From obvious team-ups like Batman/Spider-Man and Batman/The Shadow to more unusual fare like Batman/Elmer Fudd, these are the best (as well as some of the weirdest) Batman crossovers of all time.

In the 1940 Technicolor joint A Wild Hare, hapless hunter Elmer Fudd goes on the prowl for rabbits but unfortunately sets his sights on Bugs Bunny, who's an agent of chaos rather than easy prey.
