MONKEY D. LUFFY:
The lovable meat-loving rubber boy pirate. Despite not being able to swim, Luffy is actually pretty badass. With hellbent determination and love and trust in his friends, Luffy aims for the sky and strives for the title "King of the Pirates".
After eating a mysterious fruit, he gains rubber like abilities at the cost of being able to swim. He received the straw hat from a dear friend of his, Redhaired Shanks the pirate captain.
(fun fact: Luffy got the scar when he stabbed himself in the face to prove to Shanks how 'brave he was'.)
