Alessio was a terran who served under Cliff Nadaner after the Brood War, striking against the Terran Dominion. He did this alongside his twin Peter-Michael, whom he secretly hated but never did anything apart from.

Alessio was killed on Tyrador VIII by a Dominion ghost via the use of psionic powers.
