while i don't know what move you're talking about,
insanely strong attack that can follow up on a stun
Any move can follow up on a stun. Or do you mean if you get hit by his projectile when it's charged enough to stun you longer?
or punish their opponent for trying to close in on them
unsafe approaches get punished
seriously though what move of his does 30%? are you somehow getting hit by his full charge neutral B so close that you get bitten too??
