A basic Heavy Mobile Mecha in the early stages of the conflict, only a single Giran Dou was seen. It was contained aboard the Gataman Zan, and flown by first Gije and later Damido in Null Space battles with the Ideon. It may have been specialised for these combat conditions.

The mecha managed to survive both its' early run-ins with the Ideon, arguably being the victor of both. However, when it was later launched as a last-ditch defensive measure to defend the Dorowa Zan (where it was transfered following the abandonment of the Gataman Zan) the mecha was swiftly destroyed by the more experienced colonists.
