In Metroid Prime 2: Echoes, Inglets are small Ing that serve as the Horde's labourers. They are not well-equipped for combat, but can still shapeshift into the characteristic Ing blob form, as well as fire a small chunk of dark matter to defend themselves. When they take a solid shape, their main body and/or eye seems to be a glowing red mass wrapped in black vines, a trait seen in other types of Ing. They often travel in large swarms, and are a nuisance for Samus as they sometimes inhabit places where her Morph Ball must stay attached to Spider Ball Tracks.
"Morphology: Inglet. Worker drone of the Ing Horde. Wall-crawling, morphing bioform. Strongly dislikes bright light. Inglets perform the menial labor of the Horde, but can be pressed into a combat role if there is need. They are amorphous blobs, capable of clinging to nearly any surface. Inglets can fire bursts of dark matter in self defense, though they prefer to avoid battle. They seldom travel alone, and can be dangerous in large numbers. As with all Ing, they dislike bright light, and will avoid it if possible."
The Emperor Ing's first form in the battle with Samus resembles an overgrown Inglet. Many fans speculate that the Emperor, the first of the Ing, was originally an Inglet before going through Phazon mutation.
The resemblance between Phaz-Ings and Inglets has caused an enormous belief among fans that the former are the ancestors to the entire Ing race. No official word from Retro exists, however.
Enemies heavily resembling Inglets have appeared in the game Legend of Zelda: Phantom Hourglass, sent after Link by the final boss, Bellum. Similar to the battle with Emperor Ing, it seems their main purpose in the battle is to be destroyed to provide ammunition and health.
