King Shark (Arrowverse)

King Shark is an antagonist in the second season of The Flash. He hails from Earth-2 and was sent by Zoom to kill Barry Allen.

His voice was provided by David Hayter, who is famous for providing the voices of the characters Solid Snake and Big Boss in the Metal Gear video game series.

History
King Shark is first mentioned in the episode The Fury of Firestorm, where Officer Patty Spivot finds shark teeth in an alley in Central City. She also claims that a witness saw a shark walking on land. She belives that it is a meta-human and Barry tests the teeth to find only human DNA, disproving the idea of a man-shark.

However, King Shark is shown to be real when he attacks the Flash, who had been watching Spivot sitting in a café. Claiming that Zoom wants Barry dead, King Shark intended to kill Barry but was stopped when Spivot, who had left the cafe by then, sees him. Drawing her gun Spivot tells King Shark to yield but he only laughs. He throws Barry aside and advances on to Spivot. Though Spivot shoots at him multiple times King Shark shows no sign of injury and is only defeated when he is shot in the back with an energy weapon by a hooded man who is revealed to be Earth-2's Harrison Wells.
