This started out as a simple attempt to nail down how I wanted the character model of Robotnik to look when I drew him, but I thought it came out well enough to bother inking it and slapping on some color. While checking screenshots for reference, one of the oddest things I realized about SatAM Sonic that I never really paid attention to before was that neither Robotnik nor Snively have eyebrows in the cartoon. It's kind of creepy looking.
