The RX-78-lā-III Lah Gundam (RX-78-lā-III ラーガンダム Rā Gandamu?), also referred to as the Sangata (参型?), is a Gunpla appearing in Gundam Build Metaverse.

A Gunpla Rio Hojo built using the RX-78-2 Entry Grade model as a base. Primarily movable areas such as the unit's shoulders, waist and knees have been customized, and while the scope of its alterations may be rather straightforward, they work to great effect. Using as many of the unit's basic elements as possible, this custom Gunpla aims to get the most out of the smallest amount of customizations, and the ease at which the Entry Grade kit can be assembled makes it the perfect choice for a beginner like Rio. The Lah Gundam, its name inspired from the Hawaiian word "Lā" meaning sun, spans specifications from the two iterations of the original Gundam: it has been reverted from the white and blue color scheme of the unit's prototype iteration, the Shisaku Ichigata; it features the reinforced joints of the Nigata; and houses other reinforcements and new weaponry seen on the Sangata. Much like its namesake, the Lah Gundam, thanks to the experimentation and careful construction its creator, rises like the sun, shining brightly on his Gunpla battle journey.
