Juggernaut had a run with the X-Men for awhile before moving to Europe and becoming a member of Excalibur for some time. He was interesting during the Marvel/Malibu crossovers too when put against Prime, and generally just trashing the other universe. During that period a lot of characters crossed over and Juggy and other Mutant Liberation Front members joined a couple random Malibu villains to become the Exiles. Black Knight lead the then current incarnation of Ultra Force as well with his light saber like sword. IT WAS A WEIRD TIME.

Always liked seeing Jugs vs Hulk too, since he was one of the only characters physically capable of dealing with Hulk at his peak.
