Oh Sonic... here we go again...

something that djanjo reminded me of (although not very related to what he was talking about) was how in Knuckles Chaotix some characters kind of had a different way of spinning.

Knuckles and Mighty did the normal spinning jump/dash that Sonic has.
Espio kind of did a pirouette
While Vector, with his (previously) slim body, spinned like a wheel

Sonic's spinning like a ball is his signature move. Other than him, I think only Mighty should be able to curl in a ball like Sonic does. All other characters should have a form of spinning, but different than Sonic's and fitting to their abilities. (Tails can spin his tails like he usually does for flying, and Knuckles can spin his arms around to dig and break walls maybe?)
