Prince Sprocket was the younger son of King Mondo and Queen Machina, and the brother of Princess Circuitrina. Like his sister, he was spoiled by his parents and liked to play, often with the Rangers. Sprocket also had a jealous and devious side, once trying to get his brother Prince Gasket destroyed by the Power Rangers. A running gag is that whenever Klank and/or Orbus tried to suggest a plan, Sprocket would interrupt them and take credit for it. Any attempt on their part to insist the plan was their own thought would be often shot down by Mondo. When the plan later failed Sprocket would renounce ownership by blaming it on Klank and, oftentimes, his sister (his father would scold him for the latter, however). He was almost blown up by Lord Zedd at the end of Power Rangers Zeo: Revisited,
