Nappa is one of the most talented Saiyan warriors of planet Vegeta. After Vegeta was wiped out, he followed Vegeta and spent some time with Vegeta working under Frieza. Later, he and Vegeta came to Earth to rule the Earth but he failed, defeated by Goku and killed by Vegeta.
Nappa is a tall, muscular man, though nearly 50 years old, but he is still 30. He is a very conservative, destructive and destructive. Typically, upon arriving at Earth, while waiting for the Goku, he uses his power to attack, destroying many things in the city.
He is also a very cocky, cruel, cruel, joking about the pain of others and also enjoys joking with his opponent. However, in combat, he is often “cheating”, often using the muscle instead of using the brain. At the same time he has a short temper and no patience, there are often lost his temper made him in battle. However, for Vegeta, he always has a certain respect and most of him are obedient and follow Vegeta’s instructions.
Nappa possesses tremendous power, much stronger than other senior Saiyan warriors. During the fight with the Z Warriors, he showed his power when he completely defeated Piccolo, Gohan, Krillin, Tien Shinhan and Chiaotzu. Only when Goku appears and Kaio ken is defeated.
Unlike Goku who was born into a lower class Saiyan, Nappa came from the upper Saiyan class. So he always has a high position in his race and his energy level is much higher than other Saiyans. So he was quickly credited by King Vegeta and joined forces in the invasion of planet Tuffle.
