Given the vibe that my sona is female, it's sort of easy to see that my roster/cast is mostly female, and with a female persona also comes with a maternal personality. There are 3 chars of mine that fit the bill.

Mia Sevifet, my sona. Her maternal instincts come from protecting those she loves the most, whether she'd be macro to them.

Eris Falx. She is very maternal and protective and, despite all that chub, is built like a sumo wrestler, willing to strike down anyone who dares harm a hair on those she is protecting.

Setari. Her very personality is built around godlike love and care. She goes the extra mile to staunch harmful forces.
