real magick cannot contradict nature, humans cannot create something from nothing [or in this case summon something fictional] so there is no spell that can bring a fictional character to life.
now, there are people who believe you could create a thoughtform, which is basically your energy focused to be like something. it's not real and it will go away once you stop feeding this energy, but some people do that. there's also some who theorize you could on the astral plane. but physically no, you cannot create anything physical from energy.
