Martian Manhunter, because of superior telepathy and other additional Bonus abilities.

Martian manhunter have almost every power I can think of..

So yeah, I vote for martian

Martian Manhunter slaps.

Martian Manhunter would whoop her and then celebrate with a party on Mars

And then destroy Tamaran

People read Martian Manhunter’s power set and think, “Oh, in theory he is so incredibly powerful that he must obviously pwn every foe he could come across.” But like, J’onn gets his butt kicked...all the time. With Starfire’s powers being heat-based and her incredibly advanced combat prowess, Kory has a shot here. Of course, like most hypothetical matchups, there are scenarios wherein each party could come out on top, meaning there’s no definitive answer.

J’onn stomps,Kori is powerful yeah but she isn’t even in the same league. J’onn is on equal terms with the likes of Superman and Wonder Woman. His weakness to fire is only physiologically,Starfires heat blasts aren’t even fire so they wouldn’t even phase him. His telepathy could also easily fry Koris mind.
