Probably parenthood. Family, or lack thereof. Finding salvation in giving life in place of one you lost

Noir Fiction. Every single character.

It's what put the "Noir" in Noir-Mobius, after all.

(yes I sent my own question to mysself)

For me personally, I tend to accidentally make a lot of my oc's motifs and themes focus around consequences. A lot of my characters stories are about them dealing with the aftermath of their decisions or actions on life, and it is entirely unintentional.

Another, as was pointed out by a friend, is that a lot of them also tend to revolver around prosthetics or cybernetics, a lot of them have some form of one or the other, whether it be a prosthetic arm, cybernetic enhancements, etc.
