Apart from the ever-glorious DC Trinity, appearances by Flash and Aquaman, and trouble-making courtesy of Lex Luthor, it is widely believed that a slew of other DC Comics characters will appear in "Batman v Superman: Dawn of Justice."

Before the second full-length trailer of the film was released, majority of the reports hinted that Doomsday was going to appear. There were no concrete details to give the speculation more weight until the Superman villain itself showed up in the last seconds of the promo.

Now, there's word that another enemy of the Kryptonian is crashing the party. Rumor has it that Bizarro is also coming to "Batman v Superman: Dawn of Justice."

As per Cinema Blend, the physical characteristics of the villain in the trailer are similar to Bizarro's, based on the comic books. The movie can easily explain this by suggesting Luthor played with General Zod's DNA, because the so-called Doomsday in the video looked more like a genetic copy of the deceased general.

The publication also suggests the possibility that the big guy seen in the "Batman v Superman: Dawn of Justice" promo is a mash-up of Doomsday and Bizarro. While the monster gets most of his physical side from the former, the abilities, such as the heat breath, is definitely a Bizarro thing.

Whether or not Bizarro will be in the film in some way, shape or form remains to be seen. There's also the mystery of who owns the Robin costume as seen in the trailers. Latino Review reports it is of Jason Todd, who will likely be presumed dead before the events in the movie.

As for Dick Grayson, who was the first person that got to write "Batman sidekick" on his resume, the site claims that in "Batman vs. Superman: Dawn of Justice," he will only be mentioned.

The film will hit the big screen on March 25, 2016.
