Badass Digest is dumping some big potential spoilers about the upcoming Batman v Superman: dawn of Justice’s bad guys.

According to the Badass Digest, an old Batman villain will be making an appearance. Check out the news below:

From Badass Digest:

Hardcore fans will recognize that as the name of the KGBeast, a Batman villain introduced in 1988’s classic Ten Nights of the Beast storyline. In that story the Beast, an enhanced agent of the KGB, came to the US to kill ten targets, and he did it with extreme measures, including poisoning an entire 200 person dinner party to get one guy. He battled Batman to a standstill, and at one point when entangled in the Batrope the KGBeast cut off his own hand to escape. He of course put a cybernetic gun on the stump, as you do.

Faraci goes on to say that we won’t be seeing this version of KHBeast in BvS, but his name appears in the screenplay, so listen closely!

The report also confirms that we’ll be seeing Doomsday as the big bad for the film and… that while Joker isn’t in the film, he’s mentioned and Superman is aware of him.

Batman v Superman: Dawn of Justice hits theatres March 25, 2016.
