Ultimate Fantastic Four

A group of superpowered individuals with unusual speech patterns break into the FF's reality in a rather violent way. In the ensuing fracas, they loose "Seed," a device which serves as a translator and more. They follow it back to the Baxter Building, where Reed and Sue took it (and their vehicle) after the combat. Once there, they use their abilities to walk through the Baxter Building with little or no resistance.
