The Übermensch Union is a shadowy underground organization in Area D that seeks to cause disorder and chaos among the altereds and gain influence over the East, West, and South territories controlled by Kidou, Asura, and Gozu.
They use tactics such as taking hostages and manipulating the groups to face each other.
Übermensch Union's hierarchy is unclear whenever there are smaller groups or every member is on his own. It appears that only Owl's Eye and Jin Kazaragi knows who is the real leader.
