantage with her third rule. " We will swap places when I wink my eyes." Both heroes are opposite sides of AFO and are quickly swapping places as they are kicking his ass.
" Shit, I can't focus with them swapping places, that means I have to do a destructive quirk that may damage my body a bit." AFO's body is regenerating back to a healthier state, but he is being kicked around and he is using the quirk now.
The quirk was a wind-based quirk that is so powerful that it shreds through anything even the user, so all of them are going to take some damage. Star & Stripe block mos of the damage, but her has some major cuts on her body. Iron Might is blocking his head because of his exposed skin that can get damage, his armor got most of the damage as blood from his cheek drips to the floor. AFO was the worst as bone and skin were flying out towards the heroes, AFO stopped using the quirk as he got the two heroes away from him.
AFO is heard faded popping sound that get louder as Bakugo used AP shot on him, his body was getting younger and younger that he can notice it now.
Iron Might open his chest to reveal speaker, Star & Stripe got the hint as she change her first rule on her superhuman strength to powerful vocal. Both of them shouted to cause waves of sound caused AFO's ears and eyes to pop out with blood. Iron Might don't give mercy to AFO as AFO's version of Tsukuyomi's quirk combined with I cannot stop twinkling quirk piercing right through AFO body.
AFO is panicking a bit because his body is getting very young that his large amount of quirk are being limited and the drug doesn't allow him to steal quirk because of rewinding time back to a younger age that he don't have that quirk. AFO is now using all of his powerful quirk in all directions because of how desperate he is to kill them.
He suddenly paused as his body freeze for some reason and he can only use Bakugo charging a powerful attack with a mischievous smile. " ALL MIGHT, THIS IS YOUR CHANCE, KILL HIM FOR GOOD SO YOU CAN FINALLY KILL ME LATER." Stain was riding the metal version of dark shadow as he lick his finger that is covered in blood that he take from his bloody ride.
Bakugo pull the pin from his gauntlets as a large explosion covers AFO's body as his body had to regenerate his cells multiple times as he was getting closer to a baby's age as AFO's quirks weren't even in the double digits anymore because he couldn't steal as many quirks as he was in his younger years.
All Might uses Tailman's quirk to smash AFO's body to mush a couple of times as AFO was now a baby that couldn't speak anymore as his face showed every ounce of hatred that AFO had for All Might.
All Might was holding the baby from the head as he was planning to crush the head of the baby AFO to finish what he should have done years ago, but a hand touched baby AFO as he exploded to small pieces multiple times as Overhaul touch were he was reforming to end his life. Overhaul even douse the area where AFO with fuel and Jotaro throw his lighter in there to make sure that AFO won't suddenly regenerate and killed one of them when they were not looking.
" That was for your student taking away my arms to use me quirk, your shit pile of a demon lord." Overhaul spits towards the fuel as he chuckled a bit as a small taste of revenge was pretty tasty or bittersweet now because he don't kill Shigaraki, he can't because of Ken's orders.
" We should head to Deku and Shigaraki because the fight is it over. Are you join in this battle, if you aren't then stay out of our way because we have people to save." Bakugo fly off towards the floating island with Star & Stripe.
All Might looks at Ken with a smile as he expand an hand to shake Ken's hand. " I know that you help me in that battle, I may be out of my prime, bur my mind isn't gone yet. Thanks you for everything that you have done, you made this war possible and as a former number 1 hero, I am grateful that you had appeared here." Ken shake his hand with enough strength that All Might can feel that give the expression that Ken respected All Might.
" You're welcome, I was planning to do this war when the early stage of it were happening. I respect your work and other heroes work, you are risking your life to protect against a man child. We will catch up, but will still have thinks to do." Iron Might floats away with Stain on his metal dark shadow as they quickly trying to catch up behind Star & Stripe and Bakugo.
" I can sense some villains that have killing intent against heroes, innocent civilians, and don't regret their crime. Let's have a slaughter fest shall we." Ken and his group split up as they had to go to different area and it won't take long because of the amount of villains that they are trying to kill.
