I did very much enjoy the Juggernaut's first appearance (origin) story --- this slow, unstoppable, plodding menace that was attacking the X-men's mansion. The big reveal that Prof X had a brother (who was a jerk), and the way the X-men figured out to stop him.
"Mind you, I am not saying Juggernaut is "bad". Just that I don't care for the character."

Oh, that's easy. Just change the character into someone else. Maybe he's really Logan's brother possessed by a demon spirit or something.
Yes, I'm being sarcastic. But what a novel idea to simply, you know, NOT write a character you don't care for instead of radically changing who they are.
I believe that Jahf has super strength, nigh-unto type invulnerability, and - I think all the I.G. have devices that allow them to fly. Flight boots, jet belts - somethin' or other that Mr. Byrne mentioned.
His smile as he dives into bare space, returning to Earth is fun. "That's for sure" smile is what I see - great call back!
Gonna miss Guardian, but I believe we've seen plenty of the I.G. lately. Surely it's Mr. Byrne's decision, but I don't suspect that we're gonna see them again any time really soon.
