Klank is one of the top two robots that serve the Royal House of Gadgetry. Klank is a humanoid robot, while Orbus is more of a cute-looking module. They serve as the monster enlargers of the Zeo arc, and are often kicked around by their masters. When King Mondo wanted to have his machine/monsters grown to megazord size, Klank was given an upgrade to allow him flexibility to swing Orbus around until he built enough momentum to toss him at the monster in need of enlarging. Klank has a rather thickScottish burr for a mechanical background. He is also quite pompous and thinks highly of himself. He serves his masters with fierce loyalty, but never inserted himself physically into battle. More often than not, Klank would come up with a plan to defeat the rangers or take over Earth, only for Sprocket to immediately take credit for it. Whenever he tried to insist that the plan was his idea, his master would immediately silence him. Once the plan failed Sprocket and Mondo would then quickly blame Klank for coming up with it. Both Klank and Orbus are presumably destroyed by Zordon's Energy Wave in Countdown to Destruction.
