Resumen:
The Autobots manage to escape, but have no choice but to leave
Sparkplug behind. They hide in Wheeljack's lab, where they began to build a
device that would free the slaves from the hypno-chip's control. On Earth,
Optimus Prime and the rest of the Autobots arrive at Megatron's energy-
generating base as they await the oncoming tidal waves. On Cybertron,
Wheeljack is able to use his device to free Sparkplug and escape back to
Earth. The Autobots follow Megatron to his island outpost as the slaves load
his starcruiser with the newly created Energon cubes. Megatron discovers
Starscream's deceit once more as he tries to develop his own way of creating
Energon. He escapes Megatron's wrath as the Autobots attack. Wheeljack frees
the remaining slaves with his device while the Autobots defeat the
Decepticons. Megatron makes a last ditch attempt to escape on his starcruiser,
but is shot down by the Autobots, with the Energon on board exploding and
forcing Cybertron back out into orbit. The Autobots recover as Megatron floats
through space awaiting his revenge.
