Because it's Captain Sisko. Gul Dukat is neat, but damnit, I think Sisko's the most awesome Captain in Starfleet. You don't f- with the Sisko or he will f- you right up. And now he's in minimate form, one of my favorite toy forms ever.
There's actually a variant of this sisko, Commaner Sisko. But they gave him button eyes so he looks like a mix between Sisko & an animal from Bambi. It's kinda disconcerting. Plus Commander Sisko wasn't as awesome as Captain Sisko, who, as stated previous, would f- your sh- up if he felt it was the right thing to do.
Besides, this completes my line of "Awesome Star Trek Captains in minimate form."
They've already made Pike, who is pretty much only memorable as being the guy Kirk replaced and sitting in that box while beeping once for yes. And I don't give a damn if they never make a Janeway. Does anyone? Oh right, and Scott Bacula.
