The I remembered Kongu, and without better idea, began working on a revamp. I made the hands similar to ones of Ragnfast the Viking to make him hold a gun. I also added some a bit more extreme tubing on his "breathing apparatus". Story-wise they don't need breathing apparatuses, as they can breath underwater, so I thought they would contain some anabolic steroids to keep him "fit".
I also gave him cooler gun than those ugly one-piece blasters. I had had that barrel idea for some time, I'm very happy with it, and now I had a proper chance to put it on use. The gun isn't really a Gatling gun, but still powerful enough to keep those nasty Barraki on a distance.
