Resumen:
The Decepticons discover a chasm full of crystals that destroy
machinery, and they create a machine that can duplicate Transformers. The
Decepticons duplicate Optimus Prime and confuse the Autobots as to who
is the real Prime. The Autobots and Decepticons fight near the chasm, and
the duplicated Prime destroys a duplicated Starscream to further confuse
the Autobots. The Autobots are just about ready to follow the fake Prime
into the chasm when he (controlled by Megatron) breaks the masquerade by
not showing any concern for Spike's welfare. The Autobots knock the fake
Prime into the chasm, and the fake Prime is destroyed. The Decepticons
abandon their desert base in this episode.
