Roy pulled something from his pocket—a small red pill—and swallowed it with a desperate gulp.
The change was instant and horrifying. Roy's body convulsed, muscles bulging beneath his skin as he grew larger. His entire form expanded, skin flushing crimson as veins popped across his expanding frame.
'What the hell did he eat?' Arthur thought, intrigued but not concerned.
"You made me do this!" Roy roared, voice now deep and distorted. He grabbed the tree trunk piercing his chest and yanked it out with a wet, tearing sound. The gaping hole remained, but he seemed unfazed.
"I'll make you join me in hell!"
Roy charged, moving faster than his new bulk suggested possible. The ground cracked beneath each thunderous step.
Arthur sidestepped casually, creating a spatial distortion that sent Roy careening into another tree.
"Interesting," Arthur mused. "A transformation pill? It has demonic essence, too?"
