Description
Nivil competes in the Tavanel Cup tournament during the events of *BakuTech! Bakugan Gachi*. His primary Bakugan partners are Go Garyu and Gaga Horus, and official product descriptions designate him a "super main character" (超メインキャラ, *chō mein kyara*).

Within the anime, Nivil emerges as a notable opponent in the Tavanel Cup. He faces Raichi in the tournament semifinals, a matchup highlighted in the episode "Semifinals! Raichi versus Nivil!" airing on May 11, 2013. This battle occurs during the anime's second season.

The anime adaptation presents battles and narrative elements absent from the original manga. Nivil's confrontation with Raichi unfolds with greater length and detail in the anime. Furthermore, the anime expands his battles to include conflicts against characters Sho and Koh, encounters not found in the manga storyline.
