Butt-Monkey

Sometimes, a character has the only purpose to be abused by the rest of the cast of the media they come from, no matter how contrived the setup is. A character like this is known as a "Megward the Wizard".

The trope's name itself is a pun of the names of three characters that were some of the first characters to be part of the trope itself. These characters are Squidward Tentacles, Meg Griffin and Kyle the Wizard.

Description
A "Megward the Wizard" is a character that is written, either intentionally or not, under the purpose to be commonly abused by the rest or most of the rest of the character cast from the piece of media they come from, no matter how contrived the setup is or what reason the character might get abused. The types of abuse the characters might receive have no limits whatsoever; they can vary from mistreatment, being poked fun at and bullied to getting injured severely, or even kidnapped and murdered.

When there are multiple "Megward the Wizards" in a piece of media, these characters are generally written to be allies or friends, and it is rare for a "Megward the Wizard" to be enemies with another one.
