German Hammer was a competitor robot which attempted to enter Series 7 of Robot Wars. Entered by father and son team Stefan and Phillipp Trenkle, it failed to qualify for that series after losing its qualifier to Supernova.

German Hammer was an invertible, box-shaped robot painted grey and featuring four-wheel drive. Its main weapon was a cutting drill, which proved fairly ineffective in its qualifier, serving mainly to bypass the active weapon rule required for all Seventh Wars competitors. Otherwise, the robot focused purely on ramming with its static spike. It had three stars painted on it, each in one of the colours of the German flag.

In its Series 7 qualifier, German Hammer fought Supernova, Hammerhead 2, and Splinter, who withdrew before the battle began.[1] German Hammer lost the battle after sustaining severe damage from Supernova, eventually becoming immobilised mid-battle. As a result, German Hammer lost its qualifier for the Seventh Wars and did not receive an invitation to compete in the series.
