Caesar

 is a former Follower of the Apocalypse and the charismatic and cunning leader of Caesar's Legion.

The legionnaires are a well-organized fighting force and absolutely merciless in their slavery. Mimicking the ancient traditions of the Roman Empire, the legionnaires dress in segmented football pad armor and decorated football helmets. Caesar attempted to destroy NCR’s presence in the east, and actually succeeded in destroying one of their major fortifications, Fort Aradesh. When Caesar attempted to take Hoover Dam, however, the legion was badly defeated. Since that time, Caesar has moved east of Texas, past the legendary cyclones that rage for most of the months of the year.

Caesar also:
 * is merciless, which is proved with Graham's execution,
 * is admiring ancient Rome.

Appearances
Caesar's Legion was initially (when Chris Avellone still worked on the project) to play a significant role in Van Buren (Black Isle's Fallout 3), but they were mostly cut out because the game was getting too big, although they had some minor appearances in the game. Black Isle planned to give them a major role to play in Fallout 4. The Legion will appear in Fallout: New Vegas, but Caesar himself might be present.

Behind the scenes
Metzger, the leader of the Slavers Guild from the Den, was initially named Caesar.
