As expected, Sonic's incredible movement speed and Spring made it very easy to dodge. You can run and Spring out of trouble with ease. Despite Sonic's rather low damage output, no boss took more than a few tries; if you can't get hit you can't lose.
Also for some bonus trivia, Sonic is the only character fast enough to safely physically attack the Duon at the start of the battle on intense. Try with anyone else, and you're guaranteed to get hit by the Duon's almost immediate attack. Plus Sonic's Spring trivialised the Duon's charge attacks, which for most characters is one of his most dreaded attacks, with its wonky hitboxes that drag you making it extremely difficult to completely dodge sometimes.
