Background

Hubert and Pinky Fusser were twins. Both born with dwarfism, one became a nuclear scientist, and one became janitor at the same privately-owned research corporation where his brother worked.

When an accident strikes Hubert (the scientist), his brother Pinky rushes to assist. The resulting radiation causes them to become one, a Fusion - a twin-headed radioactive being which contains both of their personalities.

As Fusion, Hubert wishes to persue plans for extraordinary research which are not in the best interests of humanity. Pinky, however, wants an end to the madness. The final result is their eventual separation at the hands of Spider-Man.
