Resumen:
While Ultra Magnus and Scattershot are investigating some strange
seismic activity in Peru, the Cybertron Headmasters send Steeljaw and
Ramhorn to find out what's inside the black nebula (from the last
episode). Inside the nebula is a planet where enslaved Battle Beasts
are used by Scorponok to build a massive construct. In the Andes, a
dormant volcano suddenly erupts, and the Protectobots and Trainbots
are sent to rescue the people living nearby. They are confronted by
the Predacons and the Destron Headmasters. The other Cybertrons use
Broadsides to fly to Earth, drive off Predaking, and the Trainbots
evacuate the humans. In the nebula, Scorponok explains that the
volcano exploded so the Destrons can tap its energies while Ramhorn
and Steeljaw secretly listen. On Earth, the Destrons make one last
attempt to take the villagers hostage, but they are thwarted by the
Cybertrons. Back on Charr, Scorponok reveals part of his plans to
Cyclonus and Scourge; Ramhorn and Steeljaw record the information, and
forward it to the other Cybertrons.
