Nail

Nail is a Namekian warrior from the Dragon Ball Z anime (Namek Saga). He is portrayed as the last and strongest remaining Warrior-type Namekian on Planet Namek at the time, serving as the dedicated personal bodyguard to the Grand Elder Guru.

Physically, he looks almost identical to Piccolo (same facial features, height, and build), but wears distinct clothing: a blue vest, white scarf, flowing brown vest leaving his chest mostly exposed, baggy white pants with a blue sash, and typical Namekian pointed brown boots.

In personality, Nail is heroic, honorable, calm, serious, and deeply loyal — fully committed to protecting Guru and his people. He demonstrates courage and self-sacrifice, notably by engaging Frieza in battle (despite the massive power gap) to buy time for others, even regenerating a lost arm during the fight.

After being severely injured by Frieza, he convinces a newly arrived Piccolo to fuse with him (Namekian assimilation), permanently merging to boost Piccolo's power significantly against Frieza — allowing Nail's strength and consciousness to live on as part of Piccolo.

He's a supporting character who appears mainly during the Namek/Frieza arc in the anime.
