The Water Tribe is one of the four elemental tribes featured in Toho's 2003 show, Chouseishin Gransazer. This tribe consists of Sazers Gorbion, Pisces, and Gans, all of which have water-related abilities and weapons. Together, they can summon their tribe's Chouseishin, Leviathan.
The Water Tribe (水のトライブ,Mizu no Toraibu?) appeared after the Akelon incident and was the fourth to awaken fully. Led by the strict and mistrusting war photographer Makoto, this tribe fought a while on their own. After having been completed as a tribe and awakened their Chouseishin, Leviathan, they joined the other Sazers. The suits of the Water Tribe are based on sea animals and have shades of blue, piloting the Aqua-Driver Grand Vehicles.
