I'm sorry if this question seems completely retarded to comic book friends, but please forgive me since my world revolves around mangas and animes. Anyways, I've read both Jean grey's and Mr. Manhattan's descriptions. Both apparently have infinite amount of energy, have control over material down to atomic, or subatomic level (in other words, manipulate, change, or create any material), and teleport themselves (jean grey can open portals in comic book and mr manhattan can teleport). The only difference I can see is that mr manhattan can see into the future and regenerate his body and has no "perception of time," while Jean grey is a telepath and overpowered enough to have the comic book editors to force the creators to kill her off the story line. So who's exactly stronger?
