Re: Darkseid is the Villain in Justice League
Perhaps we need to approach Darkseid in reverse.
Darkseid has two sons; and if either appear in the JL film, they will be played by men in costumes. Darkseid, like his sons, was once fleshy and human in appearance. The Omega Force made him look monsterous, but it did not change him into a nine foot tall special effect.
Doomsday is a massive special effects creature. Darkseid is not.
