Last man standing

Iron Man Vs Aquaman (classic) Vs Cyborg(JLA) Vs Namor .......who wins? No prep

Is Iron Man protected from telepathy? If not, Aquaman. If so, Iron Man probably has sonics or something that could take down the others (not real up to date on Cyborg though admittedly).

Iron Man has psi-blockers, yes.

IMPERIUS REX!

Yeah, probably Namor

If anywhere near water Namor wins.
