Description
Lumagrowl is a wolf or fox-like Bakugan with six tails, each equipped with swords that allow for attacks at close and intermediate range. Primarily partnered with Kazarina of the Twelve Orders, he represents the Haos attribute within this Gundalian group.

His personality is marked by arrogance and a constant desire for power and combat. He rarely shows emotion beyond this pride, making his intentions difficult to read. Yet he demonstrates a sense of honor and unwavering loyalty to Kazarina, a trait that becomes more pronounced after her death, when he accepts defeat and shows respect for his fallen partner.

Lumagrowl first appears in a video transmission fighting Neathian forces alongside Bakugan like Dharak and Krakix. He is later seen in an illusion experienced by Dan Kuso, battling the Castle Knights with the Twelve Orders. His physical debut involves helping destroy Neathia’s first shield and defeating Raptorix and other Castle knights alongside Krakix and Strikeflier.

A significant rivalry exists between Lumagrowl and Aranaut. They clash during the attack on Neathia’s second shield, though the battle is interrupted when the Sacred Orb warps all Gundalian forces away. In another engagement, Lumagrowl and Phosphos battle Lumino Dragonoid. Lumagrowl wins the first round, but after Dan and Hawktor arrive, he is defeated by Drago.

His loyalty is evident when he defends Kazarina from an ambush by Lena Isis and Phosphos, intercepting the attack and defeating Phosphos. He also helps punish perceived treachery, such as when he and Lythirus attack Plitheon for wanting to abandon his partner, Jesse Glenn, with Lumagrowl condemning the act as despicable.

In battle, Lumagrowl uses ability cards including Arcadia Sword, which transfers 500 Gs from an opponent; Flashing Peaker, which absorbs an opponent's ability upon contact; and Blade Fantasma, which subtracts 400 Gs and prevents further ability activation. Other abilities include Wolf Howler, Garm Shield, Skoll Fang, Burn Fantasma, and the powerful Time Warp, which resets the brawl to a previous point, nullifying all subsequent effects.

He is equipped with Barias Gear, his designated Battle Gear, which grants time-warping abilities used in combat, such as when he defeated Coredem. Lumagrowl is one of the few Bakugan in the anime depicted with physical pegs for attaching Battle Gear.

His final confrontation with Aranaut occurs after Kazarina's death. Distracted by the revelation, Lumagrowl is struck down by a powerful blow. After his defeat, he surrenders honorably, retrieves Kazarina's body, and walks away to bury her, mourning her loss.

Lumagrowl is revealed to have been responsible for the death of Jin, a Castle Knight, and the capture of Aranaut in a past event. After the conflicts conclude, he is one of the few surviving members of the original Twelve Orders who did not defect to Neathia.

In the physical game, the Lumagrowl toy was produced in multiple variations across attributes including Pyrus, Aquos, Subterra, Haos, Darkus, Ventus, and a Clear version, each with varying G-Powers.
