Wechnia is a famous glitch from Knuckles Chaotix. The character appears on the level select screen as "**********". His fan-given name of Wechnia was given as a portmanteau of the words "white" and "echidna".
When selected, Wechnia has Knuckles' sprite, a bizarre white palette and Mighty's moveset. In the Knuckles Chaotix Prototype, Wechnia had the ability to fly, as well as there being a Tails 1-Up icon hidden in the graphic data of the game. Later revisions and the final game rid of the flying ability, replacing it with Mighty's wall jump.
