|A true freak|
|1st appearance:||Escape to the House of Mummies Part II|
Caligula was the infamous freaky, perverted Roman Emperor. He ran into the Venture Family while they were traveling time thanks to the Cult of Osiris. He joined forces with them alongside Sigmund Freud, Edgar Allan Poe, The Perfect Man and a second Brock. When they obtained the Hand of Osiris he was charged with holding it, so he decided to hide it up his ass, repulsing everyone and intriguing Freud. Brock ordered him to keep up the rear with Hank but quickly changed his mind after seeing Caligula's reaction.
