Nail

ネイル

Nail is a Namekian who appears identical to Piccolo, with the exception of his attire. He is characterized as the sole remaining "fighter class" Namekian. He serves as Guru's personal bodyguard and possesses considerable strength for a Namekian.
During the Captain Ginyu Saga, Nail engages Frieza in combat to prevent him from killing Guru and seizing the Dragon Balls. Although Frieza was at his lowest power level of 530,000, Nail could not match the tyrant and even lost an arm (which he regenerated using Regeneration) during the fight. Before Frieza could kill Nail, Nail disclosed that the battle was intended to delay Frieza, allowing Dende to provide the Namekian Dragon Balls' password to the Earthlings, Gohan and Krillin. Enraged, Frieza immediately departs, leaving Nail to die on the ground.
Shortly thereafter, a newly resurrected Piccolo arrives and discovers the incapacitated Namekian. Nail retains the ability to speak and requests that Piccolo fuse with him to improve his odds against Frieza and simultaneously save his own life. Piccolo agrees after questioning Nail's motives, and his power level indeed rises dramatically, becoming more than sufficient to match Frieza's second form.
