The Mighty Thor #18

This 2012 milestone issue marks the prologue to "Everything Burns," with Alan Davis and Mark Farmer delivering a cover that crackles with energy — Thor charges forward, Mjolnir raised high and lightning blazing behind him, while a young Loki rushes at his side against a fiery red backdrop. The pairing of the God of Thunder and his complicated younger companion hints at the high-stakes Asgardian drama within, written by Matt Fraction and Kieron Gillen. Published during Thor's 50th anniversary (1962–2012), it's a fitting entry point for one of Marvel's most compelling cosmic sagas.
