Prince Sprocket is the son of King Mondo and Queen Machina who seems to get nothing right. Sprocket, along with the rest of the Machine Empire, journeyed to the Moon from where they planned to stage their invasion of Earth. Sprocket often helped his father think of plans to take down the Power Rangers and though he was a spoiled brat, he was still a considerable opponent. As a bumbling spoiled brat, he is often made a fool of by the Zeo Rangers. He shares his parents' hate for the Zeo Rangers, but his attempts to defeat them are usually foiled because of his stupidity (and likely his naivete due to his youth).
He was upset when his older brother, Prince Gasket, returned meaning he wouldn't become the King of the Machine Empire. Sprocket later tried to get rid of Gasket after he returned for the second time by tricking him into growing giant to fight the Power Rangers. But this plan failed and his older brother almost gave him his what for, until King Mondo showed up and drove him away. Sprocket was blown up along with the rest of the Royal House of Gadgetry but was repaired by the United Alliance of Evil and attended the alliance's meeting on the Cimmerian Planet. Prince Sprocket took part in Dark Specter's assault on the universe, however he wasn't seen during Zordon's energy wave. It is assumed he was either destroyed or purified.
- Sprocket was the first child like villain in Power Rangers.
- His Super Sentai counterpart, Buldont, is the same one as Gasket's since in Chouriki Sentai Ohranger, Gasket was an older version of Sprocket.
