I know it's kind of late (it's 2025 now), but I haven't seen any other versions of the giant Apocalypse except for N64Mario's. He said he's not working on it, and it still needs a few minor fixes. I did add a new floor which I extended towards the screen. It is made to replace the "floor" sprite in the char's SFF. Here's the link if you anybody wants it:
I am going to fix the problem where he walks of the screen if you move behind him. His AI needs a little tweaking to get it to vary it's moves, and there is a sprite priority problem that covers characters with his body parts during certain moves(I don't remember which chars or which moves), other than that it's great! I would ask permission to post any altered character, but I will fix my own for starters.
PS, I know there is a patch for Apoc but it doesn't cover any of the issues I just mentioned.
