Steamborg is a minor antagonist in The Bedbug Man and the Opossum Boy, appearing as the main antagonist of the episodes "Glory Days" and "Let's Take A Moment". He is an evil robot that is obsessed with destroying the superhero team P.O.I.N.T. and anybody associated with it.
After Fox Tail, Laserblast and Doctor Greyman leave on a secret mission, Steamborg attacks P.O.I.N.T. headquarters by reaching through the roof and grabbing the Junior P.O.I.N.T. members; Silver Spark (Carol), El Bow (Mr. Gar) and Rippy Roo. As Steamborg approaches them, Carol takes out P.O.I.N.T.'s case files and states that the robot's design is similar to that of the ones built by the villain Doctor Weakpoint.
While Carol holds the robot back, Mr. Gar, taking note of what she said, goes after the pink core in the center of Steamborg's body, although it slaps him away before he can hit it. Realizing that going directly for the robot's weak point isn't going to work, Carol topples the robot, making it's body fall apart, and Gar goes after the pink orb, although Steamborg reforms it's body and slaps him away again. Steamborg attempts to blast the Junior P.O.I.N.T. members with a laser, although they manage to avoid it.
Forming a plan, Rippy distracts Steamborg, allowing Gar and Carol to break apart his body. Rippy then traps the pieces of Steamborg's body inside of his pouch, leaving all but the core behind. Carol questions if there is a point in destroying the core if the rest of the robot's body is trapped, however, Steamborg's arm reaches out of Rippy's pouch and tries to grab Carol and Gar, resulting in them smashing the orb to pieces, destroying Steamborg. Immediately afterwords, Fox Tail, Laserblast and Doctor Greyman then return from their mission and observe the remnants of Steamborg. Seeing how well the Junior members handled Steamborg, Fox Tail, Laserblast and Doctor Greyman deem them capable enough to be considered full time members. Carol would later take Steamborg's eye as a trophy after she left P.O.I.N.T.
