She could but in this AU the father is Adam who is also with Charlie and no, i'm not joking, the artist told in the comments. It seems like Charlie is angelsexual regardless of them being fallen or not, now i'm just waiting Emily and Lute to be drawed together with her, why Lute? Well there's a fanart of Lute x Vaggie made by the same person who did this which made me think about the possibility of these 5 being in some sort of relationship after batkingsalem leaked this info.
Batkingsalem is based, she(he?) ship not only popular ships like Chaggie but also others like Charlastor and GuitarPrincess, the later being their favorite Adam/Charlie related ship. Before you ask,no, Alastor don't make part of Charlie's little harem/polycule(?) by what i know.
when I posted these sketches I had no idea that the author had gone so far to imagine a pregnant Charlie for me it was like 90% of the fan art of that day where it was Charlie or Vaggie who became pregnant by magic or something like that since 90% of the time it's never justified
Nah, Adam is basically the very original case and supernatural equivalent of someone who in his younger days was athletic but gained a dad body after becoming a dad.
personally I would describe Adam physically as someone with a small stomach, not obese or morbidly obese, just overweight given what he eats, it's pretty much normal after all.
(afterward Adam is far from being small in my opinion he is between 2 m and 2 m 20 so to have a small stomach with this size he must weigh between 100kg and 135kg but these are only personal estimates nothing official)
I would say how but charlie can shapeshift so its not the same as husk and angel where the only explnation i can think of how that works is geen splicing.
Since Charlie is a shapeshifter, she could give herself a magic dick to help create babies.
"...dude, why not just general magical shenaniga-"
NO! MAGIC DICKS! TAKE IT OR LEAVE IT!
