Fantastic Four #12

Aliens have attacked Earth many times and been repelled by the Fantastic Four every time. But this time, they get smarter: They attack our world in the past - in ancient Rome! Only Johnny and Reed make it to the past in time, before history is erased.

Now they have to defend Earth, push back the invaders and restore the timeline. Easy, right? Lucky thing that Johnny and Reed, when on their own, never get into trouble. Plus: Reed uses his powers here in a particularly new and fun way!
