It's a dinosaur wearing a gas mask and carrying air tanks. What more is there to say?
I first drew it for a t-shirt, but decided I should model it in Maya. I then sculpted it in ZBrush, but this is a lower res version using normal maps.
This model is for sale on Turbosquid as an OJB and FBX: turbosquid.com/3d-models/3d-dinosaur-gas-mask-model/419837 as well as a ZTL: turbosquid.com/3d-models/3ds-max-dinosaur-gas-mask/419858
Vote for him on Patch Together and maybe there will be a toy made of him one day: patchtogether.com/designs/designs/view/id/1398
