Prime Minister Triter

The puppet leader of earth under the Illumidas Occupation Force, Triter wields no real power; he merely takes his orders from Supreme Commander Zeda, even if it means opposing his own people. He fears Harlock, and unsuccessfully seeks to coerce the former Federation captain into serving the new regime. In an utterly failed attempt to quell potential uprisings, he sentences Maya and Emeraldas to be executed by firing squad. When Zoll mounts a rescue attempt, the cowardly Triter shoots the Tokargan soldier in the back. He subsequently orders that Harlock be forever barred from returning to his homeland.

Though he does appear early in the SSX series, Triter's fate is never disclosed.
