Saiyans

Saiyans are a fictional warrior race from the "Dragon Ball" series known for their incredible strength, agility, and ability to increase power through battle experience. They possess a distinctive tail that allows them to transform into a giant ape, called a Great Ape, under the full moon, significantly boosting their power. Saiyans are natural fighters, often seeking challenges to grow stronger, and their most famous member is Goku. Their DNA grants them the potential for rapid and dramatic power increases, especially when they experience intense emotional moments or injuries.
