Hunter Ing are powerful Ing with a phasing ability that allows them to easily avoid attacks as well as ambush targets. They patrol Dark Aether for enemies of the Ing and are relentless, prepared to seize their prey or die trying. Hunter Ing are the only Ing allowed to possess Pirate Commandos and they will fight amongst themselves for that right. They are also the primary predators of Nightbarbs.
Samus encounters Hunter Ing in multiple areas throughout Dark Aether, usually in pairs. While they do share their weakness to the Light Beam with other Ing, they are easily capable of dodging it. Samus can target them with the Dark Visor while they are phased, but she is incapable of damaging them. Hunter Ing will also dodge any charged attack. They are highly susceptible to Super Crystals.
- "The Hunter Ing patrol the lands of Dark Aether in search of the Horde's enemies. They can render their bodies intangible, allowing them to ambush their targets with ease. Hunter Ing can generate long, deadly tentacles, which they use with great effect in battle. Cunning and relentless, the Hunter Ing will seize their prey or die." — Logbook "Hunter Ing" (Metroid Prime 2: Echoes)
- "The Ing prize the few Pirate Commandos they manage to take alive. Only Hunter Ing are allowed to possess the Commandos, and the competition for that right is fierce among them. The Hunter Ing ability to phase out of local timespace carries over to the Dark Pirate Commando. They will fire bursts of dark matter at enemies, along with experimental EMP grenades stolen from the Space Pirates." —Logbook (Metroid Prime 2: Echoes)
- "Nightbarbs are small airborne darklings. Smaller and weaker than a Hunter Ing, a Nightbarb will travel with a large pack to increase its odds of survival. This is wise, since their primary predators are Hunter Ing." —Logbook (Metroid Prime 2: Echoes)
