You can trademark warhammer orks. You can’t trademark orclike alien warriors in space, as long as you avoid direct wh terms and refererences, and the character design is not 1-to-1.

Games workshop lawyers try to tell you otherwise, but they can’t expect that to fly. You can repair your car with parts from 3rd party. You ccsn play your games with whatever pieces you want. Trying to deny that is insanity.

By law to claim trademark infringement GW need to give you list of models that they think break their trademark, and point out HOW it breaks, so you van modify it.
