The Fantastic Four return with a new issue #1, kicking off a whole new volume of their adventures through time, space, science, and the human condition! When the Fantastic Four take on Doom, things go well until they suddenly go catastrophically wrong — and they're sent to four different eras in Earth's history! Alone and isolated in wildly different time periods, Reed, Johnny, Ben, and Sue all have to fight to survive. Their only hope is to reach the Forever Stone: a mass of dense granite that happens to be one of the longest-lasting rocks on the planet, which — through a combination of obscurity and raw geological luck — has stayed both intact and accessible for most of Earth's history! Also featured in this extra-big, extra-special issue: Ben Grimm fights a dinosaur! No other comic DARES to feature the Thing battling several Mapusauruses, but that's just where WE get started! And it's all brought to life by the incredible new series artist Humberto Ramos! LEGACY #727
