Exxorian monkeys

Exxorian monkeys are a race of alien space monkeys featured in media based on concepts developed by DC Comics. One such monkey of note, Gleek, featured in the Super Friends animated franchise produced by Hanna-Barbera Productions as well as the Super Friends comic book series by DC Comics. The character was first introduced in "The Brain Machine", which was the first segment from episode 1x01 of The All-New Super Friends Hour in 1977. He was voiced by actor Frank Welker in the series.

They're basically just purple little monkeys with limited intelligence and long tails.
