- "Around, and around, and away we go!"
- ―Klank's command for Orbus to enlarge a monster[src]
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 thick Scottish burr for a mechanical background (for unexplored reasons).
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, however, 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.
- During various encounters with the Zeo Rangers, Klank seemed to show a lot of care for certain monsters that King Mondo and Queen Machina sent to Earth. A good example is Somnibot (whom Klank and Orbus themselves assembled), who was sent to put the Rangers to sleep after teams of Cogs were wearing them down for two weeks. This is in complete contrast with Acha, who called Somnibot's parallel counterpart "the worthless robot" and only valued him (monster was male in Ohranger) when he excelled at his destruction.
- Klank is voiced by Oliver Page, who went on to play the role of a minor character in the blockbuster film Titanic.
- Klank's US costume looked of noticeably different (and poorer) quality to his Japanese counterpart, apparently being made of foam.
- While Orbus was frequently seen floating in Ohranger footage, he never did so in US shots and was almost always carried or fixed to Klank's shoulder. Also, while Kocha could move his head and open his mouth in Ohranger, the prop used in Power Rangers appeared to be one solid piece that was incapable of any kind of movement at all, similar to Somnibot's mouth.
