Purple King is the suit, while it is operated by an unnamed Invader, but is an intellectual type that excels at handling parasitic Invaders. Whether the two arrived together or not remains unknown. The Purple King was also an Invader, but was combined with abandoned weaponry of some army on Earth to protect the girl. Due to this, it is essentially a cyborg version of the Mars Gigantalos as it has an extremely similar combat style and recovery tactics.
