Since their Gitaroo is ingrained into their bodies, they are a unique warrior unit that combine their efforts in each attack. They all share the same name (Sanbone), but it's not clear if they are related to one another. Even so, they collaborate with one another pretty well, and they are jokingly referred to as the democratic soldiers in the Gravillian Empire. They have voice credits in the Japanese version. Pine is voiced by Daisuke Tōjō, Hirofune Tanaka voices Carrot, and Yasuhiko Tokuyama does the voice for Soda.
