Resumen:
A small force of Autobots who were deactivated by Superion rather than
infected are rebuilt by the Quintesson. Bumblebee is rebuilt into Goldbug.
The Autobots must get the Matrix from Rodimus, and they need the metal
Galvatron stole to protect Optimus from infection. They locate Galvatron, but
nearly all of the Autobots and Galvatron are infected in the process. Optimus
gets the Matrix from Rodimus, but the remaining Autobots are infected. He enters
the Matrix and uses it to cure everyone, but the knowledge of the Matrix has
been lost in its use.
