Titans (Gundam) was an elite unit of the Earth Federation Forces established in UC 0083 after the conclusion of Operation Stardust. Their original intention was to defend the Earth Federation against supporters of the Principality of Zeon, as well as to investigate Zeon sympathizers. However, they eventually turned rogue, allying themselves with Axis Zeon in order to fight against the AEUG in an attempt to gain control over the Earth Sphere. They were all but wiped out by the AEUG at the end of the Gryps Conflict in UC 0088.
Some of the surviving members of the Titans watch in horror that the Titans are finished and some of them formed their own group while some of them join Axis.
