Whis is the Guide Angel Attendant and martial arts teacher of Beerus. Whis, due to his background, is very calm and collected. He is also very knowledgeable and wise. Whis is too calm even in the face of danger.
He only loses his calm in the face of food. He likes eating a lot, the same as Beerus, and has become fond of Bulma because she keeps feeding him.
