You know, considering the amount of villains in Wander Over Yonder, having one of the two kill-bots show up in this as a possible "significant antagonist" is a little strange...
Perhaps kill-bots ARE more significant in season three? We do know Wander and Hater get hunted down, after all...
In this cover of “I’m Finally Me” from ZOMBIES 3, Disney TVA's animated villains gather together to sing a power anthem about how good it is to be evil. “Evil As Can Be” features Darcy and King Andrias from Amphibia, Glomgold from DuckTales, Dr. Doofenshmirtz from Phineas and Ferb, and Lord Hater and Killbot 86 from Wander Over Yonder.
