Of course, the greatest hero of all time is Doctor Who. But since we are all talking about comic book superheroes here…

Captain America, hands down. Because he's a moral individualist and an anarchist.

I also like Professor X. I know he comes from a very privileged background, but I like his optimism.

I'm also a fan of Mark Ruffalo's Hulk.

The Amazing Spider-Man will always be my number one! I have loved him since I was very little, and will continue to love him until the day I did.

James T. Kirk, who taught me to confront this god nonsense.

This is actually a difficult question. When I get into a story/fictional world I rather create my own character to bring into the mentioned story/world, rather than relating to any of the cast.
Yet if we talk about charcters I can relate to... there are very few and most of them are either book or anime characters.

Growing up it was always about Batman and Spider-Man for me. I think mainly because I could realistically imagine myself becoming one of them. Even though extraordinarily unlikely, it's still possible I could become rich and have the resources to learn martial arts and detective skills and make or buy all sorts of crime fighting gadgets. Likewise I could still be bitten by a radioactive insect or other animal and have something happen to change me. And yes, sometimes I still fantasize about it...don't judge me.

The Flash is my favorite, because he’s just a good-hearted guy who became a superhero by accident. His story is never about justice or honor or duty. It’s about a guy who tries to save as many people as he can. Whenever he fails, it’s because HE wasn't fast enough.

Which is why it’s going to bother me when the DCEU fucks it up. They’re doing a Flashpoint movie just to reset the timeline and recast Batman. The story is about Flash running back in time to save his mother, which caused a ripple effect that altered major events. Superman became an underground government lab rat since childhood and Bruce Wayne was killed instead of his parents (you get the idea). The Flash has to fix the timeline before Earth is destroyed by a war between the Atlantans and The Amazons.

Captain America and the Hulk. The hulk will always have a very special spot in my heart because he helped me a lot growing up.

I related a lot to a nerd with body problems and anger issues who still managed to be a good guy. He really helped me feel less alone.

I'm currently though incredibly in love with captain america (not the current comic one, he's an asshole....) He symbolizes everything America SHOULD. True equality and justice. He isn't afraid to stand up to his leaders when they go a way he doesn't feel right about. He is able to still love his friends even when he feels they're making a mistake. He sees injustice and he fights, no matter if it's from foreign or domestic people. I was most certainly team cap during civil war, not because I couldn't see where tony was coming from, but because cap knows the government is still susceptible to corruption from hydra.

After that is black widow because 1) scarjo is bae. 2) she has such a deeply complex history and is a ruthless woman who will do whatever and whomever she needs to to get things done. She's tragic but she is stronger than anyone because of all she's gone through.

Oh and deadpool. Though he isn't so much a hero lol
