Ari

Ari was a Cardassian male in the 24th Century who enlisted in the Cardassian Guard and served as a foot soldier and personal assistant for Legate Tekeny Ghemor. While in service, he idolised Ghemor and considered him to be a great man for risking everything his position had granted him for the Cardassian dissident movement. Ari proceeded to join the movement. Ghemor, fearing his daughter Iliana (really Kira Nerys) would be taken away by Obsidian Order agents, arranged for Ari to get Kira to safety. However, Corbin Entek and two other Obsidian agents arrived and Ari was shot by Entek and killed.
