Whis is one of the Grand Minister's angel children. He is assigned as the attendant to Beerus, Universe 7's God of Destruction. He is also Beerus' martial arts master and one of the most powerful characters in the series. He has a wealth of secret techniques under his belt, including time travel and the mysterious Ultra Instinct.
Whis typically maintains an aloof demeanor and prefers to keep his hands clean, not involving himself in most situations. However, he has a weakness for food, particularly if it comes from Earth. Even angels can't resist the allure of ice cream.
