It's Adam Arrunda from my old Sonic-comic-based fan-fiction. Adam was always a popular character with my friends of that era when I was writing..........and he was one of the most "evolved over time" characters as well. He's always fun to draw just randomly every so often.

OC is mine, character was set in the Archie Comics-based world of Mobius. Echidnas of this anthro design and style, of course, belong to Sega. :)
