Some of you may remember I mentioned wanting to see a Transformer that turned into Wheelchair in TF: ROTF. Well I Found this on TFW2005.
"Revenge of the Fallen Illustrator Paul Ozzimo has updated his online portfolio with a selection of new concept images from Transformers Revenge of the Fallen. There is a detailed examination of the evolution of The Fallen's design and some alternate takes on the evil Decepticon's head, such as the cool Anubis / Decepticon symbol hybrid pictured to the left. There are also some concept sketches of Wheelie, the Kitchen Crew, and a couple of 'bots who did not make the cut - a very cool looking Submarine Robot, now updated with some new views, and a Wheelchair robot.
