When first seen, it takes the appearance of a dark mysterious man who wears a trench coat and hat covering the eyes. After a fight with Max, its true form was revealed to be a tall black humanoid robot after its ID Mask was destroyed.
As a mechanical being, it has no care or remorse for beings who are alive, such as when it told Max that draining Verdona's life would kill her just like its race's organic creators. It also justifies the act by saying it is vital to the continued survival of its race.
The Synthroid appeared in Moonstruck, where it was trying to capture Verdona so she could be used as a power source for its planet. Max rescues Verdona and shoots a part of the Synthroid's ship, causing a massive explosion that destroyed the Synthroid itself.
