Graviton
Super Name: Graviton
Real Name: Franklin Hall
Nickname: Dr. Hall
Universes: Earth-616
Franklin Hall was born far North in Alberta, Canada. He excelled at school his entire life, especially showing promise in the sciences. He eventually became a lead scientist, considered by many to be the most brilliant, at a small private physics research institute in the Canadian Rockies.

During an experiment on particle acceleration, Hall attempted to align a particular set of graviton matrices and induce a teleportation effect. All he succeeded in doing however was overloading the power thresholds on his equipment. The resulting explosion destroyed Hall's equipment along with two neighboring particle accelerators. The mixture of these explosions resulted in an atomic flurry that intermingled Hall's molecules with sub-nuclear graviton particles eventually granting him the power to mentally manipulate gravity.

Franklin, at first, hid this power from the world. Thinking that outsiders would view him as a freak, he attempted his best to mask his immense superhuman ability. However, it wasn't long at all before his will broke and Hall was using his gravitational abilities to gain whatever he wanted. Much to his joy, people began to fear him and being a man of drive and resource he quickly fashioned himself an elaborate costume and took on the name Graviton.
