In the storyline of “One Piece,” Impel Down stands out as a floating prison overseen by the World Government, notorious for housing some of the deadliest pirates. From heroic figures to sinister antagonists, a wide array of pirates who’ve committed various offenses find themselves incarcerated within its walls.

The standout individuals are usually found on the lowest and infamous level of the prison, dubbed “Eternal Hell.” While it’s frequently whispered about as a myth, this floor actually holds criminals deemed exceptionally influential or dangerous. These criminals face either a life sentence or execution, their crimes supposedly being expunged from history. This floor houses some of the most formidable pirates ever incarcerated in Impel Down.

7. Sanjuan Wolf

The Seventh Titanic Captain

Current Affiliation: Blackbeard Pirates

Sanjuan Wolf hails from the West Blue and was mysteriously imprisoned. He consumed the Deka Deka no Mi, a Devil Fruit that grants size-shifting abilities, making him the largest giant ever, even surpassing ancient giants in their full form. He lived through Blackbeard’s unexpected battle royale among prisoners, which aimed to select new crew members. Remarkably, he managed to join the ranks of the Blackbeard Pirates and was appointed as one of its Ten Mighty Captains.

Regarding his enormous stature, it’s logical to categorize Wolf as a heavyweight, even among those listed in the “Eternal Hell” group. However, his destruction has yet to be explicitly shown. He was subdued by Monkey D. Garp, but at that point, he was already unconscious. His assumed destructive power is so immense that his crewmates typically prefer him to stay unconscious in most situations.

6. Portgas D. Ace

Fire Fist

Current Affiliation: Whitebeard Pirates

Portgas D. Ace, who was the offspring of Gol D. Roger but estranged from him, spent his childhood alongside Monkey D. Luffy and ultimately viewed him as a sworn brother. Tragically, at just 20 years old, he met his end at the hands of Sakazuki. Yet, Ace was an exceptionally strong pirate; his limitations merely highlighted the prowess of his adversaries rather than revealing any weaknesses on his part. Originally commanding the Spade Pirates, Ace later crossed paths with Whitebeard, leading to his capture and eventual inclusion in Whitebeard’s crew as Second Division Commander.

Ace demonstrated abilities on par with a warlord, triumphing over Hanafuda, a former ally of Kaido who once held the title before Ace defeated him. This victory earned Ace an invitation to join the Seven Sea Warlords, a position he chose not to accept. Furthermore, Ace had the ability to utilize all three forms of Haki and consumed the Mera Mera no Mi, a Devil Fruit that grants its consumer control over, creation of, and transformation into fire.

Sadly, Ace was susceptible to various types of Logia, particularly Blackbeard’s Yami Yami no Mi, a fruit that could counteract the effects of other Devil Fruits. This weakness ultimately resulted in his capture and imprisonment at Impel Down, which paved the way for Blackbeard’s ascension to warlord status. Tragically, Ace met his end during the Summit War.

5. Jimbei

Knight of the Sea

Current Affiliation: Straw Hat Pirates

Jimbei was once a soldier for the Ryugu Kingdom but later turned into a seasoned pirate known as one of the Sun Pirates. He had great respect for his captain, Fisher Tiger, who stood up for Fish-Man rights and led a significant rebellion against slavery in Mary Geoise. Following his captain’s demise, Jimbei assumed command of the Sun Pirates and attained the rank of Warlord, partly to secure pardons for his crewmates that were imprisoned.

Instead, he consciously relinquished this position to avoid engaging in the Summit War against Whitebeard. Whitebeard took control of Fish-Man Island as a means to safeguard it. Jimbei was liberated by Monkey D. Luffy, who aimed to rescue Ace. This marked the commencement of their friendship. Later, Jimbei parted ways from the Sun Pirates peacefully, with his comrades endorsing his ambition to be part of the Straw Hat Pirates crew.

4. Crocodile

Desert King

Current Affiliation: Cross Guild

Previously, the Crocodile held leadership at Baroque Works. His plan involved executing several strategies with the ultimate goal of claiming Alabasta’s throne. However, theoretically speaking, these attempts were thwarted by Monkey D. Luffy. Initially, they fought twice, with Luffy losing both times. But in their final battle, Luffy emerged victorious. Later, Crocodile was confined alongside many of his high-ranking officers in a detention facility. Interestingly, unlike most, he chose not to attempt an escape from captivity.

