Finn White (Earth-5171)

Finn White was an Irish/American mob boss acting in Brooklyn, New York, as the leader of the Harlem Irish. When he tracked down the Punihser to kill him after the vigilante killed his son, he got his face disfigured by a shot of the Punisher with a handgun. Attempting to fix it, the numerous failed surgeries led to his face resembling that of a shark, inspiring him to name himself the Great White Shark, ready to have the entire underworld of the city into his control.
