Boy > Vexacion
What happens when a litter of part-divine fire-breathing robot puppies grows up? Simple: They become an army of part-divine fire-breathing robot dogs, all of whom follow Boy around faithfully and do whatever he commands. Like, say, for example, descending on the arena and ripping Vexacion to shreds before the Regent could even draw his blade. The judges, fearing the same fate if they incurred the wrath of the vicious canine army's owner, awarded Boy the victory. This newfound power did not go unnoticed by the formerly good-hearted hero.
Boy's domination of the RPG multiverse has only just begun.
