Marvel Legacy hits Asgard with a bang, with... the death of the Mighty Thor! The final judgment comes as the Mangog arrives. The War Thor will meet the beast head-on, but even the bloodthirst of this Ultimate hammer-wielder may pale in comparison to the Mangog's might! The battle rages even as Jane Foster's cancer takes a turn for the worse, and she might not have to wait for the final judgment at all. The clock is ticking, the War of the Realms is spreading, and Mjolnir cannot save her this time. Can even the legendary Hercules help avert disaster? It's the beginning of the end - one that will lead to the most dramatic return in the Marvel Universe!
