Sir Crocodile is the former president of the mysterious crime syndicate Baroque Works. He was originally introduced as a Shichibukai but was later stripped of his title after attempting to take control of the desert kingdom Alabasta. Thanks to Luffy, he managed to escape from Impel Down and went to Marineford to participate in the war; after that, he and his subordinate Daz Bones decided to head out to the New World.
Crocodile ate the Logia Devil Fruit, Suna Suna no Mi, allowing him to become, generate, and manipulate sand. He has mastered his ability to the point of perfection and can turn into sand reflexively if attacked; this became especially obvious after Doflamingo cut his head off while he was distracted.
PORTGAS D. ACE
Ace was the 2nd division commander of the Whitebeard Pirates and one-time captain of the Spade Pirates. He was the adopted older brother of Luffy and Sabo, and son of the late Pirate King, Gol D. Roger and his lover, Portgas D. Rouge.
Hunted by the World Government for his lineage, Ace was captured and sentenced to death, which resulted in the Battle of Marineford in an all out clash of powers. Ace was freed, but he sacrificed his life to protect his younger brother Luffy from Akainu.
Ace ate the Devil Fruit Mera Mera no Mi, a Logia-type fruit that allows him to become the element of fire and control the flames from his body, giving him his reputation as “Fire Fist Ace”. Aside from the powers granted by the Devil Fruit he consumed, Ace possessed immense physical strength.
Morley is an okama giant and the commander of the West Army in the Revolutionary Army.
Morley ate the Oshi Oshi no Mi that allows him to push away any substance. Seemingly a Paramecia-type Devil Fruit, using this power, he can easily move underground, as well as attack enemies by pushing clumps of ground onto them, as it seems to otherwise maintain its original weight and hardness.
Over 100 years before the start of the story, Morley was a wanted pirate who was imprisoned at Impel Down. Somehow, he managed to escape the prison, a fact that remained unknown for a long time allowing the prison to keep its status as being unbreakable until Shiki’s escape many years later. The tunnels Morley carved with his Devil Fruit abilities would later be known as the Level 5.5, which housed the Newkama Land.
As a giant, Morley possesses tremendous physical strength and a longer lifespan when compared to humans.
Ivankov is the “Queen” of the Kamabakka Kingdom, known as “Okama King” and a “Miracle Person”, and is one of the commanders of the Revolutionary Army.
He was formerly a prisoner of Impel Down kept in Level 5, living in a secret “Okama Paradise” in level 5.5, but has since returned to his post as Queen of Kamabakka Kingdom.
Ivankov ate the Horu Horu no Mi, which allows him to control the hormones of the human body, and is one of the very few known powers coming from a Devil Fruit that can affect other people’s bodies as well as his/her own. This power led him to be known as the “Miracle Person”.
In contrast to his rather comical appearance, Ivankov is a powerful fighter should the need arise. He is an extremely powerful grandmaster of a martial art called the Newkama Kenpo.
Jinbe was the second captain of the Sun Pirates after Fisher Tiger, and a former Shichibukai, who attained the position eleven years ago. Sometime after Ace’s capture, Jinbe was also imprisoned in Impel Down, due to being the only member of the Shichibukai who refused the summons of the World Government to stand against the Whitebeard Pirates. Currently, Jinbe is is officially the tenth member of the Straw Hat crew and the ninth to join Luffy’s crew.
Jinbe is the most powerful fish-man seen thus far. He is is an exceptionally powerful master of Fish-Man Karate.
He is also extremely skilled in using Busoshoku Haki, as shown when he hardened his arms to defend himself against Big Mom’s Cognac.
Catarina Devon, known as the “Crescent Moon Hunter”, was the most dangerous female pirate ever to be imprisoned in Impel Down within the entire age of pirates. She was freed by Marshall D. Teach and is currently the only known female member of his crew.
Devon ate the Inu Inu no Mi, Model: Kyubi no Kitsune, a Mythical Zoan-type Devil Fruit that allows her to transform into a nine-tailed fox. With this power, she can transform into clones of people similar to the Mane Mane no Mi.
The greatest strength of this fruit is that the user is also capable of transforming into other people, allowing them to impersonate them.
