'The natural enemy of the robot is hippies!' Stockade ordered Major Mayhem to scan the cache to confirm Drift's claim, only to find the Autobot was bluffing. Drift was the first to respond, claiming that the cache he was holed in also contained a doomsday device, which he would activate should the Decepticons continue their assault. With the Autobots trapped in three separate locations, Stockade gave them an ultimatum surrender the weapons or be destroyed. Though the Mini-Cons were successful in both splitting up the Autobots' forces and injuring Drift, the enemy managed to seal up the cache once more, putting it again out of Stockade's reach. Once Windblade and the rest of the Autobots' stealth team arrived to investigate, Stockade ordered his troops forward.

Finding themselves unable to penetrate the cache's defenses, the small army instead lay in wait for the Autobots to respond to the base's security alert. Several platoons of Mini-Cons led by Major Mayhem accompanied Stockade in an attempt to break into one of Windblade's many weapon caches on Earth.
