Kyoya is one of the Main Characters in Metal Fight Beyblade Anime. He was also the Leader of Face Hunters, and is always trying to defeat Gingka.
In Beyblade Metal Fusion and Metal Masters, Kyoya has a green spiky hair, blue eyes, and a green jacket that seems have the sleeves ripped off. He also wear a black shirt underneath, which has been ripped just above the waist. He also wears long brown pants ragged a little at the bottom, with brown boots, plus a necklace. He also have two cross-shaped scars below his eyes, though why and how, we don't know.
In Beyblade Metal Fury, he still has the hair, eyes etc, but his clothing is different. He wears a short grey vest, a different necklace, light grey pants and brown boots.
Kyoya is seems cocky and arrogant in the first episodes he appeared in, challenging the main character and hero Gingka. Later, he becomes more quiet, and speaks less, although he does speak out more when he is battling, or talking to Gingka.
In Beyblade Metal Fusion and Metal Masters, he had a Rock Leone. In Metal Fury, he has Fang Leone. Both use a lot of wind and all the special moves.
