Sadly probably a cheaper version than buying new....
I had somehow acquired three junker Twinfernos. I managed to build a complete one out of them, the second is waiting for inspiration and this is the third.
It has a Swoop titans head, wings from a junker TR Mindwipe, claws from an oversized KO of a Transformers Prime terrorcon, the forearms from a Siege Refraktor and the head from a Shadow Panther, with fangs added.
I made a little panel for the creature head to flip back and forth.
I hadn't given it a black wash at the time of photos.
