Energon Ultra Magnus

Ultra Magnus is basically parts for Transformers Armada Optimus Prime. He transforms into a giant cannon for his back. He is actually quite bulky and nicely sized; definitely one of the better parts of the late Armada toyline. (This toy is actually a repaint from Energon; the original was painted Red and Black and given the name of some obscure Micromaster transport). He only appeared for something like 10 seconds in the Armada cartoon, which is too bad - I really liked the look of Optimus with those cannons on his back.
