A golem horse, built out of droid parts in the same way as I made this.
Its head is completely vestigial, and it's supposed to see out of the eye in its chest, where there's also a pair of mandibles. The Horse Golem is a powerful steed to ride into battle.
This in essence is a possible prototype for a bionicle MOC. I've done it before here, and it worked quite well. I've also made a couple of minifig bionicles, which I might use for dioramas or something ^^ I'm going to build Korrothis - I need my characters not to be 1 1/2 feet tall.
Oh, by the way. This theme. John, if you're looking at this, Too Human seems like THE game for you, know what I mean? Almost all fo your characters would fit into that game perfectly ^^
