JDG-00X Dark Gundam. On the eve of the 13th Gundam Fight, a brilliant scientist at the space colony of Neo Japan created a powerful new mobile fighter called the Ultimate Gundam. Thanks to the super science of nanotechnology, this massive machine has unlimited powers of self-enhancement, self-replication, and self-repair. However, the Ultimate Gundam was stolen and taken to Earth, where it transformed into the terrifying Dark Gundam - a mutating mechanical monster which now threatens to lay waste to the entire world.
