Ryouga's Father
Ryouga's father left "The Village of Protecting Time" to go on a journey to chase after bad men. According to Ryouga, his father worked to fight against those who would harm pokemon for personal gain. Before leaving on his journey, Ryouga's father gives his father a gem to pass down to Ryouga when he becomes of age. This gem triggers Ryouga's "Burst" transformation.
