Charles Wallace Murray. Doesn't everyone want to have special powers, and play a significant role in making the world a better place?
Of course, Lafcadio (the lion who shot back) is also a strong choice. Unlike Lafcadio, however, I don't really care for marshmallows. I don't hate them, I just don't ever plan on taking a bath in them.
NOTE: I answered this quick, and reserve the right to change my answer a few million times. Today it's Charles Wallace, with Lafcadio in a close second.
