YMMV / The Adventures of Cyclops and Phoenix

• Complete Monster: Askani World (Earth-4935) has En Sabah Nur and his equally evil daughter and topmost enforcer, Diamanda Nero:
  • Apocalypse is an incarnation of Earth-616 Apocalypse two thousand years in the future. His wickedness not dulled over two millennia, he has taken over much of North America and implemented his Social Darwinism beliefs. Perhaps his most vile crime was infecting an infant Nathan Summers, the future Cable, with a Techno-Organic virus two thousand years prior, just to have Nathan prove he was strong enough to eventually serve as Apocalypse's vessel, as the latter is burning through his bodies, and so has to take new ones more often. Even after finding out that Stryfe isn't the original Nathan but a clone, Apocalypse still tries to bodyjack the boy. Finally, Apocalypse is conducting research on a virus similar in composition to the Legacy Virus.
  • X-Men: Phoenix, by John Francis Moore et al. ^note takes place after Apocalypse has taken power, but several decades before the majority of the above story: High Councilor/High Prelate Diamanda Nero oversees Apocalypse's empire, decades before the majority of the above story, while the latter constructs his newest armor to house his body. A psychotic sadist who is introduced fatally, and gleefully, torturing a victim for information, Nero has killed many mutants, at which point she absorbs their powers. At one point, she tests a plague on an enclave, resulting in over 2,700 deaths. Using this knowledge, she creates Plague, basically a zombie turned into a Walking Wasteland. Her other crimes include more brutal torture and having her forces brutally kill a group assisting those fighting Apocalypse's rule.