In addition to Galdino (Mr. 3), Bentham (Mr. 2 Bon Clay), and Daz Bonez (Mr. 1), he was imprisoned in Impel Down. He pleaded with Luffy to aid in his release, with the intention of attacking Whitebeard during the Summit War. This plan was later supported by Emporio Ivankov, who hinted at knowledge about Crocodile’s past that he didn’t want exposed. After the Summit War, Crocodile established and built the Cross Guild, inviting Dracule Mihawk to become his business partner. This guild specializes in hunting down marines for bounties that the Cross Guild has placed on them.

The character possesses the Suna Suna no Mi ability, making him extraordinarily powerful in manipulating sand and absorbing moisture. He’s demonstrated this power by defeating Young Monkey D. Luffy on two occasions, but ultimately suffered defeat during their second re-match. Despite this setback, he has undeniably shown himself to be a symbol of strength and resourcefulness, swiftly rebounding from his initial defeat to rise again.

3. Shiryu

The Second Titanic Captain

Current Affiliation: Blackbeard Pirates

Previously, Shiryu served both as a prisoner and the Head Warden in Impel Down. Despite the harsh treatment meted out to prisoners, including torture and other forms of punishment, Shiryu’s excessive violence drew attention. As a result, he was demoted to a level 6 prisoner and sentenced to death. Temporarily spared during Impel Down’s attack due to his strength, he was tasked with guarding the prison. However, it was made clear that his sentence would still be carried out once the crisis passed.

In the end, Blackbeard chose him for his pirate crew, joining four other level six prisoners in a fight-to-the-death competition. Facing death as an alternative, Shiryu opted for piracy and has sailed with the crew ever since. Although not always seen in combat, Shiryu has proven himself to be no pushover. Oda, a notable source, recognizes him as the second strongest member of the Blackbeard Pirates, though it’s unclear if this assessment includes Kuzan. Similar to Teach’s original followers and fellow prisoners, Shiryu was promoted to one of the Ten Titanic Captains as the crew grew. He possesses enough strength to wound Monkey D. Garp, and has enhanced his power with the Suke Suke no Mi, a Devil Fruit that allows invisibility for both the user and their surroundings. Shiryu employs this ability to launch unexpected and powerful sneak attacks on his enemies.

2. Donquixote Doflamingo

Heavenly Yaksha

Current Affiliation: Donquixote Pirates

Once upon a time, Donquixote Doflamingo was part of the elite Seven Sea Warlords. Remarkably, he gained favor with various powerful entities such as the World Government, the criminal network, the pirate ruler Kaido, and simultaneously. This remarkable feat was accomplished while he ruled over Dressrosa, a kingdom he seized in just one night. Prior to his rise to power, Doflamingo was a Celestial Dragon, but was subsequently reduced to poverty when his father, Homing, stepped down from the title. He then regained his influence by establishing the Donquixote Pirates, a crew whose initial members swore allegiance to him upon witnessing his Conqueror’s Haki.

Apart from Doflamingo, there’s a unique Devil Fruit he wields: the Ito Ito no Mi, granting him control over strings that can manipulate people and inflict harm. By awakening this power, he could even transform his environment into more strings. It took Luffy’s Gear 4 to finally bring him down. Post-defeat, Doflamingo lost almost everything he had worked tirelessly to create. He is now locked up in Impel Down, with just his signature red sunglasses as a keepsake from his time outside.

1. Shiki

The Golden Lion

Current Affiliation: Golden Lion Pirates

Once a member of the infamous Rocks Pirates, I ventured out on my own following their dissolution, building what was once known as the world’s largest fleet. My clash with Gol D. Roger at The Battle of Edd War resulted in a loss that fueled my determination to challenge the Marines relentlessly. This defiance ultimately led to my capture, serving time in Impel Down. In an act of desperation, I severed my own legs to free myself from the seastone shackles. With my two iconic blades now serving as prosthetic limbs, I made my daring escape.

For approximately two decades, he devised a scheme to release genetically altered creatures worldwide, a plan only visibly enacted within the non-canonical film “Strong World.” Despite this movie’s outcome showing the Straw Hat Pirates defeating the fleet, Shiki has been confirmed as canon. His storyline in the film remains the singular aspect of his character not to intersect with the main series. However, his Devil Fruit power, the Fuwa Fuwa no Mi, which enables levitation and floating objects through telekinesis, has also been validated as part of the canon. Given his exceptional execution of this ability and being the second inmate ever to escape from Impel Down (the first was Morley from the Revolutionary Army), it can be argued that he was the strongest prisoner held within the confines of Impel Down, according to the canon.
