So I had an RP with a friend where Meta Knight found an extremely powerful weapon called the Coup Parfait, and decided to tame it so he could guard it from evil. However, it only reacted to signs of its old owner, who was very girly. So Meta Knight had himself transformed physically and started acting mentally as girly as possible so he could claim ownership, put it in storage, and go back to normal. However, it turns out the sword actually powers itself off of girliness and locks its owner into being as girly as possible so its power never falters. As a result, while Meta Knight has her mind fairly intact, her body is stuck that way and his mind is compelled to do and enjoy girly things.

Before you ask, I don't have a log of the RP anymore.
