Gatekeeper was picked by the Godfather to assist in the Godfather's dream of creating the perfect idol world. Even after the Godfather's death he swore to continue pursuing this dream. Gatekeeper is cold, calculating, does not have any motivation or feelings, and has no interest in getting involved with other people. He is murderous, calmly violent and dangerous. At the same time, he's warming up to his nephew and feeling feelings of parenthood for the first time.
