(Agatha means Good and Beatrice means “she who brings beatitude”)
Annabelle has her eyebrows always burnt away due to her excessive use of a flamethrower and she’s basically a pyromaniac with a religious inspiration (so she burns the sinners). She is also afraid of the dark since she was a filly.
Beatrice is an albino and wears a mask with a suit which covers her entire body or the sunlight can burn her skin. She also experiences visions and weird omens.
Agatha is the older of the group and is the one which has seen so many stuff in her life and before deciding to become a nun she was quite a party-hard-gal in her youth. Now she is a bitter, life-hardened granny with a good aim, which keeps her sisters safe from the bad things life can throw at you.
Nunpone is probably inspired by such trope from anime, its quite obvious.
Mine are more inspired by the Sisters of Battle, while Beatrice is loosely based on King Baldwin from the movie Kingdom of Heaven and Fiver from watership Down
Edited
Sure feels that way.
