Mobile Suit Gundam SEED (2002)

S01E21 Beyond the Clouds of Sand

The Lesseps and the Desert Dawn clash in battle. Kira and the Desert Tiger engage in combat, and both come to feel the weight of fighting a real person rather than an unseen foe. As the Strike's energy runs dangerously low, Kira is forced into a terrible choice: destroy Andrew's TMF/A-803 LaGOWE, or lose his own life.
