You made some mistakes on the readme. Blast zone is QCF+P, you listed it as QCB+P. Also, fighting spirit uses 2 powerbars, not 1.

Apart from those mentioned by Cyan Paul... the DB+K launcher in the corner can be repeated as an infinate.  The damage scales to nothing after 12 or so of them but still...

Can't seem to combo into anything after a chain combo, but then I can't seem to combo any of his supers except after the launcher.

Might just be me... but feels like he needs a chain throw or an air throw.  **shrugs**  Will keep playing around with him.  All in all though, not bad at all!

- He's supposed to be fast and light, but his jump feels really too light IMO.
- When Ruckus jumps over an opponent, if you continue jumping in the same direction, he'll be facing the wrong side.
- On his HP+HK throw, a noise when he kicks/jumps from the opponent would give more "power" to the move. It seems weak as it is.
- All in all, during his specials, I think some of them (if not most) would gain in having some envshake, because the moves seem a little weak without them.
- A problem hard to perform : place the opponent in the corner, and make him walk forward just a little (the size of one foot). Then perform Fighting Spirit! Just before the last attack, Ruckus will push the opponent against the wall, and cornerpush will not be taken correctly into account, resulting in the last attack missing, as shown in this image :

- Super Blast Zone's FX has shadow, which doesn't look really nice.
- Super Blast Zone can miss cornered opponents.
- Kicky Fast's last hit doesn't connect on all opponents. For example, it didn't connect on SPO Ryu by Rikard.

You can be proud of Ruckus, he's a really nice character.
After seeing some of his anims, I was hoping he wouldn't be too close to Ramon, gameplay-wise. You didn't disapoint me. While some animations and one or two moves are clearly taken from Ramon's arsenal, all the changes and things you've put in this character make him play completely differently. As said, an air throw would be a nice addition to his techniques.
I'm more and more fan of moves with follow-ups, and To The Five Boroughs (2T5B) is the perfect example of what I like. Great job on this move.
Throws bind perfectly and very smoothly from what I saw, which isn't always easy to achieve.
Finally, the additionnal shades you've added to him really make the sprites look even better, even though the style hasn't changed in itself.

I'll be waiting for the AI, and especially for Byrne now. Good luck.
