All you have to decide is what to do with the time that is given to you
While this guy isn't necessarily a hero (in that he is a protagonist), Gandalf still deserves to be mentioned. He is the classic archetype not only for mystical and mysterious old characters, but also as an archetype that serves as the mentor to the main character, much like Obi-Wan Kenobi or Dumbledore. However, the only difference is that those two characters died, but were still able to guide the main character from beyond the grave. Unlike those two farts, who died and stayed dead, he died but came back twice as awesome as before. And he would go on to put Saruman in his place merely by saying "Your staff is broken" which is essentially the same as looking him in the eye and saying "F%^& you! You think you're awesome? I fought a huge ass demon". If you don't know what I am talking about, you either haven't read the books or seen the extended versions of the movies. Please remedy this as soon as humanely possible... Seriously, I'm not kidding. You will become a better person by seeing these movies. Jesus wants you to see these movies. Are you going to let down Jesus? On the month of his birthday? Dude, you are cruel!
