The Uncanny X-Men 1981 #534 - back issue - $6.00

Cyclops breaks Utopia's self-imposed quarantine and leads other flu-stricken mutants to reinforce Angel's team in a battle against normal humans with X-Men powers. In addition to developing the addictive, power-granting drug, Lobe's Sublime Corporation is also responsible for the HX-N1 influenza that only strikes mutants. Elsewhere, Emma Frost and Sebastian Shaw finally fight it out.

Normal Osborn tortured children to discover the extent of their new-found abilities. The Avengers bring together six of these kids to train, but the teachers have a secret that they must keep from their very powerful students.
