Shockwave is part of a group of Shang-Chi’s enemies that includes Razor Fist, Shen Kuei, Death-Hand, Shadow Stalker, Tiger-Claw and led by Shang-Chi’s adoptive brother Midnight Sun that ambushes the Master of Kung Fu and Domino while the two are on a date in Hong Kong.  Shockwave is defeated after one of his shocks aimed for Domino misses and hits Shadow-Stalker, whose flail is deflected off of a serving tray thrown by Domino and hits Shockwave in the face, knocking him out.
