* HeyItsThatVoice: Py-Ro is TheJoker, and Wa-Wa is [[FullMetalJacket Gunnery Sergeant Hartman]].
* WhatCouldHaveBeen: ''The Wrath of Cortex'' was meant to be far more revolutionary under Mark Cerny's direction, taking on free roaming elements akin to those ''Twinsanity'' would later take on. Ultimately however, developers shyed away from altering too much of the franchise and remade much of the game into a borderline copy of ''Warped''. Remaints of unused areas and concepts actually still exist in the final game's memory (and in cases such as "Crash and Burn" and "Ice Station Bandicoot" were disguised inside the final more conventional level designs).
** The game was also set to be released on the Dreamcast before its production ceased.
