This weekend at Heroes & Villains Fan Fest, David Ramsey (portrays John Diggle on Arrow) confirmed that King Shark will appear in the upcoming two-part The Flash and Arrow crossover event.

"Because we are going to be tracking down a particular member of the Suicide Squad that so happens to be a 14-foot shark," Ramsey revealed to those attending the show's panel at the San Jose Convention Center.

King Shark made his unexpected debut in the closing minutes of the "Fury of Firestorm" episode of The Flash this season. He was yet another Earth-2 baddie that Zoom sent through the breach to kill The Flash/Barry Allen (Grant Gustin). He had The Flash in his clutches, but was incapacitated by Earth-2's Harrison Wells.

PART ONE OF THE EPIC CROSSOVER WITH “ARROW” — In its second major crossover event with “Arrow,” Vandal Savage (guest star Casper Crump) arrives in Central City and sets his sights on Kendra Saunders (guest star Ciara Renée). After Vandal attacks Kendra and Cisco (Carlos Valdes), they turn to Barry (Grant Gustin) for help. Realizing how dangerous Vandal is, Barry takes Kendra to Star City and asks Oliver and team to hide her until he can figure out how to stop Vandal. However, things quickly go from bad to worse when a man with wings AKA Hawkman (guest star Falk Hentschel) shows up and flies off with Kendra. Meanwhile, Harrison (Tom Cavanagh) develops a serum to make Barry run faster and asks Jay (guest star Teddy Sears) to test it out. Ralph Hemecker directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Aaron Helbing & Todd Helbing (#208). Original airdate 12/1/2015.
