nah, too weak. that titles reserved for the creme de la creme. he may not be able to be killed (supposively) but he can easily be beaten. he'd have to have some serious untapped potential like Elixir to warrant being called that.
but speaking of the GLA, i'd say Squirell Girls an omega level mutant.
Mister Immortal is not considered a powerful mutant in general. But he will out live every single character in the Marvel Universe. He should at least get an honorable mention when it comes to omega level mutants. What do you think?
