Bleeding Cool is reporting that concept art exists for Batman v Superman: Dawn of Justice featuring the character Doomsday, whose primary claim to fame is beating the crap out of Superman so hard that Superman died. The 90's were like that.
And, you know, at this point why not? The film already features Batman, Superman, Lex Luthor, Wonder Woman, Cyborg, Lois Lane, Alfred, Perry White, and is rumored to be including hints of Arrow, Aquaman, Green Lantern, The Flash, and others. Surely the addition of Doomsday will be the thing that finally excites us? We hope Paul Giamatti is playing him. His Rhino was effortless and beautiful.
