Did they ever get around to doing a Silik figure before the line was canceled? I think they did but I'm not sure....he might have just been a photo of an unproduced prototype I saw online.
Whether they did or not that line was woefully unappreciated in part because Trek toys have almost always been considered less cool and fun than Star Wars or other sci-fi/fantasy franchise figures and collectibles. I would have enjoyed seeing the line continue and add characters like Shran, Ambassador Soval, Admiral Forrest and even the Mirror Universe NX-01 officers.
