It is an open secret that cartoon character creators usually give the characters features of real human beings. There are cases whereby even character traits and features are taken to the screen. Later on, it became a question for us as to whether cartoon characters really exist or not, whether they are just figment of imagination or they are real human beings living with us.
The case is there are some times whereby cartoon characters are actually real human beings existing with us in the world, and also in some other cases, they are just figments of the imagination of the cartoon animation movie creator.
Some of the cases where the cartoon characters really do exist include that of Montgomery Burns from the cartoon movie the Simpsons, he was found to actually exist in real life with his real name to be Baron Jacob. Also, most of the characters in Naruto are real.
