By 2361, the Obsidian Order had discovered that Danar bore a resemblance to several Humans, Klingons and Romulans and considered him as a candidate to be surgically altered for Order missions. Danar always refused, but Corbin Entek considered that Danar would have lacked the subtlety required for Order operations anyway. (DS9 novel: Fearful Symmetry)
- This may have been a tip of the hat to the actor who played Danar, Vaughn Armstrong, who had also played various Humans, Klingons, Romulans and other roles in many Star Trek episodes.
In 2369, Danar and his ship pursued the Bajoran Tahna Los, who had killed many Cardassians and had also stolen a antimatter converter, into the Bajor system and to Deep Space 9. Danar attempted to pursuade Benjamin Sisko to turn Tahna over to him, although Sisko refused. Danar later took the Aldara back into Cardassian space. Sisko later contacted Danar to ask if his ship was in range of the hijacked USS Yangtzee Kiang, which was carrying a bilitrium explosive device. The Aldara was not, although Danar began to tell Sisko he had warned him about Tahna, before Sisko ended the connection. (DS9 episode: "Past Prologue"; WizKids module: Attack Wing)
After the incident with Tahna Los, Danar was reported by Doctor Julian Bashir as a typical xenophobic member of the Cardassian military. Klingon Imperial Intelligence has noted that he was served with distinction during the Klingon-Cardassian War and it is also known that he was a strong supporter of Cardassia's alliance with the Dominion. Despite his xenophobia, he is known to have worked well with the Jem'Hadar and during the Dominion War it was believed he was assigned to one of the reactivated Tonga class blockade runners.
