The Saci-Pererê is a Brazilian folklore about a one-legged man who lives in the forest, and loves to play tricks on people. He uses his cap* (autocorrect) to disappear and reappear elsewhere, sets animals loose, steals kid's toys, etc. Not scary but it's what came to mind.
Pretty sure you meant cap in place of cape, right? I'll say that does sound pretty badass though! Here's a Wikipedia link for folks who want to read more.
