Uterio War

The Uterio War was a large scale conflict that involved the entire Original Universe. It is also the 13th Arc of BZPB preceded by The Pandorica Opens and followed by The New World Order. It began when Uterio di Armechio convinced the Council of the Great Beings to declare war on the multiverse and strip the Users of their powers.

The universe divided itself into groups and planets that supported Uterio, were against his conquest, or were indifferent. Ultimately, most of those who were against him, such as the ZFT, Makuta Anima, Klak, D-Klak, Zev Raregroove, Osseron, Kakamu, K'theenya, and others formed a group known as the Rebel Alliance. Blackout worked with his mortal enemies to bring down a common foe in a historic conflict.

Trivia

 * The Uterio War was one of the largest conflicts (in scale) ever waged in BZPB history, second only to the war against Blackout (which is not even an official war). It involved countless galaxies, characters, and armies. The majority of the Users and their characters were involved in the war, at least in some minor way, shape, or form.
 * It is also the longest arc in BZPB history, as it lasted SEVERAL months and ended in 2012, IRL. Canon-wise, it lasted about a year. Sadly, several users complained about the length of the arc, despite its fan service and attempt at unification. This has made it one of the most controversial arcs as well.
 * Death toll: Unknown; possibly millions.
 * This is the only conflict that was its own arc.
