Fantastic Four #208

THE POWER OF THE SPHINX! Thanks to the intervention of Nova (aka Richard Rider) and his friends the Skrulls' attack on the planet Xandar has been temporarily halted, but now the Fantastic Four have another problem...the Sphinx! The Egyptian villain has tapped into the living computers of Xandar and gained enormous power. Fortunately, the Human Torch has linked up with his teammates, and now the entire Fantastic Four plus Nova, Comet, Crimebuster, Diamondhead, and Powerhouse will battle the Sphinx! Meanwhile, Reed, Sue, and Ben are beginning to the feel the effects of the Skrull aging ray.
