Nappa was an Elite Saiyan Warrior hailing from Planet Vegeta, who served as the right-hand of the Saiyan Prince, Vegeta. After the destruction of his planet, Nappa served directly under Frieza, alongside Raditz and Vegeta who became a small team. Incredibly simple-minded and lusting for combat, Nappa travelled planet to planet alongside his comrades, wreaking havoc.
After receiving news of Raditz's death on Earth, and hearing of the mystical Dragon Balls that resided there, Nappa and Vegeta decided to head for the planet and claim the Dragon Balls for themselves. After a year of travel, the two arrived and began their search. Very quickly, the protectors of Earth intercepted them, and a battle began.
Nappa easily took on all of the fighters by himself, taking his time to revel in the battle instead of killing everyone immediately. Before he could finally deliver the finishing blows, however, Son Goku made his grand arrival and fought him. After being handily defeated by Goku, Nappa lay unable to walk at Vegeta's feet, begging for help.
Unfortunately for Nappa, Vegeta proclaimed that he had no use for a Saiyan that couldn't move. With one swift attack, Vegeta obliterated Nappa, leaving him nothing but ashes. Nappa was sent to Other World and then Hell by King Yemma, where he remained for the foreseen future.
Alignment:Chaotic Evil (Nappa is extremely cruel, and uncaring to everyone around him. He will maim and torture people for the fun of it, destroy entire cities unnecessarily just in search of the Dragon Balls, and even annihilate entire planets for fun. All of his evil actions are done for his own enjoyment, even disobeying Vegeta's own orders at times)
Stamina: Superhuman (Should be comparable to, if not superior to, early-Dragon Ball Z Goku, who travelled across Snake Way mainly non-stop for over 100 days. As a Saiyan Warrior, who are essentially born for combat, his stamina is incredibly high)
Intelligence:Genius (An extremely powerful and competent fighter, Nappa was able to easily take on martial artists such as Krillin, Piccolo, and Tien Shinhan, all at the same time, who each have several years of fighting experience)
Attack Ball: This round Saiyan space pod only has room for one person, which Nappa used to travel from planet to planet; notably, he used this space pod to travel to Earth. Nappa's Saiyan pod was later destroyed accidentally by Bulma, while attempting to activate it.
Saibamen: Nappa always holds onto seeds that he can plant into fertile soil, which grow Saibamen. These Saibamen are completely subservient to him, and each have a Power Level of 1,200.
Saiyan Armor: Due to being a part of the Saiyan Army and Frieza Force, Nappa has Saiyan Armor. This armor is unbelievably durable, but also incredibly stretchy; the armor can stretch so much that it fits around Saiyans when they turn into a Great Ape.
Scouter: Technology developed by the Tuffle race, but adopted by the Saiyans after the Tuffles were wiped out. This advanced piece of technology can detect the presence of life forms, calculate anyone’s battle power, and can also be used for telecommunication.
Notable Techniques
Flight: With a mastery of Ki control, Gohan is able to fly at incredibly high speeds.
Ki Blast: Using Ki, Gohan can concentrate it into a ball that he uses as a projectile attack.
Volcano Explosion: Nappa rises his right hand with his index and middle fingers up, releasing a white Exploding Wave.
Arm Break: Nappa charges up a ton of Ki into his hand, and delivers a powerful punch to the opponent's arm. This has been used to sever Tien Shinhan's arm.
Break Cannon: Nappa fires a huge beam of Ki from his mouth.
Eye Lasers: Nappa can fire Ki beams from his eyes.
Bomber DX: This move has Nappa build a ton of Ki in his palm, before throwing it like a bomb that explodes on contact.
Other
Standard Tactics: Nappa will envelope a tactic of using weaker attacks against his opponent to make them suffer, though if they are stronger then him or around his level he will use his more powerful attacks and attempt to finish them off with ki blast/ki attacks.
Weaknesses: Due to the nature of ki draining stamina and energy, Dragon Ball characters ki usage requires them to usually use their higher levels of energy in short bursts, allowing them to not be able to tank or die to far lower attacks such as attacks that havedestroyed severalplanets in the series. Synonymous with the Saiyan warriors, Nappa is extremely overconfident and arrogant when he faces fighters he perceives to be far weaker than he. He cannot sense Ki, and relies on his scouter to tell him the strength of an opponent. When he is cornered, Nappa grows desperate and loses his edge.
