Well, in that case, you'll want a Greenbound Wendigo Avalancher to be combined with your Soulfused X Greenbound Zodar. X has to be an acquired template that makes its target eligible for Greenbound, or sets it up to be so. An idea's forming as to what we can do about that (incidentally, this idea actually makes this discussion on-topic), but I need an acquired template that can be applied to "any corporeal creature" or "any living corporeal creature" and type shifts it to something Greenbound or Wendigo can be applied to.
Wendigo is "animal, giant, humanoid, magical beast, or monstrous humanoid"
Please assume the type pyramid is being disregarded, though.
