Once Vegeta's partner, Nappa traveled to Earth with the Saiyan prince in the hopes of gaining immortality along with Vegeta. After killing Yamcha and Tien, he would be confronted by Goku, who defeated him with little effort. After being rendered paralyzed by one of Goku's attacks, Vegeta would kill him in cold blood for the crime of being of no more use to him.
In Dragon Ball FighterZ, Nappa is a slow but strong bruiser who supplements his attacks with Saibaman footsoldiers that he can grow during battle. It takes time for the Saibamen to grow and be of use, but once they are in the field, they can disrupt opponents and leave them open to Nappa's punishing blows.
