I know the Rebellion is supposed to be based on <i>Paradise Lost</i> by John Milton, but I had a theory. The characters are based on Egyptian gods.
Madoka is Osiris,god of the afterlife.
Homura can be either Isis or Set. Moemura and "Badass" Homura are both Isis, Goddess of Magic and fertility, and Osiris' wife. Akuma Homura/Homucifer is Set/Seth, god of chaos, storms, and the desert, Osiris's once-loving brother, who betrayed, murdered, and usurped him.
Sayaka is Horus, god of the sky, war, and protection,and Osiris' son, who fought with Set.
Mami is both Ra, god of the sun and sworn enemy of Apep, and Hathor, goddess of motherhood and beauty.
Kyoko is Anubis, God of the dead and embalming.
Kyubey is Apep, God of evil and Entropy.
