The Street Fighter cartoon was pretty miserable. At least we got Tiny Dee Jay out of it.
There was also a Darkstalkers one that I wanna say only lasted maybe two or three episodes? Capcom maybe wasn't making the smartest decisions over in the US.
For the longest time I thought that maybe I'd just come up with that Darkstalkers cartoon in a dream, since I only managed to catch it on TV one time at like 4:00 AM. But it definitely existed. Apparently there were 13 episodes.
On a side note, the 13th and final episode is titled "Everyone's a Critic", which I'd like to imagine is some sort of commentary about the show's quality and reception (but probably isn't).
*edit: One last note, here's Demitri and Morrigan looking like total dorks on the VHS box.
