The Microwave Cannon is a powerful laser built by the Pilon Corporation as their first manufactured weapon. The system that activates it was hacked by Neo Terror.
When Neo Terror didn't construct a Zukkein , they decided to use the Microwave Cannon. The Microwave Crisis Card allowed Maen to bring out the weapon. Rescue Force was alerted of the situation. Rescue Max Drill-Dozer was formed and tried to dodge the laser's blasts and rescue the people in the Development Department building. Altough the mech suffered from the Microwave Cannon's shots, it was able to succeed in its rescue.
Pilon Corporation gave permission to destroy the weapon to Rescue Force. Rescue Max Drill-Dozer then obliterated the Microwave Cannon.
