King's strength is far from ordinary; it falls into the category of 'rare and hard to come by.'
In One Piece chapter 1032, intriguing details emerged in the clash between King and Zoro. Witness how King adeptly countered all of Zoro's attacks. He escaped Zoro's Tatsumaki technique using his wings as a shield. Interestingly, King showed no signs of injury or fatigue facing Zoro.
The noteworthy point here is that Tatsumaki is a technique that previously wounded Kaido. This poses a big question for Zoro and fans about what King truly is and how he became so powerful. Zoro even wonders aloud if King's strength comes from his ancient Dragon Zoan abilities.

King himself doesn't deny this, emphasizing that his power surpasses that of a typical Dragon Zoan user and may even rival that of a Dragon. This leaves many wondering precisely what made King so powerful.
As many theories suggest, all of King's power is related to his origins. Confirmed reports state that King hails from the Lunarian race, considered a race of 'gods.' While the specific abilities of this race remain unknown, the name undoubtedly implies they are extraordinary beings.

Furthermore, although Zoro claims he has never seen King fly in his human form, it's plausible he did so when battling against Sanji, who was trying to protect Momonosuke. Another intriguing aspect of King is that when he's in hybrid form, there's no fire on his back. However, when King reverts to his human form, the flames on his body reappear. This could be the very flames on King's back significantly influencing his strength and defensive capabilities.
If this holds true, we can infer that Lunarians are a race with the ability to control fire. Therefore, the flames within King's body have an impact on his strength and endurance. When the flames on King's back appear or intensify, he becomes a formidable character, as witnessed in chapter 1032 when Zoro struggled immensely against King.

What might have happened to King is a fusion of the Lunarian human race's abilities and the powers of the ancient Dragon Zoan Devil Fruit. This is why King confidently declares himself different from other users. And if indeed the flames are King's 'source of power,' the next question is how Zoro can extinguish the flames to prevent his strength from increasing. This remains a significant question, and perhaps energy from the Supreme King's Haki could be the best current solution, especially now that Zoro has been officially confirmed to possess this 'power of a thousand men.'
