Auto Berserk

Battle damage fries Red Alert's logic circuits, and the paranoid security director teams with Starscream against his own friends.

After the Autobots successfully test a new super-weapon called the Negavator, they are attacked by Soundwave and the cassettes, who attempt to steal it for the Decepticons. While most of the Autobots exit the bunker to fight, Red Alert stays behind to guard the facility and operate the Negavator. At first, Inferno stays to protect Red Alert, but he is eventually lured away by the call of battle, despite Red's protestations. Defeated, the Decepticons retreat, but not before Rumble fires a rocket into the control room, which causes the console Red Alert was operating to explode. The Autobots return to assist him, but the odder-than-normal Red Alert brushes off their help, accusing Inferno of betraying him. However, Red Alert's injuries go deeper than the surface. His logic chips have been affected, and he begins to feel as though everyone is against him.

As the Autobots escort the Negavator back to Autobot Headquarters, the Decepticons launch a sneak attack in a ravine that Red Alert does not detect due to his insecurities and his damaged state of mind. Optimus Prime and Ironhide are buried under the rubble caused by Rumble's landslide while the Decepticon jets attempt to take on the remaining Autobots, only to be thwarted when Smokescreen sprays a dark cloud of exhaust over them, obscuring their sensors and causing them to crash. With the Decepticons defeated a second time, Megatron retreats, leaving Starscream behind. When Optimus Prime questions Red Alert about his lack of a warning on the attack, Red instead accuses the Autobots of wanting to do away with him and runs off at the suggestion that they repair his logic circuits. Starscream, observing this turn of events, follows Red into the city.

As the other Autobots try to find Red in the city, Starscream successfully gains the trust of the paranoid Autobot by sharing his similar situation, and together they form a partnership to steal the Negavator and bring both Optimus Prime and Megatron to account for their respective betrayals. Meanwhile, the Autobots have brought the Negavator back to the bunker and secured it in the lowest level while they recharge. Hoist and Inferno are concerned that Red Alert's logic circuits will explode if they do not find him soon. Red leads Starscream to a secret entrance into the bunker, but they are unaware they are being observed by Ravage and, in turn, Megatron, who seems to be content to let the pair of traitors do the dirty work for him.

Inside the bunker, Red Alert and Starscream narrowly avoid death at the hands of the tunnel drone, but manage to set off the alarms in the process, alerting the Autobots. Commandeering the Negavator, they blast their way out of the holding chamber and use the elevator to arrive on the top level. Awaiting them are the other Autobots, who mistakenly believe Red Alert is some kind of hostage to Starscream until he tells them their intentions. At this point, Megatron and the other Decepticons enter, causing a sputtering Starscream to agree with Megatron that he was merely delivering the weapon to his leader. When Red Alert realizes Starscream's duplicity, he attempts to fire the Negavator, only to be pulled out of the cockpit and blasted with the Decepticon's null-ray. The null-ray blast serves to stabilize Red's logic circuits, unbeknownst to the Decepticons, who attempt to force him to use the Negavator on the Autobots. Unfortunately for Megatron, Red Alert instead sets the self-destruct mechanism on the superweapon, causing the Decepticons to flee.

The Autobots run as the Negavator explodes. Discovering that Red Alert is still inside, Ironhide, then Optimus Prime attempt to enter the blaze to save their friend, but Inferno insists on doing it himself, perhaps as penance for his earlier desertion of Red. Inferno saves Red Alert from being crushed even as the remorseful Red tells the gun-slinging fire truck to leave him behind. Outside, the other Autobots cheer as Inferno carries the injured Red Alert out of the flames. Red attempts to apologize for all the trouble he has caused them, but Optimus Prime is the one who accepts the blame, for it was his insistence on testing the Negavator that started their problems. Prime declares they are glad to have Red Alert back, and commends both him and Inferno for their bravery. Red replies that with friends like the Autobots, it's easy to be brave.
