In variants of this timeline, Franklin and Rachel give birth to the nigh-unstoppable villain Hyperstorm, a mutant who is capable of drawing virtually limitless energy from Hyperspace itself.

Another child Franklin fathers with Rachel ( in a reality that only slightly diverges from Earth-811 ) is known as Dream Summers.

Dream, a mutant like her parents, demonstrates telepathy / empathy.
