Yaza

Yaza is the commander of the group that terrorizes Madoro City. By combining his modified ararebo with the energy from a group of fire-type pokemon, he creates a flaming weapon able to cause a great deal of damage. He is not above using dirty tricks to get what he wants; at one point in the story, he kidnaps a little girl and threatens to burn her to a crisp if Ryouga doesn't fight him.
