Batman Vs. Superman Merchandise References Joker & Robin Costume
We also see what looks to be a Joker car with the packing reading: "Guthams Dark Protector." Batman's horns are circled (or it's a halo), Gotham City Police Department is crossed out, and "HERO" is written over Batman, with the Bat symbol behind the vehicle.
We see the writing on the Joker packaging is similar to the Robin costume from the Batman Vs. Supreman trailer (pictured above), which seemingly confirms Joker's involvement one way or another.
"Batman v Superman: Dawn of Justice" has a March 25, 2016 release starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter as Senator Finch and Tao Okamoto as Mercy Graves. Justice League is to follow directed by Zack Snyder as well.
Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
