*TRONCO XR28 – A green, chainsaw-wielding, limbless robot, with a resemblance to the pre-Henchman 800 mentioned above. This appears to have been a powerful enemy, and may have even been a boss.

*[[The General]] – This character was initially set to appear in the 2D ''Rayman 2'', but made only a cameo appearance in [[Rayman 2: The Great Escape|the final 3D version]], in which he sold the [[Grolgoth]] robot to [[Admiral Razorbeard]]. [[The General]] also appeared in the intro sequence of the PC/N64 version of ''[[Tonic Trouble]]''. His willingness to allow [[Razorbeard]] access to the powerful [[Grolgoth]] so that he can destroy [[Rayman]], as well as his appearance in a promotional video for the 2D ''Rayman 2'', implies that [[the General]] may have originally been intended as an evil character for the game, possibly even the main villain. One piece of artwork shows him standing on a wrecking ball, apparently shouting orders to Robo-Pirates while Rayman stealthily approaches.

*Monocle-wearer – This pale, grinning, evil-looking robot is shown in one image wearing a monocle on one eye and clutching a [[cage]] between two fingers. His role in the game is unknown.
==Playable PlayStation level==
In the final 3D Sony PlayStation version of ''[[Rayman 2: The Great Escape|Rayman 2]]'', the player can unlock a single level from the canceled 2D version of ''Rayman 2''. This is done by collecting at least 90% of the [[Yellow Lums]], then completing [[the Crow's Nest]] level. Since the PlayStation version of ''[[Rayman 2: The Great Escape|Rayman 2]]'' has only 800 Yellow Lums to collect, the player only needs to collect 720 of them in order to access the level. The level takes place in a grassy environment with strange rock formations in the background, in addition to a cloudy, purple sky. Music from [[the Walk of Life]] level plays in the background.
Its exact meaning is unknown; however, Vincent Greco was the lead programmer on [[Rayman 1|the original ''Rayman'' game]], and went on to work on ''[[Rayman M]]'' and ''[[Rayman 3: Hoodlum Havoc]]''. Judging by the appearance of his name in its files, it would seem that he was also involved in the production of this prototype.
