I love Luffy! He is one of my favoriete characters, because he always has a smile on his face and he's naturally a funny guy. However, he is strong and always does his absolute best, especially when it involves his nakama, whom he would die for if he had to.
He has an amzing backstory, he is an amazing role model for friendship, he's strong, funny, almost always has a smile on his face, puts others before himself, and is the captain of the best crew and gathering of amzing characters of all time!!!
I love everything about him. His smile is adorable, his shadowed over eyes are badass, his personality is great, his sense of friendship is amazing and he is not afraid to cry in front of people (Marineford, Merry's end, Usopp's departure, Impel down, SA)
