Martia the Shape-Shifter
Playmates going back to the earlier Trek films led to some bizarre moments, like this figure of the Rura Penthe con Martia, who was arguably best known for shapeshifting to Kirk to double cross him to the Klingons, and then being killed after actual Kirk managed to dupe the Klingons into believing that he was Martia in disguise. At that point, why not just buy a second Kirk figure?
