Saiyans

Saiyans are agressive race of warriors. They were almost extincted by Frieza. They love to fight, as it's seen during Dragon Ball series. They now live on Earth and help out defeating villains, which some can be Saiyans. It's said Gogeta's the strongest Saiyan to exist in Dragon Ball World.

Usual appearance
Saiyans are very similar to Humans in their appearance, but there are some differences. They are usually muscular, since they're powerful race. Their hair never grows, as it's stated by Vegeta, but Saiyan hybrids' hair grows, since they're not full-blooded Saiyans. They have tails when they are borned. They help them to transform into Great Apes, a mighty transformation that's used to destroy Tuffles, another race that lived on planet Vegeta.

When they started to work for Planet Trade Organisation, they got Saiyan armors. These are flexible armors of unknown fabric. There are few versions of these armors. THese include scouters, that are used to detect someone, read power levels and communicate.

On Earth they wear casual clothes of Earthlings.
