This figure was actually give away as a prize on the Realm of Collectors' "Breaking the Mold" podcast on an episode where they had me on as a guest. The amazing hosts bought this piece from me to give away to one of their listeners. You can check out that podcast here.
This started with a Deltigar the Destroyer figure. I replaced the normal bare chest and arm with ones from a Bromden Ironjaw and painted the green to match the rest of the body. His extra head was a MOTU Classic Fisto cast that I painted and his cape is from a Spawn Viking Age Skullsplitter figure.
