What figure of speech is this...? Please help!!?

I have sentence that uses a writing technique, such as a simile, metaphor, idom etc.... and i cannot think of the term for this example. The exampe is " did not mean to frighten you, Sleeping Beauty. I know the definition of the term is when you compare a person or thing to a made up or fictional character, such as, You lie like Pinnicho or your my Cinderella. If you could please provide me with what figure of speech that is, it would be greatly appriciated.
