Grapple and Hoist ally themselves with the Constructicons.
Grapple shows Hoist a working model of a Solar Tower he wants to build and the two of them take it to Optimus Prime. Optimus is occupied at the moment because Spike is teaching him how to play basketball. Optimus likes Grapple's concept, but rejects the plan because it would be difficult to defend the tower against attack.
The conversation is cut short when Teletraan 1 alerts them that Powerglide has been shot down by Starscream and Skywarp. Hoist and Grapple leave to repair the Autobot plane. On their return, Grapple tries to convince Hoist to build the tower with him, regardless of Prime's orders, but Hoist isn't going for it.
Their conversation is cut short when they are trapped by the Constructicons. Scrapper says they've left the Decepticons and proposes a joint project. Grapple, enamored with his solar tower idea, agrees, but wants proof of their partnership. They promise to bring proof back and fly off.
On their return to Decepticon headquarters, Megatron confronts the Constructicons with video tape of their conversation with Grapple. They all swear loyalty to Megatron, and insist they plan to betray the Autobots. Satisfied with their explanation, Megatron lets them go with a present. They return to Grapple and Hoist with "proof," an entire truckload of energon. Convinced that they are working in good faith, Grapple and Hoist agree to the partnership.
Meantime, Optimus is playing basketball with Tracks, Inferno and Smokescreen. After he shuts Tracks down during a drive to the net, Prime notices that Tracks needs maintenance, but no one knows where Hoist is. The Autobot leader sends Powerglide out to find the missing Autobots. Powerglide finds the solar tower and reports back.
Grapple is in his element, directing the Constructicons as the tower is built, and blissfully unaware of their deception. The Constructicons merge to form Devastator in order to place the sun-focusing sphere at the top of the tower. With the last piece in place, the tables turn. Megatron attacks Grapple and Hoist and claims the tower as his own. The Decepticons get to work collecting the energy.
The Autobots arrive and attack. The Constructicons form Devastator and fight back. Prime tricks Devastator into trying to kick Smokescreen but he kicks the tower instead. A few more rounds of laser fire send Devastator crashing into the tower, demolishing it. Megatron and the Constructicons retreat.
The Autobots dig in the debris to try and find Grapple and Hoist. Brawn discovers them encased in a sheet of metal and punches it apart. Grapple and Hoist apologize for the trouble they've caused. Prime is in a forgiving mood, but says they have to clean up the mess themselves. As the others drive off, Grapple and Hoist fondly remember the tower.

Animation and/or technical glitches
- Near the end, when they're about to dig Hoist and Grapple out of the rubble of the solar tower, Cliffjumper is given Bumblebee's colors; although he doesn't speak you can recognize it as Cliffjumper by the spoiler across his chest.
- When the Autobots are approaching the Solar Tower, Inferno is not to be seen at all, when they finally transform to robots, one of the first shots shows Inferno, but none after. Probably meant to have been Ironhide in that shot.
- While welding a segment of the tower, Hoist's legs are colored black for a while then returned white.
- If energon cubes explode upon impact, how come they did not do so when Hook dropped them?
- When remastered for DVD by Rhino Entertainment, the re-created title card for the episode was incorrectly rendered as "The Master Builder." This title appeared on all associated material included with the DVD set, and can be seen in the screen shot above.
- This is the first episode not to feature Soundwave.
- Apparently random rocks are equipped by the Decepticons with video cameras.
- The Autobots shoot lasers out of their headlights when they drive into battle, yet that idea never crossed their minds in "The Autobot Run".
- Megatron has a compartment in his chest that holds a pair of binoculars. Well, if he doesn't have a Matrix to store in it, at least he can put it to good use!
- Megatron gave the Constructicons his Energon because he says that its the most important thing to him. Was anyone else expecting the fusion cannon?
- Seriously, can you imagine the size of the ball that the Autobots need to play basketball?
- How did Devastator's hand get way over there?
- One of Devastator's lines sounds suspciously like, "Tough luck, bitches!", but the low audio makes it uncertain (he's actually saying "A trap it is").
- When Teletraan I alerts the Autobots of Powerglide's attack, it is coded as "Condition: Magenta."
