Meanwhile, Sitch gathers captured villains at the Hero Association headquarters, assuring them there is no deception. Flanked by powerful A-Class heroes as guards, he prepares to explain the situation. However, the scene is abruptly interrupted by Speed-o’-Sound Sonic, who refuses to cooperate with Sitch’s plans and makes his defiance clear.
