Shun Kazami

Shun Kazami lives in the province, and is a Ventus attribute player. He is a loner, yet he is willing to help his friends at all costs. Together with Dan Kuso, his best friend and childhood friend, he invented the gameplay for Bakugan. He had been the first ranked battler until Masquerade and his minions dominated the rankings, and Shun moved to sixth place. Shun was once considered a fierce rival of Dan Kuso by Dan himself however Shun never acknowledged this and it seemed that dan had a deep jealousy for Shun's skill in Bakugan.

Shun once leaves the brawlers when Dan says they don't need him. But after brawling Komba, Dan appears and asks for forgiveness which Shun accepts.

New Vestroia

Shun appears in Bakugan: New Vestroia with a new Bakugan, Ingram. As of now, it is shown that Dan and the others have failed to get in touch with him. However, in episode 4, he makes a cameo debut after Marucho passes out from his battle against Mylene. We hear Mylene tell him that she doesn't want to keep losing to him, and asks him if he wants to join the Vexos. When he doesn't reply, she takes that as a no. Shun then leaves, leaving Mira to wonder if he was her brother.
