Emzmuth is a Yaqualvan and the guardian who was sent, along with Albedo, by The Makers (El'sia and Ver'ena) to protect the Omnitrix (The Ancient Watch) with the bearer.

Albedo is a misunderstanding Galvan who is a guardian. Sometimes Albedo is being idiotically sarcastic when he gets around White People who are known as Paleskins, even when the White People are wielding muskets.
