The inhabitants of Planet Shamo appear to be quite a peaceful race, with very low strength. Appearance wise they are all extremely short, with green scaly skin and mohican style hair.
Their planet was invaded by the Legendary Super Saiyan, Broly, who destroyed everything on their home world and left it in ruins. Paragus then took all of their people and forced them to work as slaves on New Planet Vegeta. The Shamo people dreamt of someday being able to return to their home world, but it was later destroyed completely by Broly.
When Broly was eventually defeated, the Z Fighters managed to save a large group of Shamoes, and it is assumed that they were left to restart their lives on a brand new planet to call their home.
