In addition, he has horns, fangs, and red skin due to his demonic morphology, and has superior senses comparable to those of a demon.
His powers can be quite terrifying and powerful, especially his ultimate moves such as WALL OF FIRE, which can incinerate anything that comes into contact with it.

He is someone who is not to be underestimated, but he must also be aware of his limits and take care not to let his powers get the best of him.
