He was supposed to play an important role in Season 3 , being related to one of the main four characters in a major way. However, since Wander Over Yonder has been cancelled and will not have a Season 3, he never appeared again and was of no importance.
- The Waste of Time (no lines)
- It has been theorized that Monkeyboy is Lord Hater, considering that their heads both look the same, and that Lord Hater used to be organic.
- The creators have also teased this, reminding the fans that characters can go by multiple names.
- At the end of credits from The End of the Galaxy when Dominator leaves the galaxy, there is a damaged NASA-like spacecraft from which green lightning crackles. The sound of a monkey screeching can be heard which blends into Hater's laughter. This implies that Hater is Monkeyboy, and also foreshadows Hater's backstory in season 3.
