Sharps the Chicken is a Mobian chicken and the bassist for the Forget Me Knots. He's generally very laid back and doesn't speak much. He rarely takes off his dark shades. (StH: #200, StH: #220)
Sharps is from the scrapped "Sonic the Hedgehog Band", which appeared in concept art prior to the 1991 release of the first ever Sonic the Hedgehog game; the band was supposed to play music when a player accessed the "Sound Test" option of the game.
Despite SEGA owning the rights to Sharps, and therefore allowing the character to be used again in the Post-Super Genesis Wave Timeline, he has not yet made an appearance in the current comic continuity, and whether or not he will is currently unknown.
