While many of the important plot points remain lodged firmly in an average viewer’s mind, the smaller details can slip right under the radar. Even something as straightforward as heights and ages of recurring characters can become cloudy in a series as long as this one. Every once in a while, it does fans good to treat themselves to a bit of a refresher.

He aims to complete this lofty goal by hunting down the treasure left behind by the legendary pirate Gol D. Roger. To Luffy, becoming Pirate King represents ultimate freedom, as he believes the Pirate King would have the most freedom in the world.

• Height: 5' 11"

Roronoa Zoro is also known as "Pirate Hunter" Zoro. He's one of the Straw Hat Pirates' two main swordsmen, and was the first pirate besides Luffy himself to join the crew.

Originally a bounty hunter, Zoro seeks to become the greatest swordsman in the world. He dreams of this in order to one day honor a promise he made to his deceased childhood friend Kuina. So far in the series, he's doing excellent work at honing his craft.

8 "Cat Burglar" Nami

After Usopp helped the Straw Hats defeat the deadly Black Cat Pirates, Luffy gave him the opportunity to join the crew. Although some may describe Usopp as a bit of a coward, he hopes to eventually become a bold seafaring warrior like his father.

Chopper was once a normal reindeer before eating the Hito Hito no Mi, a Devil Fruit that allows for the transformation into human hybrid (or even a full human) at the consumer's will.

After his transformation, Chopper learned the basics of medicine from his parental figures, Doctors Hiriluk and Kureha. As part of Luffy's crew, Chopper's dream is to one day discover the cure to any and every disease. He travels the world in hopes of becoming such a doctor.

• Age: 30
• Birthday: February 6
• Height: 6' 2"

Nico "Devil Child" Robin (also known as the "Light of the Revolution") acts as the archaeologist of the Straw Hat Pirates, and was the sixth crewmember to join.

In addition, she is currently the only person alive with the ability to decipher Poneglyphs, a skill forbidden by the World Government.

Robin was initially opposed to the Straw Hat Pirates in her role as the vice president of Baroque Works, before eventually joining the crew. Her dream is to uncover the Rio Poneglyph.

A devastating incident later resulted in Franky being badly wounded, requiring his transformation into a cyborg.

Franky and his followers were initially opponents of the Straw Hats. However, circumstances later forced them to become allies. Once the antagonism waned, Frank saw Luffy's crew as an opportunity to fulfill his dream of creating a ship that could navigate the entire world. He constructed the Thousand Sunny, the second ship of the Straw Hat Pirates, and joined the crew to chase his dream.

2 "Soul King" Brook

• Age: 90
• Birthday: April 3
• Height: 8' 8.5"

"Soul King" Brook is the official musician of the Straw Hat Pirates. The eighth crewmember to join, Brook also serves as the second of the Straw Hats' swordsmen. Brook's powers originate from the Yomi Yomi no Mi, a Devil Fruit which gave him the ability to resurrect himself after death a single time. However, Brook learned to delve deeper into these powers, which granted him control over not only his own soul, but the souls of those around him.

Having originally served as a crewmember of the Rumbar Pirates, Brook had died and was resurrected. However, due the soul struggling to reach his abandoned body, time reduced his corpse to a mere skeleton, leaving only his iconic afro intact.

During this war, Jinbe befriended Luffy, and eventually allied with the Straw Hats to prevent a coup against the Ryugu Kingdom's Neptune Royal Family. In gratitude, Luffy invited him to join his crew . Jinbe's dream is to find a way to fulfill his former captain's dying wish of peace, coexistence, and understanding between humans and fish-men.
