The trailers for the film feature different variants of the Bat Suit. One of these variants is labeled "2011 Comic-Con Exclusive". This suit is a mini-figure that was given out in raffles at New York Comic-Con and San Diego Comic-Con in 2011 to coincide with Lego re-launching the Superheroes theme. The mini-figure is based off of Christian Bale's suit from The Dark Knight and The Dark Knight Rises. Another recognizable suit that's visible is Terry McGinnis's suit from the animated cartoon Batman Beyond.
The film will include appearances not only Batman's "rogues gallery" of recognizable villains, but also many lesser-known faces like Orca, Dr. Phosphorus, and the Mutant Leader from The Dark Knight Returns. Also visible in trailers are some of the most obscure and campy enemies Batman has ever faced, including The Eraser (a pencil-themed villain) The Polka Dot Man, Crazy Quilt, Kite Man and King Tut, a pharaoh villain from the 1966 Batman TV series.
