The Monster Association start their invasion and Elder Centipede is ordered to grab the hero Association sponsor Narinki and his son Waganma as hostage, but Metal Bat stops the monster and the two begin to fight. Metal Bat has the upper hand in the fight, however Elder Centipede manages to shake Metal Bat off by maneuvering around the city, which sends Metal Bat flying across the city.
Metal Knight arrives and launches several missiles at Elder Centipede, causing pain to the monster. Elder Centipede notes that Metal Knight is just a pest, but the hero is intrigued by the monster's hard shell, wanting to get a sample of it to develop new weaponry. Metal Knight orders Mohican and Pineapple to leave the place, since he plans to test his weapons in the surrounding area.
Metal Knight battles the monster using his missiles, but Phoenix Man orders Elder Centipede to retreat, as they have achieved their objective, and Elder Centipede grabs Phoenix Man and Rhino Wrestler, leaving through the hole he created earlier. Metal Knight refuses to allow the monster to escape and uses his Metal Knight Unit to grab onto Elder Centipede to follow Elder Centipede while he is leaving.
