* Percy Jackson: You might be referring to the *Percy Jackson & the Olympians* series by Rick Riordan. In this series, Percy is often accused of things he didn't do, but it's usually by monsters or people who misunderstand him. However, there isn't a specific instance where someone "framed" him in the way we might think of a criminal case.
* Other fictional characters: There might be other fictional characters named Percy who have been framed, but without more context, it's impossible to know.
* A real-life event: Perhaps you're thinking of a news story or a case where someone named Percy was framed.
To help me answer your question more accurately, please tell me:
* What context are you referring to? Is it a book, a movie, a real-life event, etc.?
* Who is Percy? Can you provide more details about this person?
Once you provide more information, I can help you figure out who framed Percy.
