Not much about his past is shown, except that he is the strongest namekian on planet Namek during the start of the series.
Nail takes on a very heroic, honorable persona. He dedicates his life to the protection of Grand Elder Guru, the Grand Elder of Namek. He cares deeply about his Namekian brothers, something he shows greatly during his battle with Frieza as he jumps into the battle with little concern for his own well-being. Despite being the most powerful Namekian of his time, with a power level of 42,000 (making him comparable to the ranks of the Ginyu Force in power), he is easily brushed aside by the immense power of the galactic tyrant Frieza. Despite being completely outmatched, he continues to attack Frieza, only to suffer a brutal defeat. After fusing with Piccolo, his soul continues to reside within the ultimate Namekian warrior, giving Piccolo his knowledge.
Nail takes a very similar appearance to Piccolo. He dons a blue vest and a white scarf around his neck. His chest and stomach are mostly exposed. He wears a blue belt similar to that of Piccolo's with white pants, and brown pointed boots, which are identical to Piccolo's and the other Namekians.
In both the anime and manga, Frieza says that Nail's power level is 42,000 after using his scouter to analyze him. Nail's power level of 42,000 is 18,000 higher than even Vegeta's initial level of 24,000 on Namek, arguably enough to put him on par with some members of the Ginyu Force depending on perspective. His level is so high that Frieza is astonished at the reading, and even says to himself that he would have liked to have him join his forces if he could. In the Dragon Ball Z The Anime Adventure Game, Nail's power level is 400,000.

Dragon Ball Z (Anime)
Namek & Frieza arc
When Dende takes Kuririn to Guru's home to get his inner powers unlocked, Nail is there, who greets Dende and Kuririn. Later on, while Son Gohan is getting his hidden powers unlocked by Guru, Vegeta arrives to collect a missing Dragon Ball. Nail confronts him and is ready to fight, with both of them insulting each other harshly. Gohan emerges with his newly unlocked powers before Nail and Vegeta had the opportunity to battle. Nail then senses five high power levels, which turn out to be those of the Ginyu Force. Guru orders Nail to go help the earthlings combat the Ginyu Force, but before Nail arrives, he turns back to continue assisting Guru, to protect him from Frieza, who came to know what is needed to say to make the Namekian Dragon rise from the Dragon Balls.
Nail distracts Frieza and battles him in order to stop him from killing Guru, and from obtaining the secret password needed to activate the Dragon Balls for immortality. Due to Frieza having a minimum power level of 530,000, which is roughly twelve times that of Nail's. Nail is no match for the tyrant and loses an arm which he regenerates during the brutal battle. Frieza toys with Nail, and threatens to torture Guru, while insisting that Nail must divulge the password needed to summon the Namekian Dragon, Porunga. Before Frieza deals the final blow to Nail, Nail lets out a small smirk, and reveals that this fight was only a diversion to delay Frieza, so that Dende could get the Namekian Dragon Balls' password to the Earthlings. Enraged, Frieza immediately departs at full speed, leaving Nail to slowly die, broken and beaten.
Shortly afterward, thanks to the Namekian Dragon Balls, a newly resurrected Piccolo arrives on the planet and discovers the battered Namekian. Nail tells Piccolo that if Piccolo and Kami were one once, they would have beaten Frieza long ago. Nail asks Piccolo to fuse with him in order to increase his chances against Frieza, and at the same time save his life. Piccolo eventually agrees, after some questioning of Nail's motives, wondering if his personality will still be the same, to which Nail assures Piccolo his personality will not change, and he will still retain control. After they fuse, Piccolo's power level increases dramatically to the point of being even with that of Frieza's second form, and possibly even stronger since Frieza made the decision to use his second transformation immediately after Piccolo removed his heavily weighted clothing.
In the English version only, when Piccolo fought second form Frieza. Piccolo revealed to Frieza that the two had fused while using Nail's voice. Later, when Dende is killed by Frieza in his final form, Nail as Piccolo's thoughts, was shocked and saddened. After everyone on Namek was brought back to life and transported to Earth, Dende finally realized that Nail had merged with Piccolo.

Later, Nail was heard via Piccolo's telepathic thoughts when Dende returned to Earth as its new Guardian during Cell's reign.
