Spotlight On... ISOLATIONIST!

[Dean Clayton]

Peter David resolves his own dangling plots! Introduced by PAD as an unnamed mystery villain in 1993 for the government-sponsored X-Factor, the Isolationist had to wait 14 years for his story to be picked up again during David's X-Factor Investigations run. A human somehow able to access to every active mutant power on the planet, Josef Huber found the weight of telepathy and multiple power sets a burden that drove him into isolation. Further cursed with a mental block that prevented him from directly killing a mutant, the Isolationist was forced to act through intermediaries on his quest to eliminate mutantkind and rid himself of his crippling powers
