Sledge was a large hammerhead shark that was part of Barkley's Ghostfins, along with his friend Peen. He joined the Ghostfins after being convinced that Finnivus was evil. He only stopped hating having to sneak around after being beaten in the greenie by Barkley, along with the other nine original ghostfins that Barkley trained. Sledge fought well during battle but suffered from severe burns after the attack on Riptide.


  • Sledge's name is a play-on word for Sledgehammer since he is a Hammerhead shark and a sledgehammer is a real hammer.
  • His name may also be a reference to Eugene Sledge, author of the WWII memoir With the Old Breed at Peleliu and Okinawa.
