June 2015 is a big month for DC Comics, and with it comes a variant cover theme celebrating one of its very biggest villains -- the Joker.

CBR has the exclusive first look at five variant covers from the month: "Batgirl" #41 by Rafael Albuquerque; "The Flash" #41 by Eddy Barrows and Marcelo Maiolo; "Gotham Academy" #7 by Craig Rousseau; "Justice League" #41 by David Finch, Jonathan Glapion and Brad Anderson; and "Superman" #41 by Karl Kerschl.

DC has made variant themes a monthly tradition -- for the current month of March, it's DC superhero-infused movie poster homages. Here's a look at all of the Joker variants planned for June:
