Otho

Otho runs the Legion arena at The Fort $$

Background
Not much is known about Otho, other than his sexism, which stems from Caesar's teachings that "women are beneath notice."

He has likely been in charge of the arena for some time, as he saw the legate fight as a recruit.

Quests

 * Nothin' But a Hound Dog: Since Otho runs the arena, it means he can set up the fight between you and Lupa, one of the dogs whose brain can be transplanted into Rex.
 * Saving (or Savaging) Sergeant Teddy: Like above, Otho can set up a match with 4 Legion mongrels in exchange for Sergeant Teddy, as per Antony's prior agreement.
 * Laurifer Gladiator: Otho will set fights up for the Courier in the arena, but only if they are male.

Appearances
Otho appears only in Fallout: New Vegas.

Bugs
If you speak to him after completing Et Tumor, Brute? he may say "A woman actually proved useful for once. Caesar was bold to put his life in your hands" even if you are playing as a male character.
