Mauer was a Mars Kingdom Parliament Army soldier who was part of Alpha Team during Operation Hagel, a joint military operation to recover Olympus Spaceport from the Neo-Third Reich Division. During the operation he was killed by Frau X.
Mauer's most notable feature was his mantis-like head, which had antennae and a pair of large, multi-directional eyes. During Operation Hagel he wore Mars Kingdom Parliament Army combat fatigues.
A month before the Tenth Zenith of Things Tournament, Mauer was attached to Zazie's Alpha Team during Operation Hagel. He used an aerial drone that flew over the battlefield to relay combat intelligence. After Alpha team secured the November Dome in cooperation with Beta Team, they were sent to provide backup to the Venus Foreign Legion's Squad Q. When Mauer sent his drone to scout ahead of the rail car that Alpha Team was riding on it, it located Frau X riding on Squad Q's flaming car coming towards them. After she destroyed the drone Zazie gave the order to fire on the rail car in response. This caused Mauer to plead with her not to shoot before uncharacteristically jumping in front of Kong's portable missile launcher just before he fired, claiming that Frau X was his "angel". Mauer was killed when the rocket propelled him onto Frau X's rail car and destroyed it. It is suggested that Frau X may have hacked him into doing this.
