Biography
Gavin DeMarco was working on genetically modifying sharks to make them more vicious and invincible, along with a team of May Huang and three others. However, on December 11, 2013, the S.T.A.R. Labs particle accelerator exploded, causing a shockwave that transformed one of their patients, Shay Lamden, who had been using their shark DNA to develop regenerative cells, transforming him in to a shark-man. Some months later, DeMarco was approached by Shay late one night, being mauled by him.
