The character Nina Cortex was created by Traveller's Tales Oxford Studios for Crash Nitro Kart. However, Vicarious Visions was assigned to develop the game instead, so TT-Oxford planned to debut Nina in Twinsanity. However, when screenshots of Crash Fusion (developed by Vicarious Visions) revealed that Nina would appear in that game, TT-Oxford was shocked, as they had not been asked or even notified that their work would be used in another game, which would release even before their own.
