Superhero

The superhero is conventionally in costume/disguise and works alone, such as Spider-Man who has no help at all from other people, a secret only he has and are the protagonist of the films. 

My character which is also the protagonist will be like Spider-Man in the fact that he will be doing everything on his own with no help from other people, as well as having no one else knowing his 'secret' which is a conventional aspect with superheroes as it keeps their true identity a secret and unknown.
