📘 Series Summary
Following the success of the 1994 limited series, Further Adventures of Cyclops and Phoenix takes Scott Summers and Jean Grey on another journey through time—this time to Victorian London in 1859. Written by Peter Milligan with moody, atmospheric art by John Paul Leon and inks by Klaus Janson, this series serves as the definitive origin story for one of the X-Men’s greatest foes: Mr. Sinister.
The narrative explores the life of Nathaniel Essex, a scientist obsessed with Darwinian evolution and the "Essex Factors" (mutations). When Essex encounters the ancient mutant Apocalypse, he is transformed into a pale, immortal engine of genetic manipulation. Cyclops and Phoenix must navigate the rigid social structures of the 19th century and attempt to prevent the birth of Sinister, only to realize their presence in the past is inextricably linked to his creation.
