Helen Sham of Small Bricks Big World – 小積木 大世界 – has been building all sorts of Lego figures. Recently she has been building Batmans. Lots and lots of Batmans. There are at least eight of them, including normal Batman, Rainbow Batman, the Lego Movie Batman, and Fairy Batman. These figures are big, and seem to have a decent amount of motion. Helen has also offered them up for sale, which you can contact her for more details (here).
The best thing is that there are other big Lego figures. Including Robin and the Joker!
These Batman themed brickbuilt figures are all part of a greater series. Which includes Superman, Wonder Woman, Wolverine, Darth Vader, and the Beatles. You can find out a whole lot more information at Helen Sham’s Facebook page here: https://www.facebook.com/smallbricksbigworld/
