Papa

Papa is the chairman of the APE council and by extension all of known humanity. He is religiously revered by the Parasites as a god, with the exception of Zero Two and Hiro (since episode 7). He works in conjunction with the rest of APE to ensure the plantations run smoothly and that they are not harmed by Klaxosaurs. He also is in charge of all FranXX units; what happens to them is almost always a result of his decisions.

Appearance
Papa wears white robes adorned with golden detailing and a red interior. His mask is the most human of all the APE members, and his outfit bears a resemblance to the traditional attire of the Pope of the Catholic church.

Personality
Papa values the safety of the plantations and APE above all else. He has no qualms about using Parasites as soldiers against the Klaxosaurs, even if it would result in their demise.

History
Not much is known about Papa or his motivations, except that he is one of the scientists who helped develop the FranXX units.

Zero Two
Papa has shown special interest in Zero Two and her abilities as a Parasite. He refers to Zero Two as though he has a personal relationship to her.

Etymology
"Papa" is a word commonly used by children to refer to their fathers, however it is also used in some languages and religious sects to describe the Pope.
