Dark Matter Gunner

 is an alien, member of the Dark Matter Thieves. His role in the ship is to control most, if not all, of the cannons in the ship. He mostly awaits Geryuganshoop's orders hanging in the artillery room.

Appearance
He has the appearance of a middle aged man with a full-body costume with the costume being pink in color and spotted with blue circles. Apparently, he has no neck and three eyes are joint with his head.

Personality
He has a cowardly nature as when the ship was hit one time, he was already ready to escape. The second time, when Tatsumaki hit the ship with debris of City A, he was cying out and when he discovered that Boros's ship power core was destroyed he was calling out his mama.

Alien Conquerors Arc
He destroyed the city with the ships firearm. He was shown, in the manga, handling the gunner post. After Geryuganshoop ordered him to prepare the cannons for the S class fighting Melzargard, he did, but even after not receiving any order to fire, he attacked anyway. The bullets were stopped by Tatsumaki, who sent them back to the ship and he was visibly concerned about it. He is shown again when Tatsumaki throws the city's debris to the ship. Losing his self control, he was crying upon finding out that Groribas was dead. The third time he was shown, was when the ship's power core was destroyed. He then lost all his hope and was calling out his mama. After the ship crashed, he didn't show up with the "captured" prisoners by Superalloy Darkshine thus he likely died because of the crash.

Abilities and Powers
He has shown no special abilities. He can operate most of the cannons in Boros's ship.
