Fan Casting The Prankster in Sort by Tropes

A person who loves practical jokes more than just a friend, and will not be selective about who they choose for a target - in fact, a success record with as many people on it as possible seems to be one of their life goals. They will be the constant annoyance of their friends, albeit humored and tolerated, akin to the Lovable Rogue. Using their tricks against the villain will usually be their Moment of Awesome that makes you forgive them for the rest.
