The character Windrazor was an exclusive toy for the BotCon 1999 convention.
Some characters were included in one version of the game and left out of the other. Terrorasur, Waspinator, Starscream And Airazor were playable characters in the N64 version but not the Playstation (although Waspinator did has a brief appearance). Similarly Rampage, Windrazor and Quickstrike were playable in the Playstation version but not the N64 version.
Both the Playstation and N64 versions of the game had Transmetal versions of Airazor, Waspinator, Terrorsaur and Rhinox. While toys were made of them, their Transmetal forms never appeared in the show.
