Dren served as Char Aznable's second-in-command during the initial assault on Side 7. He stayed with Char throughout the pursuit of the White Base to Earth. Following this, he continued serving under Char until Garma Zabi's death, which led to Char being reassigned to Zeon's forces at Belfast. Dren then returned to space to command the Camel Squadron. When the White Base came back to space to support the impending conflict, Char countered by enlisting the help of Dren's patrol squadron. In the ensuing battle, the RX-78 Gundam struck Dren's Musai with its beam saber, tearing a massive hole in the hull. This caused Dren to be sucked into the vacuum of space, resulting in his death.
