Attendants are beings who serve various deities. They have a variety of duties ranging from assisting their deity, teaching them, or keeping them in check.
List of Attendants
Mr. Popo is an attendant who serves the long lines of Guardians of Earth at The Lookout. He works as a groundskeeper and as a body guard to test in physical ability if anyone is worthy of seeking an audience with the guardian of Earth.
God of Destruction attendants
All of the Gods of Destruction are shown with an attendant following them. Whis is the attendant to Beerus, the God of Destruction for Universe 7, while Vados is the attendant for Champa the God of Destruction for Universe 6.
These attendants serve as martial art teachers to their Gods of Destruction, and are physically stronger than the Gods. They are tasked with keeping the Gods of Destruction in check, and will intervene when the God goes too far. They also perform trivial duties for the Gods of Destruction such as preparing meals for them.
All of the attendants seen in the anime are Angels, watching over their respective God of Destruction, if the God of Destruction were to die they will cease to function until the next God appears.
