Fenix is a zealot hero unit that appears in "First Strike" and "Into the Flames." Fenix uses the same attack as a normal zealot but deals more than twice as much damage, and has significantly higher HP and shields. He already beats the Leg Enhancements upgraded, greatly increasing his movement speed. With his high attack power he can kill zerglings in one hit and hydralisks in two with a weapons upgrade. Despite his high power, the player must take care not to lose him amidst their other zealots and retreat him if Fenix takes too much damage.
