Doomsday could have looked a lot different in Batman v. Superman: Dawn of Justice. Early concept art for an initial design of the villain surfaced on social media from conceptual artist and creature designer Jerad S. Marantz.
Marantz, responsible for character designs in Batman v Superman and a host of other films for Warner Bros. and Marvel Studios shared a sketch of one of the early ideas for Doomsday's appearance. He described it as an "early design" and "one of my earliest passes."
The design is much closer to Doomsday's look in the comics with its bone spikes and protrusions on his back and shoulders, as well as his jaw. He even has what appears to be a halo around his neck similar to the Kryptonian armor Zod and his forces wore in Man of Steel. As detailed and threatening as it is, director Zack Snyder and Warner Bros. obviously went with something simpler.
Doomsday's visual look in Batman v Superman was decried by many fans who weren't pleased with the final product. There was also the problem of Doomsday's presence in the film feeling shoehorned in, adding to one more black mark on not only the movie's reputation but Zack Snyder's vision for the DC Extended Universe.
