Colin Phash is a young terran child and the son of former Senator Corbin Phash of the Terran Dominion. He has psionic powers which can be used to kill zerglings and is good at hide and seek. His powers include a "quiet voice" which prevents the zerg from detecting him, but it requires concentration. Phash became a trainee at the Ghost Academy. He was later freed and became a Umojan Protectorate shadowguard.
