Fiction

Marvel Comics continuity

Triton appeared exclusively in the UK portion of the Marvel Comics continuity.

In the 25th Century, Triton infiltrated the Autobot ranks for a period of ninety years, during which time he passed secrets back to the Decepticons.

In the year 2510, Triton was present when Rodimus Prime announced that the last remnants of the Decepticons had been destroyed. Unwilling to allow the Autobots to win the war, Triton objected to Springer being chosen as Rodimus Prime's successor and instead put forward Ultra Magnus as a potential leader.

In the ensuing debate, Triton encouraged the Autobots to quarrel, until Scattershot killed Roadbuster after the latter threatened Triton’s life. Sandstorm, furious at Roadbuster’s death, killed Triton in revenge for causing all the trouble in the first place. Triton died as the Autobots dissolved into a new civil war. Peace

Triton was later forced to become part of Squadron X, a team of Decepticons which served as a brutal counterpart to the Autobots' Wreckers, when he gained notoriety for annihilating a 20-strong Autobot boarding party. Triton's Squadron X profile In Squadron X, Triton made a friend in Crosscut when the two were welded together by Springer in battle. Crosscut's Squadron X profile The Wreckers and Squadron X's rivalry came to a head on Pova, but after being dispatched in battle, he and the rest of Squadron X were rounded up in a containment unit and put in inhibitor harnesses.

According to Fisitron's Wreckers: Declassified datalogs, Triton and the other members of Squadron X were able to somehow escape their harnesses, forcing the Wreckers to execute rather than imprison them. However, this may not be the full story. Last Stand of the Wreckers #4

Turns out it isn't. Squadron X was to be freed due to the violation of Pova's neutrality act, but Impactor killed them all instead. Last Stand of the Wreckers #5
