Doomsday

As said, Zack Snyder may have built the Superman story arc in the DCEU as being a circular one, a battle between the good and the bad within a character. As mentioned previously, it all depends on perspective as far as Batman v Superman is concerned. However, Doomsday is a bit more special.

First of all, he clearly doesn't look (just yet) like the character from the comics, which can be explained, since his origin story wasn't kept. This version of the character is instead an amalgamation between the comic book Doomsday and Bizarro, a character which was also rumored to be in this movie (a rumor debunked, of course). This version of the character, for example, resembles the look from the comic book, but borrows Bizarro's origin story and some of the superpowers.

The thing that bothered most of the fans (besides the actual reveal) was the look of Doomsday "“ a combination between the LOTR cave troll, the new TNMT design, and the Incredible Hulk Abomination. Furthermore, there was an obvious lack of spikes.

But given what was said in the previous bullet, we do believe that Batman v Superman won't see the end of the baddie. Doomsday is known, in the comics at least, to come back to life and become immune to whatever previously killed him. This ability is also the one which transforms his body, adding more spikes every time.

So, what we believe is that he will die at the end of Batman v Superman. However, further down the line, we suspect that he will make an epic return, spikier than ever, only to die yet again, this time together with Superman. We do believe that, one way or another, the storyline that made him famous will be adapted on the big screens.
