The Great War

The Great War is a major conflict in Earth-X199999 that erupted after the death of the majority of the members of the Cosmic Avengers at the hands of the mad Titan, Thanos.

The war began as a two-way battle between the Shield, an alliance among various superhero organizations across the universe, and the Horde, a group of villains who aligned themselves with Thanos and his cause.
