Sonic's Counter Picks

Spam the move where he spins like a bitch and run away for the entire match

Don't play this fighter, it's not fun playing as and against him! Just kidding, try using up-B as an edgeguarding tool, it's good against fighters with a bad recovery like Docter Mario.

One thing I always do when I play sonic is choose a better character

When an enemy is recovering from far enough that air dodging isn't viable, it's typically a free kill if you run off stage and neutral B, release when they are close, just don't let them past you

roll nigga, that all you gotta do
