Yint was a weapons supplier for Liam Bilby of the Orion Syndicate. Members of his species bore ridges along the top of their heads, and in the middle of their faces.
In 2374, Yint sold Bilby three defective Klingon disruptors, claiming them to be in perfect working order. He was later killed by Bilby using the very same disruptors, after they had been repaired by Connelly, to prove a point about lying to the Syndicate. (DS9: "Honor Among Thieves")
Yint was played by actor Brad Blaisdell.
This character was only named in the source's end credits.
The prosthetics for Yint's species somewhat resemble the Tak Tak face, with the top and back of a Rotciv covering the rest of the head.
