War of the Two Brothers

The War of the Two Brothers (also known as the DC and Marvel War) is an ongoing conflict between two godly brothers personifying the DC and Marvel universes. This conflict manifests itself as a series of battles between DC and Marvel characters.

History of the war
During the earlier stages of the war the Blue brother had a clear lead and the Red brother was losing.

In 2008 the Red brother devised a new strategy and began concentrated most of it's effort, energy, forces into a single universe (Earth 199,999 or the MCU). Instead of creating a new universe every few years and keeping the heroes separated into different dimensions the Red Brother started gathering up all the core Avengers to put into a single universe.

In 2012, when the Avengers united for the first time it was clear the gamble had paid off and the Blue Brother decided to try and copy this strategy, without fully understanding it.

Currently the Red brother retains a decisive advantage and every year Red adds more and more heroes to Earth 199,999 increasing it's defences.
