Klunk

Klunk (occasionally spelled called Clunk) is an antagonist in Up Your Arsenal and the main antagonist in Secret Agent Clank. He is the evil counterpart of Clank who was created by Dr. Nefarious.

Klunk was originally created by Dr. Nefarious on planet Mariona to spy on the Q-Force by impersonating Clank. He impersonated Clank after Nefarious and Courtney Gears abducted Clank at the Holostar Studios. Klunk appeared to be identical to Clank in functionality, able to use the Heli-Pack, Thruster-Pack and transform into a giant form, and had normally red eyes which he could switch to green to fool Ratchet. After Nefarious was defeated, years later he was the mastermind behind the theft of the Eye of Infinity, though he was defeated by Clank and transformed into a vacuum cleaner.
