The best sidekick is Nightwing... He had the greatest mentor and father, Batman!

At last my avatar has a hero name and is Nightbird similar to nightwing 

nightwing rules!!

Well the best superheroes comes from DC universe. These are my favorites, like Nightwing, Sodam Yat, Batman Beyond and Tempest. But there are a few I like from Marvel Comics like Spiderman 2099 and Gambit. But those are not the only kind of heroes I consider the best. There is Terra and Riku from Kingdom Hearts that are two of the best heroes in that story.
