United Abomination is a mistake, a cancer in the multiverse that was never meant to exist.

It is the culmination of hundreds or even thousands of Countryhuman AUs smashing and merging with each other resulting in a disgusting abomination and the reason for this event happening is yet to be known.

While United Abomination can shapeshift it most often wears the face of the UN flag although more broken and all the once separated minds have combined into one corrupted and malevolent hive mind.
