Fan Casting Parasite Queen in Metroid 2: Prime

Parasite Queens are the result of a Space Pirate bioengineering program. They possess large muscle structures around their massive jaws, which also contain fluid sacs filled with acid.[1] These fluid sacs enlarge considerably after exposure to Phazon, leading to an increase in production of corrosive bile.[2] Their tail sections end in a large, mouth-like orifice likely used to birth offspring, which survive their mother's acidic embryonic fluid by means of a tough exoskeleton.[3] A Parasite Queen's primary legs possess galvanized tips, allowing it to penetrate a variety of alloys.[4]
