Who is the best guardian character in anime?

[DarkAngel]

it can be from the antagonist side or the people just fighting on the wrong side.
do you have any character for this list!

 

[Rinko]

Most of the characters in Naruto.
Characters in One piece too. The best guardian character would probably be Code geass's protagonist

 

[Rika]

The best guardian character is someone who would charge forward even after knowing the bleak outcome like Jirayiya, Itachi, Minato and other characters. They are like silent guardians protecting others without hoping for anything in return.
