It isn't, as of last week. However, they are growing increasingly secluded, and I have no clue what they messaged me on twitter because they deleted...
King Aquamentus was born in the quaint land of Ponyville to proud parents Spike and Rarity, thus explaining a lot of his biology. Despite this, King Aquamentus greatly protests being a pony *or* a brony, on the grounds of "I'm a fucking Unicorn/Dragon thing."
He recently moved to "narrow path to the door" land and has been happy ever since.
