Marcus Andronicus is a Tribune of the People, Publius’s father, and Titus’s younger brother, the political face of the powerful Andronicus family.
He announces and approves the nomination of his brother as Emperor, but accepts it when Titus chooses not to take the opportunity. He is appalled at Titus’s killing of Mutius and his refusal to let him be honorably buried. He attempts to make Titus somewhat more flexible, though he is not overly successful at this. He loves his niece Lavinia and is horrified when he finds her mutilated; as further blows fall on the family, he is brought to the edge of despair. He recovers somewhat, and is able to work out a way to communicate with Lavinia. He is probably the most intelligent of the Andronici, though this does not do him much good. He does what he can to control Titus when the latter essentially loses his mind, but does not in any way contradict him. He arranges for the meeting at Titus’s house and plays the honest broker at the feast. How much he knows of Titus’s plans for this meal is unknown, as he misses the murder of Chiron and Demetrius. Still, after everyone is dead, Marcus is finally able to get a family member named Emperor of Rome.
