Dr. Franklin Hall, in the comics at least, was actually the supervillain 'Graviton'! After am experiment caused graviton particles to merge with his own molecules, Hall later discovered that he could mentally control gravity. He eventually turns to crime, donning a costume and adopting the above alias. Will this version of the character follow suit?

Ian Hart will play? We know it's a scientist!
