The Trigger, Part 1

Tigatron discovers a floating alien island and the mystery of the precursors who seeded the planet.

An earthquake on a snowy mountainside raises questions from the nearby Tigatron, on his way to file his weekly report with the rest of the Maximals. Rattrap answers Tigatron's call, and as soon as Tigatron mentions that he hasn't seen any Predacon activity, Waspinator and Terrorsaur attack, their attacks causing Tigatron's communication console to collapse upon him as Rattrap listens. Optimus Primal heads out to rescue his comrade.

Tigatron, pushing the console off himself, continues to fight against his airborne assailants. A missile from Terrorsaur is detonated by a shot from Waspinator, tearing the ground into pieces and dropping Tigatron into a cloudy chasm. But when the two fliers follow Tigatron into the cloud to gather his remains as trophies, they are blasted by something unseen.

Primal eventually arrives at the site of the battle, and using Tigatron's communication console, radios to the Axalon that Tigatron is missing, possibly destroyed.

Airazor, spying on the Predacon base, witnesses Waspinator and Terrorsaur return in poor condition. The two goons report to Megatron what happened to them after they followed Tigatron.

Inside of the cloud Tigatron fell into, the two Predacons discovered Tigatron had landed on a massive flying island. While trying to finish Tigatron, the two were blasted away by energy beams from a strange tower in the center of the island. Megatron sends the team of Scorponok and Blackarachnia to claim the island in the name of the Predacons.

Airazor reports to the Maximals her observation of the two Predacons, who were badly damaged to the point of death. The other Maximals deduce that while Tigatron is against such brutality, he could still be alive. Cheetor rushes in to follow up her report with news that Blackarachnia and Scorponok are leaving the Predacon base. Airazor is sent to follow the two.

In beast mode, Tigatron explores the island he's discovered, and is amazed at the flora and fauna on the isolated paradise. But, after passing a rock with strange markings, the island reveals some strange defenses against his presence. Tigatron decides to play it safe for the rest of his time in the strange area.

Outside of the cloud, Blackarachnia and Scorponok find the island. Scorponok explores the island with one of his cyberbees, until Tigatron snatches the bee out of the air. The deceptive nature of the cloud confirmed, Blackarachnia fires a line into the cloud to board the island. As the line retracts, pulling up the two arachnids, Scorponok sees Airazor in pursuit. Using one of his rockets, he blasts her out of the sky. After Scorponok dodges the island's response to his attack, Blackarachnia resolves to take control of the island for herself.
