Pezun was an asteroid base at Lagrangian Point L4. It was established by the Principality of Zeon, but was occupied by the Earth Federation after the One Year War.


Pezun was an asteroid base constructed by the Principality of Zeon at Lagrangian Point L4, near Side 2 and Side 5.

Zeon used the base as a defensive location as well as to develop mobile suits. Pezun produced mobile suits for the Zeon war effort, in particular the MS-10 Pezun Dowadge that was named after it.


The Principality of Zeon used Pezun as one of three staging points during the One Year War. The asteroid was moved to guard Zeon’s flank during the war, with Solomon stationed at the other flank.

After the war, Pezun was occupied by the Earth Federation’s Mobile Suit Instructor’s Coprs under the Titans. When the Titans was disbanded by the Federation in UC 0088, the Instructor’s Corps seized Pezun in a military coup and declared themselves the New Desides.

The Federation sent the Task Force Alpha to quell the rebellion. The New Desides forces were pushed back and were forced to abandon the base on 12 March UC 0088. The rebels detonated nuclear warheads to destroy Pezun and damage the Federation fleet.
