The original character notes connect Striker with the US Marine Corps and a catastrophe during his third tour in Vietnam. Afterwards he exists as a man of large matches, still able to speak, perceive his surroundings and handle objects. Rumours of magic surround a transformation whose full circumstances remain unexplained.

Striker receives distress signals, directs Matchman and keeps the team coordinated. In “Day of Discordia,” he wakes Scott through his watch and teases him about his feelings for their enemy. Scott’s reply indicates that Striker no longer needs sleep, although the sergeant does not regard night duty as a pleasure.

In the feature screenplay, he exchanges intelligence with Suzanne, assembles a rescue team and joins the mission himself. In “Aileen Alien,” he confirms her warning and helps organise cooperation with B.L.A.H. Quick decisions make him indispensable, while fear of fire remains a serious vulnerability.
