Coller2 (コーラー2 Kōrā2?) (preliminary name) is a canceled character that was planned to appear in Castlevania for the Nintendo 64.
She was going to be somehow related to Coller and was originally intended to be his rival. She was supposed to be a creature for which a newer technology than Coller's was used.
During production, the character was eventually abandoned completely and never made it into the game, with only a single concept artwork of her remaining.
