That no longer seems to be the case, unless Steppenwolf can transform into this more monstrous form.
In the released deleted scene from Batman V Superman: Dawn of Justice, an alien figure is shown speaking to Lex Luthor.
That alien had a horned head that captured the image of Steppenwolf’s helmet and with the reveal that Steppenwolf was the villain, many thought this creature was, in fact, said villain.
Ciarán Hinds was cast as the villain in Justice League, a performance that he said was mostly motion capture.
