#5 – Charlotte Cracker’s Bisu Bisu no Mi
Cracker ate the Bisu Bisu no Mi, a Paramecia-type Devil Fruit that allows him to generate and manipulate biscuits at will. Cracker is an expert craftsman, shaping his biscuits into identical, hulking, and lifelike entities complete with weapons. He usually inhabits one of his puppets as a suit of armor. It took the immense raw power of Gear Fourth, Luffy’s strongest state, to inflict significant damage on the armor. By creating even more suits of biscuit armor, Cracker can create a large, defensive wall that will absorb powerful blows while he prepares to attack.
#4 – Sengoku’s Hito Hito no Mi, Model: Daibutsu
Sengoku ate the Hito Hito no Mi, Model: Daibutsu, a rarer-than-Logia Mythical Zoan-class Devil Fruit which allows him to turn into a gigantic Daibutsu. This ability gives him a massive power boost to his already impressive strength, enough to cause the execution stand to collapse in one indirectly connecting punch, despite the combined effort of Luffy’s Gear Third and Mr. 3’s Candle Wall to absorb the attack.
#3 – Bartolomeo’s Bari Bari no Mi
Bartolomeo ate the Bari Bari no Mi, a Paramecia type Devil Fruit which allows him to be a Barrier Human. His barriers are seemingly indestructible, as attacks from powerful individuals such as Hack, Bellamy, and Gladius had no effect, and even Elizabello II’s “King Punch” could not damage the barrier. The previous user of Bari Bari no Mi Kurozumi Semimaru demonstrated that the barrier can also withstand an extremely powerful slash from Kozuki Oden, whose swordmanship could cut the gigantic Mountain God in half and even damage the near-invincible Kaido.
#2 – Jozu’s Kira Kira no Mi
Jozu ate the Kira Kira no Mi, a Paramecia-type Devil Fruit that allows him to transform parts and most likely all of his body, into diamond. His defenses seem to enhance exponentially, as he is able to block the strongest slash in the world from the world’s greatest swordsman, Shichibukai Dracule Mihawk, with no visible damage to himself, as diamond is one of the hardest substance in the world along with Seastone and the Poneglyphs.
#1 – Marco the Phoenix’s Tori Tori no Mi, Model: Phoenix
Marco ate the Tori Tori no Mi, Model: Phoenix, a mythical Zoan-type of Devil Fruit. The fruit’s greatest attribute, however, is that Marco can recover from any damage he accumulates in his human form by reverting to his phoenix, or hybrid phoenix form, or just by summoning blue flames around his body. These blue flames are not hot and they do not burn or spread like normal fire; instead, they are what allow him to heal, and are referred to as the “Blue Flames of Resurrection”. The healing properties of his blue flames can also be used to treat other beings, albeit to a more limited extent, allowing Marco to act as an efficient doctor.
Though the phoenix flames do not burn or spread like normal fire, they are still considered a special form of flame much more potent than normal fire, proven when Marco overpowered Big Mom’s “special” fire homie Prometheus, the phoenix fire causing the latter pain. Marco also used his flames to revert the effects of Queen’s virus Ice Oni.
