The X-Men #106

Dark Shroud of the Past!" arrives in this 1977 Marvel issue, with Dave Cockrum's cover depicting a dramatic mid-air clash: a large figure in a dark costume — Angel — lunging forward firing optic blasts, while Storm, Colossus, Banshee, and other members of the All-New, All-Different X-Men are scattered and reeling from the assault. The cover copy warns that Angel has come to murder his former teammates using their own leader's deadly eye blasts, promising a tense, hero-vs-hero confrontation. With Chris Claremont and Mantlo on the script and Cockrum's kinetic linework setting the stage, this issue delivers the kind of charged, unpredictable energy that made the relaunched X-Men series so compelling in its era.
