Martian Manhunter vs Terrax

1) No Tp.
2) Full-on Fight.
3) Everything goes, add Air Walker on Terrax's side.

Fight on the moon.

I would bet on J'onn in 1 or 2, but Terrax/Airwalker for 3.

Alone J'onn wins in 1 and 2. 3 not too sure.

I'd say he wins the first two by a decent spread, and he could win the third but it's probably a toss-up.
