Vasco Shot, known as the “Heavy Drinker”, was one of the legendary criminals who was given a life sentence in Level 6 of Impel Down. He was freed by Marshall D. Teach and is currently a member of his crew.
He is currently one of the Ten Titanic Captains, and the captain of the Eighth Ship of the Blackbeard Pirates. As such, he’s one of the strongest members of the Blackbeard Pirates. He is strong enough to have been contained in Level 6 of Impel Down where only the world’s worst, most dangerous criminals are held. Even more, Vasco was among the strongest Level 6 inmates at the time of his confinement, as when Blackbeard recruited him alongside other prisoners, he chose only those who could survive when pitted against all other Level 6 prisoners in a free-for-all battle royale.
Due to the bionic modifications done to his body, Franky has incredible superhuman strength and durability.
The state of the art technology designed by Dr. Vegapunk, with nearly all of the futuristic and technological aspects of the Marines and the world as a whole (i.e. the Pacifista project and the assimilation of Devil Fruits into weapons) have been incorporated into Franky’s upgraded bionic modification. With all this in mind, post-time skip Franky is truly a force to be reckoned with. The scientific weapons that Franky has displayed so far in the post-time skip are noticeably more offensive and destructive than his BF-36 weapons. So far, he has revealed explosive missiles housed in his large shoulders, and a modified “Coup de Vent” known as “Franky Radical Beam”, that fires a powerful explosive laser beam instead of air, along with other powerful weaponry.
The fact that he was able to have laser beams in his arsenal despite the fact it was said that only Vegapunk was able to create them further proves Franky’s engineering mastery. His engineering skills also extend to anatomy as he modified himself into a cyborg and was able to perfectly understand Vegapunk’s notes on animal modification and his Pacifista project.
Bartholomew Kuma is a Shichibukai and a former member of the Revolutionary Army with a bounty of 296,000,000 Berries. He was once feared as an extremely vicious pirate, earning himself the title, “Tyrant”. He is a type of cyborg, a human weapon called a “Pacifista” developed by Vegapunk.
Kuma is one of the few people to have completely defeated the Straw Hat Pirates, and is also the only character introduced so far that has defeated the crew single-handedly, twice.
Kuma ate the Nikyu Nikyu no Mi, making him a “Paw Man”. A Paramecia-class Devil Fruit, it gave him paw pads on his palms which give him the power to “push” or deflect anything, including the air around him allowing him to not only defend himself from attacks but also to push objects at great speed. Kuma has made numerous people “vanish” by slapping them with one of his hands. It is later revealed that he pushes them away, sending them flying to another destination, which he can choose, even if the destination requires several days to reach.
Kuma’s abilities can also be used to create massively destructive attacks. This is displayed by one of his signature moves, “Ursus Shock”, essentially a bomb made of highly compressed air created by pushing the air between his hands.
The full extent of her abilities has not yet been shown, but she is known to be the worst female criminal in the age of pirates, and was imprisoned in Level 6 of Impel Down. Catarina Devon is one of the most powerful female pirates to have ever lived. She is one of the four to survive the battle royale Blackbeard held among the Level 6 prisoners of Impel Down who themselves were the strongest criminals to be imprisoned.
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.
“Massacre Soldier” Killer is a member of the Kid Pirates. His style of fighting seems to rely mainly on agility and speed, which he uses to overpower his opponent before they can strike him, or to dodge attacks. He was capable of fighting head on with the fellow Supernova Urouge, though the latter had not increased his muscle mass. He was also capable of fighting head on with Roronoa Zoro at Wano Country.
Killer is seen wielding a pair of gauntlets equipped with scythe-like blades, which he dubs “Punishers”. The blades are capable of spinning around like buzzsaws or simply being used as hand scythes. These weapons can also be used to block other weapons, leaving the foe open for Killer to kick the enemy’s flank or other exposed areas. If spinned at enough speed, the Punishers can generate powerful soundwaves to inflict damage to its target from the inside. This, combined with the agility he has so far displayed in combat and the notion that he is not afraid to kill, makes him a formidable foe. Killer even managed to hurt Kaido with these weapons, a feat only a few people were capable of. Killer possesses the ability to use both Busoshoku and Kenbunshoku Haki.
