The Visitor [Godzilla: Unleashed]
"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." – Proposed bio
And here’s the Visitor an unused kaiju from the 2007 game Godzilla: Unleashed. as you can see it is an Alien Kaiju and also a Bio Organic Weapon that looks like a Xenomorph from the alien movies although much larger in size.
