Dinobot Island, Part 1

Powerglide and Bumblebee discover a hidden island where prehistoric creatures and time anomalies run wild.

Bumblebee and Powerglide are dispatched to investigate mysterious energy readings emanating from the sea. What they discover is an island filled with lifeforms thought to be long extinct, including dinosaurs. Further investigation is cut short, however, when the Autobots are attacked by the natives, and they decide to retreat.

Returning to the base, they inform Optimus Prime and the Autobots of their findings. Spike is fascinated, but Cliffjumper dismisses it, what with the problems the Dinobots cause them. Wheeljack defends the Dinobots, and brings Grimlock out to show them.

Grimlock displays his "finesse" by using his fire breath to turn on Blaster, impressing Prime and causing Ironhide, Trailbreaker, and Sideswipe to grimace in pain. Hearing the commotion, Slag and Sludge investigate, and cause Grimlock to mess up, sending his fire breath all over the place.

Grimlock angrily orders his subordinates to go away, but Sludge steps on Slag's tail, causing him to breathe fire. Snarl and Swoop also come to investigate, and the Dinobots collide with each other, resulting in a brawl. Teletraan I is nearly destroyed, but Trailbreaker's force field manages to protect the computer, while Red Alert and Inferno put out the fires.

The Autobots are prepared to fight the Dinobots to a standstill, but Optimus orders Grimlock to bring the other Dinobots under control. Grimlock succeeds, and apologizes to Prime. The Autobot leader accepts, but also realizes that the base is too small for the Dinobots to train in, and decides to have Powerglide lead them to Dinobot Island, as Spike has called the island. However, Ravage overhears this, and Soundwave sends Laserbeak to follow them.

Arriving at the island, the Dinobots are impressed with the wide open spaces. However, Spike gets into trouble with the local fauna, nearly getting eaten twice. Spike decides to go home with Powerglide, while the Dinobots work on their skills, such as Slag's "fire stuff", Snarl's "tail stuff" and Swoop's "flying stuff". However, Laserbeak reports his findings back to Megatron, who decides to plunder the island's multiple energy sources.

Spike, having had enough of real dinosaurs, decides to check out some books with Bumblebee. However, while at the library, they see a temporal distortion, out of which comes barbarians riding woolly mammoths. They begin randomly attacking things, destroying the library and burying Spike and Bumblebee under a ton of rubble. At Dinobot Island, the Dinobots discover the Decepticon presence, and attack. However, Megatron causes the native dinosaurs to stampede toward the Dinobots, causing them to fall into a tar pit, which they sink into.
