1.an anime about pirates living in a strange world and i mean very strange, story and drawn by Echiro Oda. the main character's name is Monkey D. Luffy and he wants to be king of the pirates in order to do so he, his crew and signature straw hat must find the legendary treasure of one piece. personally i love this anime it has a great balance of comedy and action. the plot is forever changing and the characters are extremely badass some of the most badass i've ever seen. you can always find a moving story behind each crew member and great laughs.

2. the anime 4-kids (curse them) screwed up causing a huge protest about owning the rights to te show , well we won and the rights belong to Funimation
one piece is an awesome anime

i hate 4-kids tv for what they did to one piece

A term used to describe a person who constantly wears an item of clothing which looks like it is two,being an under layer and top layer, but indeed they are attatched together, which is why it is called a one piece.
Andrei, stop wearing your one piece, you one piece.

the longest anime to ever be produced. it is also the most creative, meticulous, and diverse anime.

Monkey D. Luffy dreams to be the king of the pirates. to do so, he must adventure all over the globe, conquer the grand line, then find the one piece(the plot is quite complicated and includes immense amounts of world building; but it’s worth it)! He joins a directionally challenged swordsman, kleptomaniac navigator, pinocchio, Gordon Ramsey, a walking plushy, tortured genius/hottie, pansexual android, the poster child of hot topic, living sushi, and a furry’s free pass.

Seasons are categorized by adventure. Zoro is a true feminist. I might legit be into Robin. Their ship is a lamb then a lion, and everyone can get superpowers if they eat nasty fruit.

Fact: Truly the best anime of all time. Also government is evil, so it’s realistic.
Person 1: If I die before One Piece is finished, there was no reason for me being alive.

Person 2: Ye
