Mechanikat is the main villain in the American animated series Krypto the Superdog. He is a mechanical cat who constantly comes up with schemes to conquer Earth.

Despite being the main antagonist, he rarely acts upon the role, and often sends machines or other antagonists to face Krypto. His sidekick is his agent Snooky Wookums. In his final appearance, Mechanikat upgrades himself and transforms into Mega Mechanikat and tries to lure Krypto to a planet filled with krypton. Since krypotine was Krypto's weakness it would've killed him. He was voiced by Maurice LaMarche.
