Fantastic Four #12

Aliens have invaded Earth and been rebuffed by the Fantastic Four many a time before, and finally, one of them got wise and invaded Earth where the FF couldn't defend it: They're attacking our world in the past, in ANCIENT ROME. Johnny and Reed are the only two who make it back in time before all of history is erased, but it's okay! As long as they can defend Earth, push the aliens back AND reset history to how it once was, everything should be fine, right? Good thing that, when left alone, Johnny and Reed don't get into ANY sort of problems on the regular. Plus: Reed stretches in a new way in this one! He does that in a lot of our issues, but this one is particularly fun.
