This is a fight that me and my friend had discussed about, and I felt like making it into a Death Battle. I’m just gonna go ahead and say Discord wins. Main reason being, while the Mask most certainly could fight back, Discord’s capabilities surpass the Mask’s own quite a bit, and while the Mask appears to mostly rely on cartoon physics, Discord has near complete manipulation of his environment and opponents, and so would counter most of the Mask’s attacks and eventually overcome him. Discord may not be able to kill the Mask, but he could still remove his mask once he figures out that part. The Mask would put up an okay fight, but Discord wins this.
