Grabenkämpfe is a German, and a member of the Mahziis. He was recruited by Weegee and Zweegenod. He was originally just a member of the normal soldiers. However, Malleo notices that his battle tactics were very unique, and was an expert at Trench Warfare. After a short time, Grabenkämpfe was promoted. He lead a tiny squadron that specializes in Trench Warfare just like him. His catchphrase is "Get out of mah trench!".
- His name was specially chosen, if it is translated it becomes apparent why.
