DC Versus Marvel Comics Crossover Limited Series Bundle Issues 1-4

When two entities known as the Brothers (the embodiments of both the Marvel and DC Multiverses) remembered each other's existence (due to recent cosmos-shaking events that tore the fabric of the Multiverses and redefined reality), they pitted combatants from their respective realities together. The winner would then destroy the loser (and its own respective Multiverse). To prevent this from happening, the Living Tribunal and the Spectre joined forces and combined the two universes together, creating the Amalgam universe. This universe had its own unique history, which was a combination of both Multiverses.

With the help of the hero named Access, the Living Tribunal and the Spectre managed to separate the two realities once more and the Amalgam Universe ceased to exist.

Full set, Issues 1-4.
