Otho

 runs the Legion Arena at The Fort in 2281.

Background
Not much is known about Otho, other than him being sexist, as Caesar says, women are beneath notice. He saw The Legate fight when he was only a recruit, indicating he has been in charge of the arena for some time.

Quests

 * Nothin' But a Hound Dog: Since Otho runs the arena, it means he can set up the fight between you and Lupa on 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 mongrols in exchange for Sergeant Teddy, as per Antony's prior agreement.

Appearances
appears in Fallout: New Vegas.

Bugs
Otho may speak to you as if you were a woman, even if you're not.
