The Dark Matter Gunner was an alien and a member of the Dark Matter Thieves and was the gunner of the giant spaceship. He was killed by Sweet Mask.[1]


The Dark Matter Gunner was a fat humanoid creature with pink skin spotted with blue circles. He had two eyes on his face and three tentacles on his head that each contain an eye.


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 the debris of A-City, he was crying out and when he discovered that Boros' ship power core was destroyed he was calling out his mama.


Hero Association SagaEdit

Alien Conquerors ArcEdit

He destroyed the city with the ships firearm.[2] 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 in the manga and webcomic, he didn't show up with the "captured" prisoners by Superalloy Darkshine thus he likely died because of the crash. Meanwhile in the anime, he was one of the "captured" prisoners, but was swiftly executed by Sweet Mask.

He could operate most of the cannons in Boros's ship but showed no special abilities.
