Banper is a Badnik which was set to appear in the scrapped Zones for Sonic the Hedgehog 2, namely Rock Zone and Dust Hill Zone.
Its design is small with two bumpers on its sides. If these bumpers were touched, they would send Sonic flying in the opposite direction.
- There is a similar Badnik to Bamper called Crawl.
- The name "Banper" is actually a mis-translation of the word "bumper."
- Only concept art of this scrapped Badnik has been found, depicting it has never been used in any prototype versions of the game.
- Banpers are similar in the defenses of the Spiker, as both Badniks can be used as a spring, if the player bounces on top of the defending Badnik.
- If Banper had debuted in Sonic the Hedgehog 2, it would have been the first official Badnik to imprison two Animal Friends at the same time (see concept art below).
