I found a text file on my hard drive with some old ideas for stuff to draw I had written down and one I decided to drag out of mothballs was "something with Sabrina and Sonic," because Sabrina the Witch is an Archie Comics character, Sonic famously had a series done by Archie that Sabrina did a crossover with one time, and both comics had animated adaptations in the 90s done by DiC Entertainment, which in the case of Sabrina is the version I always preferred cuz it's the one I watched as a kid. I went with a cat as her Mobian form because that's a stereotypical witch thing, I would have liked to go with something else because part of the appeal of Sonic to me is that it takes animals nobody's heard of and makes them iconic, admit it, Knuckles is the first time you ever heard the word "Echidna," but I feel like if the DiC version of Sabrina did her own crossover with Sonic and part of the plot was her becoming a Mobian they would have gone for the obvious one too
Also you could argue that this counts as an actual Sonic OC, because if a version of Sabrina is able to cross universes to meet Sonic, then that means she exists in the same multiverse as at least one version of Sonic, which means theoretically there should be a version of her in that Sonic's universe, though I guess the OC-centric groups on DA I submit this to will be the judge of that hardeeharhar
