Haven't seen anyone else do this, so why not. (Low effort)
Shinjuku's strongest: literally just strongest of today. Just a better gojo. Using special on the ground activates infinity, and using it in the air does... something? Idk. It has an animation. Has a full ult. (USING HOLLOW NUKE WASTES YOUR ULT, ONLY DO IT AT THE END)
The dragon: ...same as Shinjuku's strongest. (Could be bugged?)
Overworked assassin: some sword guy? Idk what he's from. Has an unfinished ult. Using it just makes you do a lil dance and heal. His special is just a slice and I THINK it makes you move faster. Not sure tho.
Pure evil (i think? I fogor the name): DIOOOOOOO!! Idk what his ult is because I died before I could use it :( its called THE WORLD so it presumably just stops time / stuns everyone. His dash does a weird thing where you tp forward WAY too far. I never hit it. His special is just a counter that stuns.
