AND maybe even Image. The Spectre, Phantom Stranger, Parallax, Krona, all of the Green Lanterns, Flash, Guardians, etc. Marvel is a MUCH weaker universe. And I hear that Spawn has gotten quite powerful as well. And how is Rick Jones on the same level as any of those guys? Franklin being a reality warper is cool, not do to his powers or anything, but the fact that he's one of the most powerful mutants and he's about 12. That's an interesting concept.
It's not Franklin so much as a character as it is the way he is treated by the Marvel writers. He should be a young adult by now and used in more interesting ways.
