Superman (Clark Kent), in the sense that I believe no matter what you have to try your best to help others, even if all I'm capable of giving is a smile to a stranger I have this thought process in my head that I have no idea what another person is going through, a simple smile may be the one good thing they have that day and if I'm capable of giving that then I must.
I would also say Star-Lord (Peter quill) as music is my life, I love obscure songs, I love having a soundtrack to my life, I love living in song
