If you're wondering what the names of these guys are, I'll tell you: Mecha Sonic (Far Top Left) First Appearance: Sonic The Hedgehog 2 (16-bit) Latest Appearance: Sonic Superstars Metal Sonic (Near Top Left) First Appearance: Sonic The Hedgehog CD Latest Appearance: Sonic Superstars (Sonic X Shadow Generations but that's a port of an older game.) Silver Sonic (Top Right) First Appearance: Sonic The Hedgehog 2 (8-bit, which came before 16-bit), Latest Appearance: Sonic Mania Mecha Sonic Mark II (Bottom Left) First Appearance: Sonic & Knuckles Latest Appearance: LEGO Dimensions Mecha Sonic Mark III (Bottom Right) First Appearance: Sonic Adventure Latest Appearance: Sonic Adventure Credit to SEGA for making these guys. They're all so cool but I think my favorite is Silver Sonic. He is the OG Metal Sonic.
