Marcus Junius Brutus

Marcus Junius Brutus (early June 85 BC – late October 42 BC), often referred to simply as Brutus, was a politician of the late Roman Republic. He is best known in modern times for taking a leading role in the assassination conspiracy against Julius Caesar.

The dagger he used to assassinate Julius can be obtained in Assassin's Creed: Brotherhood along with his personal armor, which is the most powerful in the game. It is unlocked once you explore all the ruins in which the Followers of Romulus operate. Note that it has 25 health diamonds, the same as Altair's Armor in the second game, it cannot be broken, and it cant be dyed, also similar to Altair's Armor.
