Late reply but whatever.
Assuming you can't kill, dismember, disintegrate or even "throw him really far away"...
Wouldn't say these are my favorites but they're the first that came to mind:
-Joshua
-Josuke
-Deku
-Greed
-Cu Chulainn
Deku would try to form a plan to escape by watching the machete man's(I'm gonna call him Bob for simplicity's sake) movements.
Greed could just make himself invulnerable with his Perfect Shield.
Josuke could easily hold him off because Bob wouldn't be able to see nor harm Crazy Diamond. Alternatively, he could also trap Bob by restoring a wall around him, assuming Bob doesn't have super-human strenght to break out.
Joshua takes it as a high-stakes game but he can also easily dodge Bob's attacks.
Cu dies because Bob isn't human
By default, Greed survives because Bob can't hurt him.
Josuke has the second best chance to "defeat" Bob but only if he can hold him with Crazy Diamond or trap him between the restored walls.
Deku can survive by devising some sort of plan, dunno what, would depend on the environment and if there's nothing he can work with, his best shot is at outrunning Bob.
Joshua leaves everything up to luck on a coin toss because he's an absolute madman.
Cu dies.
You sure about that?
Think again. He now wins by default because there's no machete man to kill him.
