Resumen:
In the city of San Francisco, a giant man-eating plant suddenly
springs from underground, causing mass hysteria and major damage.
In response, Ultra Magnus sends out the Technobots, Aerialbots
and Trainbots to assist, but they are met by Bruticus, who battles
Raiden. Ultra Magnus contacts Fortress and the Cybertron Headmasters,
who then head toward San Francisco. They get beaten up by the
plant, mocked by the Destron Headmasters, then another plant shows
up, as well as another at the Witwickys'. Menasor then battles
Computron, while Bruticus takes on the Aerialbots. One plant monster
is actually able to walk, and it attacks the Cybertrons' earth
base while the other attacks Fortress' battle station. Fortress
then uncovers his sword of power and the base suddenly transforms
into a giant robot, Fortress Maximus! He manages to destroy the
plant monster, causing the others to blow up.
