Overlord Glee is the main antagonist in the episode, So Totally Spaced Out, taking over Yugopotamia with his fluffy, cute army of Gigglepies.
Overlord Glee comes from the alien race of Gigglepies. Unlike the other Gigglepies, Overlord Glee is a colored white. Much like an actual rabbit, he has large floppy ears and feet, a small purple nose, and big shiny eyes. He has a crown antenna on his head and a crown necklace as well as a scepter to show that he is the leader of the Gigglepies.
Overlord Glee is the Gigglepie whom Timmy and his fairies were brought to when they attempted to rescue the Yugopotamians. Like all Gigglepies, he is a small, cuddly looking creature with a happy sounding name, but his true nature is that of an evil, vicious looking creature which he turns into when angered. He also talks in rhyme, much like the other Gigglepies. Shockingly, Overlord Glee has a cute side as well as a vicious-looking side to him. When he is happy, he looks like a regular, sweet, cream-colored little Gigglepie and has a high-pitched voice, but, when he is mad or feels threatened, he turns into a scarlet-red, scary, fanged rabbit with claws who talks in a rasp and murderous growl.
When Timmy, Cosmo, and Wanda were taken to him, Overlord Glee explains why he invaded Yugopotamia. He reveals that they move from planet to planet, draining each one and enslaving the natives in their goal to produce the Gigglepie merchandise. After Timmy questions their methods, Overlord Glee orders the other Gigglepies to attack Timmy (after he noted that their plan is horrible and that Glee didn't rhyme his sentences when he said that). He hypnotizes Cosmo and Wanda through rhyming, but fails at the moment when Timmy was in trouble and the last word that didn't rhyme. When Cosmo discovered that Gigglepies taste like manure, the Yugopotamians ate the Gigglepies (including Overlord Glee) since manure is considered a delicacy in Yugopotamia.
Overlord Glee's eyes are similar to those of the eyes of the Cartoon Network stars, The Powerpuff Girls. He is also voiced by Tara Strong, the voice of Bubbles in the original show.
