Jayce

Jayce is the guardian of the seas, although he prefers to live above the sea. His last name was never confirmed, but many believe that he is Hot Rod's brother, meaning he is Nathan and Wriggle's son. Jayce is a very kind and passionate person, and doesn't like fighting. He has the ability to use and control any form of liquid, including blood. Jayce can also breathe underwater like a fish. Jayce actually can live off of water, and no food. His digestive system has become so used to water going in and out, he doesn't need food anymore.He seems to be the only person who enjoys having Tristepin (Sadlygrove) around. He and Tristepin have been friends for a very long time. Since before Tristepin's "death", Jayce has repeatedly fought against Tristepin's master, Goultard. Jayce's power rivals that of Don's, but the two have never met before. Jayce is called "Jay Jay" by Memoca, "Big Fish" by Tristepin, and "Big J" by Goultard.

Jayce has travelled all over the world, and has met Primus Doflamingo 3 times.
