Rusot was a Cardassian Gul and an old friend of Legate Damar. Rusot served on Terok Nor when it was under Cardassian-Dominion control. Frustrated with the Dominion's occupation of Cardassia Prime, he joined Damar in planning the Cardassian Rebellion's initial attack on Rondac III, the Dominion's primary cloning facility. DS9: The Changing Face of Evil

As the rebellion gathered strength, Rusot served as Damar's second-in-command, although he greatly detested the need to accept assistance from Starfleet, and the presence of the Bajoran Kira Nerys as an advisor. He challenged Kira's recommendations at every turn, especially when Kira recommended that the resistance start attacking Cardassian-operated installations that had not joined the rebellion. DS9: When It Rains

Rusot was part of a small team, led by Damar, that launched a daring raid on the Kelvas repair facility, with the goal of hijacking a Jem'Hadar attack ship equipped with a Breen energy dampening weapon. When the plan started to fall apart, Rusot pulled a weapon on Kira and threatened to kill her, proposing that he and Damar take the weapon for themselves and use it to restore the old Cardassian Empire. Instead Damar killed Rusot, regretfully observing, "He was my friend. But his Cardassia is dead, and it won't be coming back." DS9: Tacking Into the Wind
