Thor vs Martian Manhunter-To the Death

Both characters are actively trying to kill the other, and will use any means to do it, including fighting out of character. Who wins?

Most will say MM because of his telepathy. In this case Thor is in the same boat as Superman, both incredibly powerful but susceptible to mind attacks. Anyway, I believe, like Supes, it can go either way.

Martian Manhunter phases his hand through Thor's head at breakneck speed.
