Ultimate Fantastic Four #21

All four members of Marvel's Ultimate Fantastic Four charge forward in this 2005 opener to the "Crossover" arc — Sue Storm leads the advance in her sleek uniform, flanked by the rocky mass of the Thing, while Mr. Fantastic stretches above and the Human Torch blazes across the background in a burst of flame. Cover artists Greg Land and Matt Ryan give the team a genuinely dynamic presence, every figure radiating purpose and urgency. With Mark Millar at the helm, "Crossover Part 1" promises exactly the kind of ambitious storytelling that made this series one of Marvel's most talked-about runs of the era.
