Dao Stryver was a Gektl female Mandalorian warrior. Her period of activity occurred during the time of the Cold War. She facilitated Lema Xandret's journey, along with her followers, to Sebaddon. It was initially believed she vanished into a black hole during the Independent Operation Sebaddon, but after the operation concluded, she was discovered by Jet Nebula in a Tatooine cantina. Later in her life, she became a member of the Star Cabal.
She was considered one of the champions of Mandalore.
While the Star Cabal convened within the Star Chamber space station during the battle of Corellia, The Prince attempted to placate Kolovish and Yem Leksende regarding their defeat on Corellia by stating that Stryver was already collaborating with the Mandalorians.
Stryver's equipment included grey and green Mandalorian armor tailored to her large physique, a wrist-mounted flamethrower on her left arm, a Jetpack, a collapsible shock stave, a hand-held Disruptor pistol, a net launcher capable of firing interchangeable razornets and electronets, vibroblades, a concussion missile launcher, a restraining bolt launcher, Stun Darts, and a blaster rifle.
