Sente was a cybernetic metahuman (death-vision) sent from the future to destroy the Meta Board League before it began.
Sente was created several decades in the future by one of the MBL's oldest enemies, who programmed him with detailed plans to gain the MBL's trust and then destroy the team at precisely the correct moment, then rule the world. He was sent back to the year 1999, where he ambushed a metahero named Freebooter and killed him. He then replaced him at a meeting of metaheroes organized by Meta 7. His plans were discovered by Exile, a telepathic metahuman, and he was forced to assist the team on its mission to Antarctica to stop an invasion of the extraterrestrial Basilisks and retrieve a starship there. During the mission, he experienced doubts about his programming. Sente was killed during a battle with the Basilisks when he was shot in head by a stray bullet.
