An unstable volcano at a Caribbean resort holds vast reservoirs of energy. Decepticons, Predacons and Autobots clash at the resort, with the volcano reaching erupting point.
The Build Team, a squad of rookie construction-worker Autobots, get their first mission - stop the Predacons at Antarctica. This job becomes more difficult than it sounds.
The Deceptcions challenge the Build Team to a duel, for their space bridge network. Optimus Prime cautions them against it, but they defy orders and wind up over their heads again.
A massive battle takes place for the Orb of Sigma, a glowing sphere of power. The Autobots win... but as a consequence Megatron is reborn as Galvatron.
The key to controlling the titanic Fortress Maximus is the bio-force from a human. The only Transformer who has this energy is the Deception Scourge...
