I suspect another reason why not too many Evangelicals write superhero comics is that they’re often taught to be paranoid or at least cautious of characters like magic users, atheists and false teachers. There’s a reason why they can’t stand Harry Potter (to whatever degree) and even if Power Mark and Bible Man are superheroes, they don’t seem likely to willingly beat up people as often as Superman and Batman do. If the latter two are made by Jews, then Jews are drawn to self-empowerment and self-defence (in a way) as to avoid being heckled by Gentiles.
Christians either retreat or preach to chastise and if you will snark at people. Should Marvel’s Illyana Rasputina show up in Power Mark, she’d end up as a villainness. Same for DC’s Zatanna. Witches, even of the good variety, can’t be trusted or tolerated either way. No that there can’t be a good witch or wizard but if LOTR’s any indication, such a character like Gandalf only seems like a wizard because he’s supposed to be something like an angel. Or if there’s going to be a good wizard, they’ll end up as Dante’s Virgil.
Helpful but ultimately suspicious as Virgil’s not a Christian. There could never be a Thor because Christians are often taught to distrust pagan polytheism and see it as false either way. There could never be a Christian Stan Lee just as there could never be a Jewish Narnia. Such beliefs, though similar, can be incompatible. I’d say Christians are drawn to fantasy due to a chronic aloof malaise and paranoia about the world that they’d retreat real badly if preaching fails.
Jews are drawn to superheroes as to better their situation through very worldly things. Be it violence (at least in superhero media) or banking (as it had been condemned for Christians to do it). Jews go where Christians either ignore or abhor. The things that sometimes bother Christians are the things Jews willingly do for survival. So that’s my point about why Jews are drawn to superheroes.
It’s the need for self-empowerment for a really bad situation especially in the past. If Christians were in that position, they’d turn to God instead. That Christians are taught to thinking they’re weak and feeble should explain why superheroic self-empowerment and a desire to literally fight back doesn’t appeal to them (if I’m not mistaken Power Mark does forgive his sister).
If Power Mark’s any indication, it’s more appealing to be feeble yet on guard than to impulsively want to beat up your foes as in your typical superhero story.
