Mobile Suit Gundam U.C. 0094: Across The Sky

In Universal Century 0094, a live exercise for the MSN-001X Gundam Delta Kai is being carried out in outer space. This mobile suit is equipped the "NITRO System" that grants regular pilots the abilities of a Newtype. While the Gundam Delta Kai displays overwhelming power, a side-effect causes the test pilot's personality to become more aggressive.

Back on Earth, the Earth Federation Forces aggressor squadron "Raven Corps" arrives at the Federation Forces Mariana base. Brothers Braier and Ing Ryude, who are pilots stationed at Mariana base, participate in a mobile suit mock-combat exercise with the Raven corps. During the exercise, the brothers are attacked by the Raven corps using live ammunition. Piko Altidore, captain of the Raven corps, reveals the object of the attack is the Gundam Delta Kai stored in "Area X" of the Mariana base. During the battle, Ing boards the Gundam Delta Kai to defend the base against the Raven corps' assault. However, the NITRO system brings about a berserk state in Ing, causing him to attack both allies and enemies. Piko manages to subdue the Gundam Delta Kai with a pulse grenade and opens a communication line with Ing. After this exchange, Ing seemingly joins the Raven Corps and departs the Mariana base in the Gundam Delta Kai.
