A Rottweiler, and one of Bitch's original three dogs. He was killed in the Leviathan arc, along with Judas. Bitch scratched his name onto the Endbringer Fight Memorial to remember him and his sacrifice.
A well-trained attack dog, Brutus is the first or second dog Bitch trained to use her power on, and the second or third dog she massively increased in size.
Brutus is the narrator for an interlude in which Bitch breaks up a dogfighting ring run by Empire 88. He knows a lot of commands and is able to tell how angry Bitch is by how much she uses the F-word.
