Warrior Ing are powerful foes, exercising fusion attacks, along with various kinetic offensives and trans-dimensional laser blasts. At close range, their razor-sharp limbs serve as weapons. They can change into their gaseous form (the "Black fog") at will, in order to possess other organisms. Warrior Ing are also able to transform into a liquid state, allowing them to traverse any surface with ease. When these "shadows" are struck with light energy, their moving speed will dramatically increase.
Warrior Ing, like several other types of Ing, feature a large, singular eye containing a cluster of glowing red particles in its body. Unlike the other members, the Warrior eye bears a stronger resemblance to a compound eye (with the red particles being individual 'eye' units).
Eleven Warrior Ing attacked Samus in the Phazon site at the beginning of the game, with six of them stealing her upgrades and later using them against her in some shape or form: those that stole the Space Jump Boots and Boost Ball without possessing another creature were featured as bosses and had been slightly mutated by the items; they were the Jump Guardian and Boost Guardian. The other four Warrior Ing ultimately end up possessing creatures (an Alpha Sandigger, a Grenchler, a Pillbug and a Sporb, respectively). They are all killed by Samus later on.
"Morphology: Warrior Ing. The soldiers of the Ing Horde. Shapeshifting wallcrawler. Dangerous combatant in melee and at range. Dislikes bright light. Warrior Ing are challenging foes. They can render themselves into amorphous puddles and move over most terrain, including walls. Warrior Ing's can turn their bodies into dangerous projectiles sheathed in dark energy. The tips of their legs are razor sharp, making them formidable in melee. Finally, Warrior Ing are capable of channelling transdimensional energy and firing it at their enemies. Their only real weakness is bright, pure light, which they hate and fear."
The Warrior Ing were the first pure Ing that Samus encountered, and they were also the last: as Dark Aether was collapsing after collecting the last of Aether's planetary energy from the Sky Temple, several Warrior Ing attempted to stop her from reaching the only available portal. Samus Space Jumps over them and reaches the portal. When she returns to Light Aether, the legs of several Warrior Ing are seen trying to get through the portal. However, they don't get through in time and die with the dark world.
If a Warrior Ing is damaged just before it begins to shift from liquid to solid form, the liquid will remain bright red throughout the transformation.
