Shield and warhammer set. Pose #1: hammer and shield together, one in each hand. Pose #2: Hammer only (default left hand). Pose #3: hammer only, (default right hand). Pose #4: shield only (default left hand).
Shield: shaped approximately like an inverted triangle, the flat top being the bull's forehead and the bottom being the bull's nose. Facial features appear on the shield in bas relief, prominant eyes and eyebrows. Angry face. Horns point forward like spikes and a nostril ring dangles from the bull's nose at the bottom of the shield. Colour dark metal like iron. Possibly set eyes with red or green gemstones and matching haze from the nostrils like hot or toxic breath. :)
Warhammer: two headed warhammer topped with a spike. Head shapes are square and the handle is solid and fairly short. Nothing dainty or delicate here. :p. Bull shaped relief images on heads of hammer, possibly tribal style. Rough sketch to come.

First pose: an innocent looking formal tophat, this can be in any color or the typical black
Second pose: Tophat flattens down into an oversized ninja type throwing star.
Third pose: The blades can pop out and become hand held. Though the handles wouldn't be as large or bulky
