After researching more into the false hero through Propps character theory, I discovered that what I understood about the false hero at the beginning being the role who is behind the scenes and is not witnessed until later on in the narrative. Changed after I looked int the false hero's functions, described as the role that appears in the disappearance of the hero and tries to claim that he is the hero with reasoning.
One example that shows a false hero is from The Princess and The Frog, where the main male hero has been turned into a frog and someone else disguises himself as him, almost stealing his identity. This changed the way I viewed my whole argument of a character being behind the scenes and helping the character out.
Although this is ok, as I now have a new argument for a character that focuses on having different roles within a narrative and how this type of character can have advantages and disadvantages from role switching. Also how the changes in roles effects the viewer's perception of the character.
