Outta the way, here's comes Rex! Season 1 of GENERATOR REX starts off with a blast when Rex takes down an Evo monster by getting all up in his face. Then he barely escapes falling prey to the evil Van Kleiss and winds up crushing on a cute Evo girl who turns out to be a secret agent. Maybe it would all be easier if Rex had some clue about his past. Then again, Rex doesn't do easy.
