Shamoians are small creatures with most commonly a green skin color, the elderly generally having a darker skin. The young members of the race sports mohawks, and the most common hair color seems to be purple.
Sometime between the destruction of Planet Vegeta and the events of the movie, Paragus enslaved the Shamoians to do his bidding after a young Broly left their home world of Shamo in ruins. The Shamoians that were on New Planet Vegeta were led by an elderly member, with his young grandson serving as his attendant. While undergoing slave labor, they often looked up at the sky at Shamo with the hopes of going back to it someday, something that Broly observed at some point. At one point, as part of the events of the movie, Shamoians enslaved on New Planet Vegeta encounter Gohan, Future Trunks, and Krillin; the trio save them from the punishment of Paragus's minions, and then question the slaves about whether Paragus was responsible for the destruction of the planet while feeding them, which they deny, citing that it was actually a much bigger and stronger Saiyan who did the deed. As they had been starved during their enslavement, the slaves ravenously eat the meal, causing Gohan to tell them to slow down before they "pop." The next day, the Shamoians are brought before Vegeta via Gohan, Krillin, Master Roshi, and Oolong, at Future Trunks' behest to expose the slave labor going on at New Planet Vegeta as well as it being ruined, with one of the Shamoians recognizing Broly as being the Saiyan who attacked Shamo. One of the first things Broly does upon reaching Legendary Super Saiyan in the movie is killing hundreds of them with a single blast while laughing with sadistic glee. Krillin, Master Roshi, and Oolong managed to rescue the survivors including the elderly one and his grandson, but not before Broly taunted them with freedom and destroyed planet Shamo. It is assumed that they eventually found a new place to live after the destruction of New Planet Vegeta.
