Isolde Siro was a purple-haired Human female fringe criminal.
Recruited into Lando's Commandos, Siro opposed the use of Air Marshal Von Asch in their mission to stop the TIE Pirates. In the ambush sprung by Captain Kine, Asch took a lightsaber bolt meant for Siro, who in turn killed Kine.
Asch survived the blast, and expressed his belief that Siro was to play an important role in the future.
