Thor by J. Michael Straczynski Vol. 3 TP

Some moments define a god. Some define evil. Some define both. Mjolnir lies shattered, the blood of a god splattered upon the many shards strewn around Thor's feet. With his half-brother in exile and without the power of his greatest weapon, Loki's gambit has come down to this: merging the fate of Asgard with Doctor Doom's Latveria. The master plan in the making for two years culminates in the defining moments of two of Marvel's most vile villains, as Loki and Doom unite for an act of unspeakable evil you'll have to see to believe!
