Exiled #1

This 2012 one-shot kicks off the five-part crossover uniting Marvel's Journey Into Mystery and New Mutants, with writers Kieron Gillen, Dan Abnett, and Andy Lanning promising that "Thor & Loki's past collides with the New Mutants' future!" Stephanie Hans's cover delivers on that tension beautifully — a winged-helmeted Thor raises Mjolnir center stage while several New Mutants, including a figure blazing with fiery energy, fan out beside him against a bridge's iron framework, with a sword-wielding dark figure looming on the left. It's a confident, atmospheric opening image for what looks to be a genuinely compelling team-up between Asgardian mythology and mutant drama.
