Flex

Flex is a shapeshifting hero who's physical form seems to be made up out of an organic material with the same properties as Vulcanized Rubber.

Backstory
Richard Armstrong Dibney was born with his metahuman abilities due his parent's involvement in the super-science group known as The Explorers of the Unknown. Particularly the source of this mutation was likely an interdimensional trip his mother took before knowing she was pregnant.

Early Life and Childhood
Due to a combination of the oddness of his parents work requiring them to live and work outside of major populated areas (due to a government mandate) and the...less than normal appearance their young son had, Flex's parents made the decision to more or less raise him in private at one of the Explorers of the Unknown's complexes.

College and Heroics
In the most recent part of his life Flex has become a student at Vanderburg University and began using his not insignificant superhuman abilities as a hero not long after the New Champions officially formed. He was one of the earliest recruits beyond the initial group.
