OVA
Description
Gekiryûjin is a Brave robot formed when FuuRyuu (G.B.R.-06) and RaiRyuu (G.B.R.-07) achieve 100% synchronization in their SympaRate, executing Symmetrical Docking. This 28-meter tall, 18-meter wide Docking Vehicle type G-Stone Driven Brave Robot weighs 465 tons. Powered by an Ul-Tech Unified G-Drive with a 9,500,000 kW output, it achieves a maximum running speed of 205 km/h and a maximum flying speed of Mach 0.7. Shoulder-mounted SP Packs aid maneuvering in space, while attaching the supply ship Climber-1 to its back provides extra thrust and power.

Compared to ChouRyuuJin, Gekiryûjin exhibits a more offensive design and combat approach, reflecting RaiRyuu's rougher demeanor and speech pattern. It integrates equipment from both components: RaiRyuu's left forearm-mounted Electric Gun, FuuRyuu's wind-based Jiao-Ban-Ji 4-tube cannon (shaped like a mixing drum), and the Dian-Zhuang-Huo electromagnetic carrier. The Dian-Zhuang-Huo serves as a hoverboard, shield, and ramming/chopping weapon, mounting the Lei-Dun electrical discharger for offensive and defensive manipulation, which also forms Gekiryûjin's chest armor.

Its primary finishing move, Shuang-Tou-Long, generates a yellow and a green energy dragon from its arms. These dragons penetrate defenses like Zonder fields or Primevals to safely retrieve cores undamaged; their energy density even supports allied units like ChouRyuuJin as combat platforms. Gekiryûjin uniquely deploys a desperation attack while docked: FuuRyuu’s self-destruct bomb, concealed in its right arm, used against the Sol Masters in FINAL to overload enemy Loud G-Stones.

Gekiryûjin first fused after FuuRyuu and RaiRyuu reconciled upon witnessing their predecessors' resolve, destroying a combined Zonder Robo and retrieving 42 Zonder Cores. A theoretical combination with G.B.R.-05 ShouRyuu to form ShouGekiRyuuJin exists but remains unused in official media. During the FINAL Sol Masters battle, it employed its self-destruct against Ptulone and used Shuang-Tou-Long to counter electromagnetic tornado attacks.
