In One Piece, there are many characters that use the fire element as their attack technique.
1. Pearl
This character appears when the Krieg pirates attack Baratie.
However, there was one time when Pearl used her special technique when she was bleeding.
2. Dragon on Punk Hazard
Luffy encountered a dragon for the first time when he arrived at the island of Punk Hazard which was half covered in fire.
3. Portgas D. Ace
Possessing the title `Fire Fist`, Portgas D. Ace ate the Mera Mera no Mi fruit and became the user of the ability to transform into fire as well as create and control fire.
However, it seems that Ace’s fire is weaker when compared to Akainu’s magma.
4. Sabo
Like Ace, Sabo also became a `man who controls fire` after consuming the Mera Mera no Mi during a gladiator match at Dressrossa.
Sabo combined his fire powers with the Ryusoken technique to create a move called Moeru Ryusoken: Kaen Ryuo, which was strong enough to take down Burgess.
5. Monkey D. Luffy
After training for two years, Luffy mastered Haki and created several moves with the fire element.
Then there is Gomo Gomu no Red Roc which is a stronger version of Red Hawk.
6. Sanji
Black Leg Sanji has developed his own fighting technique, by shooting fire from his feet to increase his attack power.
Then, the latest is the Ifrit Jamble – a technique born to increase Sanji’s body strength.
7. Roronoa Zoro
Zoro has a unique sword technique called Hiryuu Kaen.
When Zoro hit Ryuma, the wounds caused by Hiryu: Kaen created a fiery flame.
8. Franky
Franky can use fire attacks thanks to the cyborg technology on his body.
Before the timeskip, Franky’s technique was called Fresh Fire, where he would spit fire out of his mouth like a flamethrower.
9. Charlotte Katakuri
Although Katakuri is a Mochi Mochi no Mi devil fruit user, he can also use fire attack techniques.
His own fire fusion technique is Yaki Mochi – a technique that at first glance shares the same principles as Luffy’s Red Hawk.
10. King
King Fire is a powerful commander of the Hundred Beasts Pirates and one of the three powerful right-hand men under the Four Emperor Kaido.
Interestingly, King’s ability to create and use fire is innate, as he is the last descendant of the Lunarian race.
The size of King’s own flames also dictates the balance between his defense and speed.
11. Marco
Marco possesses the power of the mythical Zoan devil fruit Tori Tori no Mi, Phoenix model.
The blue flame has a unique characteristic: it does not spread and feels hot, it can even regenerate and heal everyone’s wounds.
12. Kaido
Four Emperor Kaido can create extremely powerful fire attacks.
