When an anime fan watches a juggernaut shonen anime series like One Piece, they must focus on the overall plot and the most important details of the characters such as their Devil Fruits or their personal motives. There's a lot to keep track of across 1,000+ episodes and almost as many characters, but on a second pass, a One Piece fan can pick up on small details they missed the first time.
Spotting fun little details for One Piece's heroes and villains alike can make them feel deeper and better-rounded, and it's even better when fans add personal statistics like height and birthdays in the mix. All that cam greatly humanize a character, even the villains, and a villain's birthday will also show fans what their zodaic signs are. Some One Piece antagonists fit their signs well, and others totally contradict their astrological signs.
10 Sir Crocodile
Sir Crocodile was protagonist Monkey D. Luffy's first major villain in the Grand Line, being the mastermind behind the civil war and chaos in the Alabasta Kingdom. Crocodile could also fight his fights in person, defeating Luffy in two duels before finally losing to Luffy in their bitter round 3 battle.
Sir Crocodile, like many One Piece male characters, is a tall fellow with an imposing height, though he's shorter than most other iconic villains in the series. Crocodile is 253 centimeters tall, and his birthday is September 5th. That means he's a Virgo, an earth sign known for its hardworking, analytical, and independent nature.
9 Donquixote Doflamingo
When Luffy arrived in the New World, he heard of the mighty warlord Donquixote Doflamingo, who ruled the island Dressrosa with an iron fist. After an adventure on Punk Hazard, Luffy arrived on Dressrosa to face the mighty Doflamingo and his String-String Fruit in person, a battle that saw Luffy's first use of Gear 4.
Doflamingo, like many One Piece antagonists, is a tall and imposing person at 305 centimeters, and he marks his birthday on October 23rd. This means Doflamingo is a Scorpio, a water sign known for diving deep into a challenge or a mystery with cunning and sharp insights, which fits a ruler like Doflamingo.
8 Arlong
Arlong was the final and strongest One Piece villain whom Luffy properly fought in the East Blue saga. Arlong captured Nami's home village and demanded tribute from its inhabitants, and when Arlong refused to sell the village to Nami years later, it was up to Luffy to save the day.
Arlong is a moderately tall One Piece villain, a burly fish-man standing at 263 cm in height. He was born on May 3rd, so he was born under the sign Taurus, an earth sign known for its bull-like stubbornness and reliability. Taurus also represents a love of earthly comforts like baths, as Arlong's luxurious Arlong Park resort would suggest.
7 Rob Lucci
Rob Lucci served as the main antagonist of the Water 7 saga, though he wasn't alone – he had plenty of help from his fellow CP9 members like Kalifa, Blueno, and Kaku as well, making it a fair fight against the numerous Straw Hat Pirates and Franky's own crew. Rob is also one of One Piece's most formidable Zoan-type Devil Fruit users.
Rob Lucci is one of the shorter One Piece villains at 212 centimeters, though he's still much taller than most anime men. His birthday is June 2nd, so his zodiac sign is Gemini. That air sign, represented by twins, is all about having a whimsical, fast-moving imagination and pursuing many projects, but Rob Lucci is more like the opposite.
6 Captain Blackbeard
Marshall D. Teach, or Captain Blackbeard, has slowly but surely risen to prominence as one of One Piece's most powerful and consequential villains of all. He doubled his firepower when he somehow stole Whitebeard's Devil Fruit, and now he leads an entire pirate armada as one of the Four Emperors.
Captain Blackbeard is a tall character even by One Piece standards at 334 centimeters, making him one of the tallest human characters. He was born on August 3rd, making him a Leo. This fire sign, represented by a lion, is all about pride and reveling in the spotlight, which suits Blackbeard's flamboyant antics well.
5 Enel
Enel was the primary antagonist of the Sky island saga, which had a distinct isekai feel to it. Enel had become the Sky Island's tyrannical ruler, a lightning "god" who inhabited the Upper Yard, and he even used Color of Observation Haki to stay one step ahead of Luffy.
Enel is a moderately tall One Piece villain, measuring in at 266 centimeters in height. He celebrates his birthday on May 6th, meaning he is a Taurus, just like Arlong. However, Enel doesn't feel like much of a Taurus, since he'd rather have his minions do most of his dirty work for him, while earth signs are all about work.
4 Charlotte Linlin

Charlotte Linlin, who also goes by Big Mom, is the captain of her enormous pirate crew and is one of the Four Emperors in the Whole Cake saga. Big Mom is definitely one of the series' most powerful female characters and one of the cruelest, too. She is not a giant, but she's as tall as many of them regardless.
Big Mom is One Piece's tallest human character overall, measuring in at an impressive 880 centimeters. Her birthday is February 15th, which falls under the Aquarius sign. That's an altruistic, idealistic air sign that believes in the power of the people, but Big Mom would rather have people serve her instead.
3 Charlotte Katakuri
Charlotte Katakuri made his debut in the Whole Cake saga, where he was clearly set up as Luffy's counterpart. Both of them are melee fighters who use stretchy Devil Fruit powers to fight, and they are both big eaters and are intensely loyal to their crew as family. Katakuri is also an expert at using Color of Observation Haki to predict his enemies' moves.
Charlotte Katakuri is a tall fellow at a huge 509 centimeters, towering over the likes of Doflamingo and Crocodile. He was born on November 25th, so his zodiac sign is Sagittarius, the fire archer. That sign likes to explore the world and return with exciting tales of what they saw, but Katakuri doesn't seem like the type to do that.
2 Gecko Moria
Gecko Moria was a warlord of the sea when Luffy's crew met him in the eerie Thriller Bark saga. Gecko was a scientist-like villain, tinkering with dead bodies and shadows to create new warriors in a Frankenstein-like lab. He didn't like fighting in person, preferring to use his zombies, including the massive Oars zombie, which he piloted from the inside.
Gecko is one of the tallest One Piece villains and is the tallest warlord, standing at 692 centimeters tall. He marks his birthday on September 6th, making him a Virgo. Like most Virgos, Gecko diligently works hard to accomplish his goals, always making new zombies to create the perfect undead army and hone his skills.
1 Kaido
The mighty Emperor Kaido was the primary antagonist of the Wano story arc, and Luffy fought an incredible battle with him on Onigashima Island. It was during that fight Kaido went all-out with his dragon form, pushing Luffy to finally awaken Gear 5 and even the odds against the world's strongest creature.
Kaido is quite tall in his humanoid form at 710 centimeters, though his length in his serpentine dragon form is unknown. Kaido's birthday is May 1st, so he is a Taurus. He certainly embodied that sign's love of earthly comforts during that drinking party on Onigashima, and he is certainly stubborn and uncompromising as a true Taurus bull.
