Bud Compson's power stare is an unsettling glare that can make a person flee, or be hypnotized. Seeing it through sunglasses can weaken its effect. Bud had developed the ability through staring contests with his older siblings.
Bud first used it in "Based on a True Story" to scare away the Tibble Twins for throwing snowballs at his and D.W.'s snowman. He later tried using it in "Read and Flumberghast" to make Tommy Tibble confess, but Tommy put on sunglasses and was able to resist.
