Nappa was an Elite Saiyan Warrior hailing from Planet Vegeta, who served as the right-hand of the Saiyan Prince, Vegeta. He also serves as one of the primary antagonists in the Saiyan Saga of Dragon Ball. 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 Intelligence (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)
Accelerated Development (Training; Physical Stats, Skill, & Abilities; Nappa as well as others can train and quickly grow stronger, surpassing even the earthlings)
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 envelop a tactic of using weaker attacks against his opponent to make them suffer, though if they are stronger than him or around his level he will use his more powerful attacks and attempt to finish them off with ki blast/ki attacks.
The speed scaling for PLs are taken with a grain of salt as there are noticeable times where someone's speed isn't equal to their power, such as Burter being faster then Recoome and Jeice, along with Super Saiyan Grade 3 Trunks having his power greatly increased but his speed decreased.
In the fight of Trunks vs. Mecha Frieza, who is far stronger than his final form, Mecha Frieza immediately goes for his strongest attack, the Supernova. In the original Z anime King Kai even states this is ten times stronger than the power he used on Namek:
Original DBZ Anime Version[252]. The attack is directly noted that it could destroy the planet, but doesn't because Trunks catches it, when Mecha Frieza proceeds to detonate it, the explosion is massive but the planet is still intact, implying Frieza must target the core in order to destroy the planet.
