Rick (played by Kevin Castro) is an alien in human form and former warrior for Nimbar. He is cold, distant, and after being the sole survivor of his destroyed planet, he is full of anger toward Nimbar and the other guardians. He holds the power of Orion which he uses on the fourth transo disc when Laurie is unable to fight. His name is too complicated for humans to speak so he insists that Nimbar call him "Rick". His suit is silver and his fellow Sentinels were Leo, Draco, and Ursa who were badly defeated by Predaraptor.
