A deleted scene from Batman V Superman: Dawn of Justice has been released via Warner Bros. YouTube account. Check it out below:
The scene features a demonic looking creature which could be one of Darkseid’s minons, Steppenwolf. He is surrounded by what looks like mother boxes, the same box we see in Silas Stone’s S.T.A.R. Labs video. This would explain how Lex Luthor knows that Darkseid is coming.
