CATARINA DEVON
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
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.
