Susie McCallister is the head counselor and the main antagonist.
Susie is a witch and therefore can manipulate magic, either by herself or by using her wand. In the opening theme song she is seen using telekinesis to lift chips into her mouth, she has also been seen teleporting, elongating her body parts, reversing time, freezing things, changing the time of day, making clones, transforming into creatures, flying (through the use of a broomstick), protective bubbles and instantly changing her clothes.
In the series, Susie is shown as an arrogant, short-tempered, bossy character. Susie likes tormenting the campers in her charge, becoming upset when things don't go her way. She takes great enjoyment in taunting her campers, specifically Oscar, and, on a lesser extent, Hedgehog.(i.e.: Hedgehog Werewolf, punishing the whole camp to make Hedgehog suffer)
She is shown to hate being asked personal questions where she started to yell Pepper for 20 minutes after he asked how her day was. However, she is somewhat sensitive to her friends, albeit in a somewhat cruel way. (i.e.: in Ghost the Boy, where it's implied she erased Ghost the Boy's memories to keep him and Betsy apart).
