This is Sammy The Speedster! Look at him, LOOK AT HIIIIIIIM- Press Space for the next version. :]
Real quick the concept for Sammy is that he is a knockoff sonic that mysteriously appeared in stores, most copies were discovered and removed by the staff because people thought it was clearly a knock off, sense the company that made it can't be traced the games are just, floating around, but clearly, the games are HaUnTeD!!!! OoOoOoO... anyway, so Sammy has two forms, his normal form, where He's just relaxing and living his life, and his second form, which is, E... So, the concept is that for most of the game it's just normal, with a few glitches and what not, but once you make it to the final world you start playing as Mr. Mecha, the rip-off of Eggman and Antagonist, and you are just trying to kill Sammy, as he tries to murder everybody else after going all wacky, so yeah, Sammy, he's a thing now, and he's my thing. :]
