DC/Marvel: The Flash/Fantastic Four

It’s DC/MARVEL: The Flash/Fantastic Four! The Fantastic Four are coming back to the Baxter Building after a mission on Saturn, when they are surprised to find Gorilla Grodd scaling the building, with The Flash (Barry Allen) hot on his (non-existent) tail! Grodd is after Reed Richards’ mental amplifier tech, and using The Flash as his unwitting (mind-controlled) ally, tries to break into FF headquarters to steal whatever he can get his grubby little paws on, taking both teams on an adventure through time and space!
