Marvel Fanfare Vol 1 #3

Argumento

Angel calls in the X-Men to help deal with Sauron in the Savage Land. Since Ka-Zar and Shanna had left for Pangea (Ka-Zar Vol 3), an alliance of Sauron, Zaladane, and Magneto's mutates was able to quickly conquer the land. The X-Men clash with the mutates and force a captured Amphibius to lead them to Sauron's fortress, but it turns out to be a trap as the fortress is surrounded by a will-sapping energy field that ensures they're quickly defeated and set to be devolved by mutates' machine to provide Sauron with an endless supply of mutant energy to drain. Only Angel escapes capture, but someone unexpected finds him instead...
