Here's one better:
Twins, but one's a guy and one's a girl. They guy would inherit the whip and be essentially a warrior type character. Essentially, he'd be your typical Belmont vampire hunter. His twin sister would be a master of unarmed combat but would also have strong magical abilities centered around fire, ice, and lightning which she would use to augment her attacks as well as defense. For example, cloaking herself in fire to fire damage to enemies who get too close. She would also be able to cast projectile spells like Sypha Belnades.
