Modeler/Animator Chris Chin explained, "The Visitor was inspired from the two existing alien monsters, Gigan and Orga, possessing a similar outer world look. The Visitor is native to an extremely harsh, mountainous planet and has four hooked claw appendages protruding from the creature’s spinal column.
Reminiscent of the older Gigan's hook arms, these limbs are used as weapons as well as tools for digging and climbing. The overly-exaggerated maw filled with dagger-like teeth was taken from Orga's later form when he tried to consume Godzilla. This fearsome mouth is convenient considering the Visitor’s diet of gargantuan space worms which live in the planet's crust. These worms consume various sorts of unknown alien minerals which provide the Visitor with a nearly indestructible skeletal structure."
|“||In their bid to retake earth, the Vortaak aliens have conscripted a new secret weapon into their arsenal of monsters. The Visitor is a feral alien creature captured from its home planet by the Vortaak with the intent of turning it loose on mankind. The monster clamps down on opponents with its massive jaws and stabs them with its crab-like appendages. The Visitor can also employ a Brainspasm, which shoots a directional shockwave from its pulsating cranium."||„|