SHILIEW OF THE RAIN
Shiliew of the Rain was the Head Jailer of Impel Down until he was imprisoned for his excessive violence towards the prisoners. Due to the riot caused by Monkey D. Luffy and the arrival of Marshall D. Teach, he was temporarily released to help quell the riot. However, instead of dealing with the pirates, Shiliew assisted Teach and ultimately decided to join his crew. He is currently the Captain of the Second Ship of the Blackbeard Pirates.
Shiliew is extremely proficient in wielding his nodachi, having used it to kill numerous prisoners of Impel Down, all who were noted to be powerful and dangerous criminals. When his sword was returned to him after a long term imprisonment, Shiliew killed several of his fellow Impel Down officers in a split second, demonstrating extraordinary precision and dexterity in his swordsmanship.
Shiliew has eaten the Suke Suke no Mi, a Paramecia-class Devil Fruit which gives him the ability to turn himself and other things invisible. With this fruit, he is able to cut opponents without being spotted, taking them by surprise.
Donquixote Doflamingo was the captain of the Donquixote Pirates, a former Shichibukai, the most influential underworld broker under the codename “Joker”, and is a former World Noble of the Donquixote Family descent.
After he was defeated by Monkey D. Luffy near the end of the Dressrosa Arc, he was arrested alongside most of his crew members by Admiral Fujitora and locked up at Impel Down Level 6.
Doflamingo is one of the most powerful pirates to appear so far. He has displayed physical abilities of superhuman strength, reflexes, spryness, dexterity and speed, with excellent reaction time.
Doflamingo ate the Ito Ito no Mi which was given to him by Trebol, granting him the ability to create and manipulate strings. He usually moves his fingers accordingly to bend them as he pleases for either manipulating people like puppets or bifurcating his targets. The strings are extremely thin and some may even be invisible, making it almost impossible to notice and avoid them. Doflamingo’s mastery of his Devil Fruit is so advanced that he was able to awaken his powers, being able to even turn his surroundings into string. The great extent of his Devil Fruit abilities led the Marines to wrap him in Seastone shackles upon his arrest, even though a single pair of handcuffs can neutralize Devil Fruit powers.
MONKEY D. LUFFY
Luffy has a worldwide reputation for causing trouble, challenging the Shichibukai, the Marines, and two of the Yonko (Big Mom and Kaido), additionally committing felonies and actions which were deemed threatening by the World Government. Furthermore, in the majority of these confrontations, he emerges as the victor.
At the beginning of the Reverie Arc, Luffy’s achievements were compiled, greatly inflating his infamy, which was already immense to begin with. This includes his relationship as a sworn brother to both the late commander of the second division of the Whitebeard Pirates and the son of Gol D. Roger, Portgas D. Ace, and the Revolutionary Army Chief-of-staff, Sabo; the Fleet that unofficially formed under him; the infiltration operation of Big Mom’s territory, Totto Land, where he defeated Sweet Commanders Charlotte Cracker and Charlotte Katakuri, attempted an assassination on Charlotte Linlin herself, destroying her castle (unintentionally), and created a prompt alliance with Germa 66, the Sun Pirates, and the Fire Tank Pirates before escaping after the assassination had failed. Though his capabilities were slightly exaggerated by the press, his achievements were great enough for him to be unofficially titled the “Fifth Emperor of the Sea”.
SHIKI THE LION
Shiki the Golden Lion, also known as the “Flying Pirate”, is the admiral of the Golden Lion Pirates. During the Roger Era, he was one of the most powerful figures of the time, being on par with Sengoku, Garp, Whitebeard, and Roger. Shiki is the first known prisoner ever to escape from Impel Down.
Shiki possesses great skills in swordsmanship as he dual-wielded Oto and Kogarashi to single-handedly massacre an entire army of Marines before getting subdued by Garp and Sengoku.
Shiki ate the Fuwa Fuwa no Mi, a Paramecia type Devil Fruit which allows him to make surrounding non-living matter levitate once he has come in contact with it.
He seems to have mastered the use of this fruit, as he has shown a variety of skills which manipulates the surrounding non-living environment in complicated ways, even manipulating it from its simplest components, such as earth’s fragments and snow flakes being used to build up gigantic, elaborate structures that are then used to attack for a variety of purposes. When attacking, Shiki uses the surrounding environment against his enemies, shaping earth or snow into giant lion heads and launching them towards his foes, or even making water float to drown his opponents in it.
