Knuckles
3 things,
1. I have no idea why this is even a series, could have easily just been a spinoff movie, especially considering so much could easily have been cut or condensed.
2. It should have been called Wade, or at the very least Wade & Knuckles, considering it was more about him then Knuckles.
3. Six episodes just to end as abruptly as that was crazy, honestly thought we would have got an epilogue were he's back with Sonic and them showing how he's changed since the first episode.
