A civil war between Nintendo and Fantendo broke out after an argument over who owned more land in the gaming universe. The Nintendo armies were commanded by Mario and his friends and enemies and they were to defeat Fantendo. They fought against each other so much that it got serious and led to a universal war. This distracted everyone so much that Dimentio took over the whole universe. He created minions to kill all of the armies so he would rule all universes. But the armies kept fighting.
