Brazen Bull is a Fire/Dark type. The name is the same as a torture device called the Brazen Bull. The Fire type is both because of the blaze breed Tauros and where Brazen Bull gets its name, the Dark type is because the minotaur myth takes place in a maze that is usually depicted as very dark and the Brazen Bull torture device has you put the person inside it.
This was mostly an excuse to make a minotauros but I think it's pretty cool.
