Kidou Senshi Gundam 00

Synopsis

The three superpowers agree to form a combined military force under UN command to eliminate Celestial Being. The 30 GN Drives found in Antarctica are installed in new GN-X mobile suits, with each of the superpowers getting ten apiece. Meanwhile, Kinue encounters Ali Al-Saachez, who kills her for digging too deep about his involvement with the Gundams. Wang Liu Mei throws her support behind the Trinity siblings and Sumeragi tells Ian to retrieve the GN Arms. The Thrones attack a HRL military installation, but are forced to retreat when they are overwhelmed by the HRL's new GN-X squadron. In the meantime, Alejandro reveals his plan to overthrow Celestial Being, with Veda being his main obstacle. Landing in a secret facility on the moon, he and Ribbons gain access to the room containing Veda's main supercomputer core.
