Cinna

Cinna runs for consulship in 87BC, on a platform that doesn't mention voting redistribution, though upon taking office he immediately pursues voting redistribution. He travels around Italy to gain support, with the result being the Senate declaring him a hostis (traitor). Marius returns from Italy and offers him his support; a civil war breaks out with the result that Marius and Cinna end up in power at Rome and have Sulla declared an enemy of the state, and both are "elected" consul the following year.

Marius dies of the flu very early on in the consulship; Sulla decides to return to Rome to restake his legitimacy yet again, so Cinna gathers his troops and sets out for Greece to meet him. His troops mutiny, and he's murdered before they even leave Italy, but the other consul takes charge and decides to wait for Sulla to arrive (these soldiers are very pro-Marius/anti-Sulla).
