Since Knuckles's beefed up look in Sonic Boom has become perhaps the most controversial aspect of the whole thing, after the reveal I decided to come up with a tweak using a more traditional build. It's still in a bit of a sketch phase, but a rundown of what I did was slimming his body back a bit, emphasizing his forearms moreso than his biceps, and reducing his height to be a little bit closer to Sonic. All in all perhaps this would be a lot less of a radical shift and there wouldn't be so much backlash from the fans.
I don't mind the official design of Knus in SB,but this DOES look better.
I see this as an improvement. Part of my issue with the new design is that it looks like he'd lose some flexibility. I think a character like him should have an easier time moving, not just be strong.
