Commander Peepers is Lord Hater's number one henchman and the secondary antagonist from the show Wander Over Yonder. He is voiced by Tom Kenny.
- Peepers is Hater's second-in-command and leader of his army of Watchdogs.
Peepers is a small creature with a large eye for a head with a red/purple iris. He has a lightning bolt mark on his black uniform and wears red gloves and shoes. He greatly resembles the Watchdogs, however he outranks them by the pointed helmet on his head which the Watchdogs lack.
While Peepers lacks in size, he makes up for in loyalty to his boss, Lord Hater, and determination to destroy the only threat to the Hater Empire, Wander and Sylvia. Peepers seems able to hold an impressive grudge, second only to Lord Hater's contempt of Wander. Peepers is both under-appreciated by the overlord and overworked.
- Peepers is voiced by Tom Kenny, who did voice work for Craig McCracken's previous projects The Powerpuff Girls and Foster's Home For Imaginary Friends. He is most famous for the voice for SpongeBob SquarePants and also voices the Ice King in Adventure Time.
