Dr. Gavin DeMarco was the lead researcher at Brighton Medical Facility.
Gavin DeMarco was working on genetically modifying sharks to make them more vicious and invincible, along with a team consisting of May Huang, Shults and two 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 into a shark-man. Some months later, DeMarco was approached by Shay late one night, being mauled by him.
