I haven’t tried recreating this yet but something crazy happened with Ken while playing online the other night. comboed into his diagonal dash attack and did the super version right when the hit connected, as per usual. The game did the whole ‘dark background’ super move shit and made the noise for the move, but Ken just did his upwards dash attack instead and both me and the other player were able to move around during the weird background. It lasted the normal amount of time.
