A bull is an inact male of the species bos taurus (cattle); it is much more aggressive and muscular than the female of its species, the cow.

During a dueling competition in 1937, a wizard transformed himself into a bull, but was defeated by another wizard, who changed himself into a viper and bit the first wizard, thereby causing the bull-wizard to lose.

Behind the scenes

• In LEGO Harry Potter: Years 5-7, a bull was used to scare the Gringotts dragon instead of the Clankers.
