Funny how this seems harder to answer than "favorite legionnaire".
It's a toss-up between M'onel and Invisible Kid.
M'onel because of his personality, power and potential for great stories, given his history - but I don't think he's being used as well or as much as he could be in Legion stories. Always liked this tortured but noble hero routine.
Invisible Kid - again, personality, which seems pretty upbeat. He's willing to take risks, assume responsibility, he's smart and generally Mr. Nice Guy. He also has lots of story potential in him, with the espionage background. He's not one of the powerhouse members, but he compensates with his intellect. It would be interesting story-wise if the writers did give him a boyfriend but I don't think the character needs that to be interesting. Haven't seen much of him lately, so to speak....
