(Nb. (1.) My lecture claim is that Superman and Captain Marvel, in Kingdom Come, are formed together as a duality that amounts to a Christ-type. (2.) "Orion" is a son of "Darkseid" from the Silver-Age classic New Gods.)
Have you seen Italian sculptor Adrian Tranquilli's series on Superheroes? I find it very interesting how he decided to depict them as vulnerable beings when they're so commonly known as 'super'. I've also noticed that Superman's body language is quite Jesus-like, similar to the visual representation in Kingdom Come you pointed out in lecture.
.... a few questions regarding religion in Kingdom Come:
I know Superman is a representation of Jesus, but is it possible that the four groups (the Justice League, Batman's new league, the Mankind Liberation Front, and the meta-humans) each represent a different religion? They all have very different views on how to do things, and Superman even uses the word "converts".
Connecting back to Hey Nostradamus! and the states of mind (heaven, purgatory, limbo, hell), is there something like this present in Kingdom Come too? When I first read it, I immediately associated Apokolips with hell, but started questioning myself when I realized how calm and seemingly understanding Orion is.
