Some weird Amalgam event happens, and the DC universe and the Doctor Who universe are merged.
Oa and Gallifrey go to war with one another.
- Fighting for Oa: The Guardians and the Green Lantern Corps, including their best Lanterns, like Hal Jordan and Kyle Rayner (without cosmic power-ups; they use the rings).
- Fighting for Gallifrey: The Time Lords, a fleet of War TARDISes, and the Doctor and the Master (neither of them switches sides or deserts).
No other parties may participate; everyone sits this out except the principles themselves.
Who takes it?
