well why the fuck not

A character in a light-colored outfit stands before a large golden door, then the scene cuts to a close-up of his face showing intense strain and a toothy grin. The view shifts to a red-tinted, monstrous form with sharp teeth and glowing eyes, its mouth open in a roar. The sequence loops, showing the character's transformation into the red, beast-like entity. The setting is a dark, enclosed space with a glowing circular pattern on the floor.
