The Skrall assault warrior is a special glatorian for Roxtus. He is armed with a torch you can't see because it was cut off, and an assault rifle.
(Note: I'm not a fan of Bionicle guys, so don't invite me to your bionicle groups. I was a fan of bionicle a long time ago and I found these creations in my old bionicle box. And I decided I want to show these to you guys. Even Though I still know the story.)
