- "No, we're still marching. But when we get there, we're going to visit a few old friends starting with Brutus and Cassius."
- —Julius Caesar on his future killers[src]
Brutus was a Senator of the Roman Republic and a friend of dictator Julius Caesar who, along with Cassius conspired and eventually killed him. He was later resurrected as an Encore, but was permanently slain by Bonnie.
Aberrant timeline: Julius Caesar knew that his friends, Brutus and Cassius, would eventually play a pivotal role in the conspiracy to kill him due to owning a Rise of Rome book from the future which he stole from Nate Heywood. After marching to Rome and winning the civil war with his legion, Caesar killed both Brutus and Cassius.
Current timeline: When the timeline was restored by the Time Bureau and the Legends, on March 15, the day known as the Ides of March, 44 BC, the Senate, led by Brutus and Cassius, conspired against Caesar and killed him at the Theatre of Pompey.
After his death, he went to Hell and his soul was claimed by Astra Logue. However, it was later stolen by Lachesis, who resurrected and sent Brutus to retrieve a fragment of the Loom of Fate in exchange for freedom in resurrection. Despite attempting to form alliances with everyone else looking for the Loom fragment, Brutus was ironically back-stabbed and permanently killed by Bonnie for his trust. He died begging for mercy.
- Political influence: As a Roman politician, Brutus had enough political influence among the Senate to conspire and eventually kill Julius Caesar.
- Pugio: Brutus owned a dagger with which he proceeded to personally stab Caesar. After being resurrected as an Encore he wielded a Hell pugio.

Behind the scenes
- In the real world, Marcus Junius Brutus was indeed a Roman politician who conspired and proceeded with the killing of Julius Caesar, being his best friend as well. He was also a brother-in-law of Cassius, another conspirer and killer mentioned by Caesar in the series.
- Nate Heywood saying "Et tu, Sara?" to Sara Lance is a reference to "Et tu, Brutus?", uttered by the dying Julius Caesar in William Shakespeare's play Julius Caesar as he noticed that Brutus was involved in his stabbing.
