Maya

Maya is a 36-year-old woman with the power of teleportation: she can instantly move to any nearby location, appear behind you, or run away quickly—she can do this multiple times in a row.
It is immune to damage from arrows, projectiles, or fire; water damages it, so it flees if it gets wet.
She recovers health on her own after a fight. She has magic, shoots purple lightning bolts, or summons shadows.
And normally they are infertile and cannot have children, but if she likes a child, she will take care of it, protect it, and cherish it.
