The Captain Calaeno figure has a unique mold and stands on both thin legs with additional support from a cape. The figure is fitted with plenty of articulation points and comes with a translucent sword.
Storm King & Grubber are combined one a single plateau and fit more in the line of GoH Fan Series figures. Attached to the figures are strikes of magic/lightning and the Storm King is wielding a big staff. It's clear that this figure is not to be played with and is meant as a display piece.
