This Beast Warrior was initially a creation combining alien genetics with aspiring human boxer Ryuu Wakasa, in hope of creating a Beast Warrior that would be stronger than the Flashman. However due to using Ryuu himself instead of merely taking his genes, there was great instability in his creation, particularly due to his friendship with fellow fighter Dai. The creature switched back and forth between human and Beast Warrior forms, further made unstable when Dai tries to reawaken Ryuu within the being by playing his trumpet. Ultimately against Lie Köpflen's protest, Lah Deus forces the Beast Warrior to be separated from Ryuu, keeping the genetics but dramatically weakening it. The separated The Jagan is easily destroyed by the Rolling Vulcan, then by Flash King.
