Zaragamba, better known as Dolan's Mysterious Brother, is a member of the Planet Dolan crew. As his nickname implies, he is the older brother of Danger Dolan and is based upon Dolan's real life brother.
Dolan's Brother is an unidentified human-like creature who, as his nickname implies, closely resembles Dolan himself. Unlike Dolan, his brother has peach colored skin instead of white, and his eyes are yellow. He is also shown to have stubble across his face.
Dolan's Brother is a narrator for Planet Dolan and occasionally for Super Planet Dolan, where he provides factual answers. He is typically paired up with his younger brother and it is shown that they do not get along, frequently bickering amongst themselves.
