The General told the soldiers to fly straight at the Photon Lab to personally see the its destruction. It met up with Mazinkaiser after it destroyed the Warrior Beasts and Generals that were station there. It tried to ram the Mazinkaiser into Mt. Fuji hoping to crush it. But soon the Mazinkaiser activated its Mazin Power to overpower it. Mazinkaiser then used its Kaiser Boomerang to cut the Demonika in half. Before this the General escaped from a saucer on the top to face Mazinkaiser himself.
