Star Trek Select range of action figures, Mr Worf.
On display was a prototype, which demonstrated how the new Worf will, as is typical of figures in the range, be part sculptural, and part poseable, and feature a range of interchangeable parts to allow you to display as desired. As well as a base, the Worf figure will come with an assortment of weapons, and different, suitably posed, arms to hold them, plus interchangeable hair!
TrekMovie and Toy News International were there to take photos, and you can see many more in their respective galleries, in addition to the ones I've picked out here.
Worf will be the fourth Star Trek Select figure, following the already released Captain Picard, and first TOS pairing, Kirk (with Khan) and Spock (with the Horta). There's some time to wait yet though, as DST aren't expecting Worf to materialise until winter 2015.
