Namekians are a green alien species featured in Dragon Ball Z consisting entirely of males. Hailing from the planet Namek, their general appearance consists of green skin, pointy ears, and antenna with a lack of any hair. As youths, their muscles often feature patches of pink musculature, which turns yellow as they grow older. They are referred to by many as "Slug people".
Namekians tend to come in two varieites: Warrior Clan Namekians, which have high power levels and proficiency in battle, and Dragon Clan Namekians, which are capable of healing injuries and creating or recreating Dragon Balls. Very rarely, a Super Namekian is born, one with exceedingly high power. In the past, there was also an Albino species of Namekians, although by present day they are extinct.
They can regenerate any injured or lost part of their body as long as their head remains. A special few can create Dragon Balls. They give birth by spitting out eggs, which hatch eventually. As a result, they lack reproductive organs of any sort. They can connect to the internet with their antennae, and can also use this ability to install apps.
Though the practice is forbidden, Namekians can fuse permanently with one another to beome more powerful. A Namekian fusion is initiated by two willing participants, with the Namekian that will become the host placing their hand upon the other, either on the chest or lower down. After a flash of light, the two will have merged, with the subconscious personality vanishing inside the host Namekian's mind. Given enough time (and presumably a willingness or desire to do so on behalf of both the host and the subconscious personality,) the subconscious personality is said to fade into the subconscious, effectively leaving the host with only a boost in power. A subconscious personality in a Namekian fusion can access an internal "inner world" of sorts inside the host, where objects such as pool tables can exist and be interacted with by the personality. Said personality or personalities can interact with their host, serving as a parallel voice inside the host's mind. Fused Namekians also seemingly give off merged yet clearly identifiable Ki signatures, as both Dende and Super Kami Guru could recognize and subsequently identified Piccolo as Nail, though neither seemed to notice or object to their use of the forbidden technique.
They used to have a close relationship with their albino cousins, until the Eldest Namekian Guru ordered a genocidal strike upon them. Guru declared their genocide was due to them being the cause of the Great Drought which devastated their people, although this was merely done to hide the fact he himself had caused the drought by drinking the entire planet's water supply.
- In the original series, the entire population of Planet Namek were the sons of Guru, as he had repopulated the entire planet after the disaster which devastated the planet. In Dragon Ball Z Abridged however, there were smaller families of Namekians with fathers and sons, based on the early 90s dub of the original series which made the same change.
- Namekians do not eat food, with their diet consisting entirely of drinking water. Given Super Kami Guru recoiling at natural light, Namekians most probably do not make use photosynthesis. If a Namekian drinks an obscenely large amount of water, as Super Kami Guru did, they willl become chronically obeese but potentially functionally immortal, as seen by Super Kami Guru's revival from intentionally stopping his heart and seeming inability to naturally pass on before his brutal mauling by his enraged people.
