“The essence of champions flows through your veins. When you cannibalize corpses you temporarily gain Caesar's intelligence, Mr. House's luck, The King's charisma, and President Kimball's strength.”— Fallout: New Vegas description
Having the Cannibal perk and eating the corpses of Caesar, Mr. House, The King and President Kimball.
The easiest way to obtain this perk is to side with the Caesar's Legion because President Kimball and Mr. House can be killed through quests. Additionally, when doing the quest Et Tumor, Brute?, there is an opportunity to kill Caesar and keep the guards friendly through a Speech or Medicine check.
Does not affect human remains.
