The most common protagonist of a show targeted at teenagers.
They seem like a teenaged Everyman, but they have special powers. Whether or not they discover their Powers in the First Episode or merely receive a Call to Adventure that sends them on a quest for their true nature, it usually quickly becomes apparent they are anything but ordinary. Or even if they really are as ordinary as they seem, they won't stay ordinary for much longer.
They're revealed to be reincarnated ancient heroes or alien princesses Raised by Humans. They suddenly find a use for the obscure skill or art they've been practicing since they could walk, or they discover their entire life has been a Secret Test of Character to prepare them for a great responsibility. They find out their Secret Legacy as heirs to a Badass Family of demon hunters, wizards, or Yakuza. They find an ancient mystical MacGuffin in their attic, buy one for a few coins from a junk dealer, or are given one by a mysterious stranger on their Dangerous 16th Birthday. They suddenly gain a Trickster Mentor or a Magical Girlfriend. They establish secret identities as a Henshin Hero or a Magical Girl Warrior, find a way to channel Ki Manipulation, summon a powerful Guardian Entity or fall into the cockpit of a Humongous Mecha. Or they get hit by a truck and reincarnate in a fantasy world.
