Magical Cracker

The respective counterpoint to the Magical Negro. A white character in TV or Film Media that solves all the problems of the people around them, using an unreasonably broad range of suspiciously advanced skills or just straight up magic. They are usually female, guardian-type characters with kind demeanours whom also present the constant low-level threat they might put you inside their handbag-porthole if you cross them - never to be seen again.
