The Jaspers Warp refers to the vast destruction of space/time caused in the aftermath of the Marvel UK cosmic villain, Mad Jim Jaspers, alteration of London and his defeat by Captain Britain. It resulted in the formation of several extremely deformed and unstable mutant children, known as "Warpies" and also had severe detrimental effects on reality itself - much like the ripples of a lake, it would take many years for Jaspers Warp to clear, even after the destruction of the mad mutant.
