Father

Father is a major antagonist in Sunverse. He is a nearly-immortal Pokemon/human hybrid created from the DNA of a passerby Mew and the man who would eventually become Van Hohenheim, and pulls many of the strings that lead towards near catastrophe in Kalos 3,000 years later.

Basic Information
Father is a creepy orb in actual FMA, so what better to do than turn him into a Pokemon, too?

Appearance
Father, at first glace, looks like an elderly Van Hohenheim. Further inspection, however, will paint an entirely different picture.

Personality
Father is incredibly composed (and quite frankly, a little dry) when first encountered.

Creation and Bonding
Father, originally only called "Monstraculus," was created 3,000 years ago.

In Moonverse
Father does not exist in Moonverse. Technically, his counterpart would be Dante, but she isn't even really much of an antagonist in the verse, as much a bother. And an asshole.

Van Hohenheim
Bitch.

Trivia

 * Father's access to most Pokemon moves and all types is both a reference to Mew, the Pokemon he was created from, and Arceus, the being most similar to Truth in SUMOverse.
 * Father could be considered something of a predecessor to Mewtwo in Sunverse. However, Mewtwo is a failed clone of Mew, rather than a hybrid. Father being related to Mew is a nod to Mewtwo's featuring throughout Kalos (and in Sunverse, Father effectively takes the place of any lore related to Mewtwo.)
