Kotaro Ogami, alias Tigerwolf, stands as a key member of the Toraburyu force in *Gunpla Battle Nexus Online (GBN)*, renowned for his aggressive close-quarters combat style rooted in martial discipline. His rigorous training and technical precision earn him respect among fellow Divers, though his self-styled "manly" demeanor often falters during encounters with female avatars.

Tigerwolf pilots the custom XXXG-01S2龍虎 Gundam Jiyan Altron, a modified Altron Gundam (*Mobile Suit Gundam Wing*) adorned with tiger and wolf motifs. The unit features detachable shoulder armor, leg-mounted Jiyan breaker blades, forearm-mounted Jiyan fang flamethrowers, and a throwable shield. Its signature techniques—Ryukorodo’s rapid melee strikes and the Raijin Thunder’s electrified assault—blend martial artistry with advanced weaponry.

Initially a rival to protagonist Riku Mikami, Tigerwolf evolves into a mentor, reluctantly acknowledging Riku’s resolve. He shields Riku’s team from hostile Divers, later testing their growth in a formal duel. Though victorious, the battle cements mutual respect.

Two years post-*Gundam Build Divers*, Tigerwolf joins the Lotus Challenge rehearsal, a tactical drill against antagonist Alus’s forces. His participation alongside veterans underscores his enduring role as a strategic pillar within GBN’s community.
