The blade of the pick does have a bull-skull feel to it. They could have found a way to incorporate that as the helmet.
But overall I'm pleasantly surprised with this guy. The head's a much brighter white than the packaging shows, and the alt-mode works 10X better in this colour-scheme than it did with Darkmount.
Now cough up a Submarauder for me, and I'll be a happy camper.
