During the 1980s, Ladybird Books realised the potential in creating books based on popular franchises at the time. It was in this period, Ladybird published books based on He-Man, She-Ra and Action Force.
Megatron's Fight for Power was the second book published in Ladybird's first series of books. This first series was published in 1985. It was written by John Grant and illustrated by Mike Collins. The audio book was narrated by Peter Marinker. The books included voices of the characters, sound effects and even a version of the theme. The art style copies the toys and is based on the Marvel UK continuity.
The plot is As the Autobots continue repairs on their spaceship, the Decepticons begin a search for a new source of energy to power theirs. Buzzsaw is dispatched, and reports a faint radar signal outside of the distance parameters of his search, prompting Megatron to investigate things personally. He and Soundwave discover a government research laboratory experimenting with solar energy collection, and Megatron summons the other Decepticons. Starscream, however, sees this as an opportunity to overthrow Megatron and takes charge of the remaining Decepticons for that purpose.
Relaxing in the mountain, Ironhide tunes into the local radio stations, only to wind up stumbling across Megatron’s transmission. Racing back to base, Ironhide informs the Autobots, and Hound triangulates the Decepticons’ position. Optimus Prime heads out to investigate with Spike and Sparkplug.
Starscream, meanwhile, leads the Decepticons in his planned attack on Megatron, but mistakenly believes that the Decepticon leader is hiding within the laboratory building. In actuality, Megatron, suspecting such treachery, has hidden in the shadow of one of the solar saucers, and when Starscream offers mercy in exchange for surrender, Megatron blindsides him and quashes his short-lived rebellion.
Prime, Spike and Sparkplug soon arrive, and Spike attempts to sneak into the laboratory building to access the controls for the solar energy system. Finding the lab door to be locked, he signals to his father in Morse code by flashing light from the blade of his pocket knife, and Prime deploys Roller to deliver a sonic multi-tool to Spike. Almost spotted by Soundwave in the process, Roller delivers his payload and Spike is able to get into the laboratory. Redirecting the beam of solar energy, Spike targets the Decepticons’ pile of energon cubes and destroys it in a massive explosion. As the damaged Decepticons depart for their base, Megatron spies Optimus Prime approaching and vows vengeance as he too retreats.
RetroRobotRadio has uploaded the audio of the book with images of the novel. It's well worth a look and an interesting story, revolving around Megatron wanting an energon supply to fuel his cruiser.
