Notes

• Despite Motormaster's instructions and bio both identifying his ranged weapon as a cyclone gun, for some reason his Universe profile states that he's equipped with an atom-smasher cannon instead. Menasor's profile, however, states that he uses Motormaster's cyclone gun.
• By the time of Dreamwave's More than Meets the Eye series, the atom-smasher cannon had been downgraded to an atom-smasher rifle for both Motormaster and Menasor.
