5 people to save the world.

[Slamz]

You don't have any immortals other than hulk on that team, a majority of the god like entities people have been stacking their teams with could wipe out your top 4.

The Hulk is immortal? Huh. Did not know. Granted I never read the comics. Is he literally unkillable or he just doesn't age? (They call the Highlanders immortal but you can still chop off their heads to kill them.)

Zouji's team has the advantage of not being full of disinterested or evil parties who would cause the world more harm than good. :-p

Granted Magneto is not exactly a good guy but if the world was threatened, you know he'd have to save it, if only because the threat would foil his grander plans.
