I cant really choose one, so I decided to put my top 5 choices... not necessarily in order
Naruto Uzumaki He's one of my all time favorite characters. He is determined to achieve his dream, and works hard to achieve it, reguardless of what others think.
Kakashi Hatake Not only is he a skilled shinobi, but he is an incredible mentor, and can always give a good laugh (to us...).
Natsu Dragneel He's incredibly powerful and loyal to his friends above all else. On top of that there's never a dull moment in Fairy Tail, and who wouldn't want friends like Natsu's.
Gray Fullbuster Behind Natsu and Erza, Gray is my favorite character in Fairy Tail. He's a talented wizard blessed with good looks and not lacking an ounce of wit.
Hikaru Hitachiin The twin brother of Kaoru Hitachiin and a member of the Ouran Highschool Host Club. He's a clueless troublemaker, but hes smarter than he looks.
