So it's more like "This Infernape has a unique and unexpected power over Ice" rather than "lol mystery attack, who could possible know what I'm doing? I don't know what I'm doing. Actually, am I doing anything? Who said I'm doing anything? I didn't do anything. You believe me, right? You didn't see shit, nigga."
