The N'kren are a starfaring race mentioned only in Luminoth Lore in Metroid Prime 2: Echoes. It is likely that they also met with the Chozo, Ylla and Reptilicus. Like the Ylla, they have yet to be seen in person in the Metroid series.

Luminoth Lore (Origins)[]
"It is told that the Luminoth were not born of Aether, but of the stars. In the early days, we roamed the greatness of the void, bathing in the glorious light of a thousand stars. We met a vast number of enlightened minds... the N'kren, the Ylla, and the Chozo among them. Each of them, we found, had claimed a homeworld and formed a deep bond with it. In time, we decided to do the same."
