Sanji's Newly Acquired Power Ifrit Jambe Explained!

Surtr, a figure in Norse mythology, is either a fire demon or a primordial giant known as a Jötunn. He was the first fire giant to rule over the fiery realm of Muspelheim, where he served as its guardian, standing at its border with a flaming sword.

During the event known as Ragnarok, which marks the end of the world in Norse mythology, Surtr is fated to lead the fire giants in a battle against the gods. He is regarded as one of the two "supreme evils" in old Scandinavian myths, the other being Loki. Surtr's name means "Black" or "The Swarthy One" in Old Norse. The Jötnar, plural for Jötunn, are often seen as "the opposite of the gods" in Norse myths.

Some highlighted connections here:

• Fire demon
• Loki connection (Both Sanji and Loki are princes)
• Surtr’s name means “black” and Sanji have a black epithet.
• The Opposite of the Gods (Sanji is/will be a D?)

During their time at Thriller Bark, Zoro had warned Usopp that Sanji's anger might cause him to transform into something. In his battle against Queen, Sanji claimed that his flames were fueled by his passion, and thus, he could still increase their intensity even further, as his passion was unmatched. Sanji also mentioned that his newly upgraded exoskeleton and Armament training had allowed his legs to withstand the heat of his flames. This meant that he could fight for a prolonged period, although his legs might not be able to endure the impact and heat.

In Islamic mythology, the Ifrit, also spelled as efreet, afrit, and afreet, is a powerful type of demon associated with the underworld. They are often linked to the spirits of the dead and have been compared to malevolent geniī loci found in European culture.

As a personal theory, I believe that Sanji's Diable Jambe would be represented by orange/red flames, while Ifrit would have blue flames. The third stage, Surtr, would be depicted with black flames. This could be symbolic of Oda's use of the number "3" in Sanji's character, including the three stages and three flame colors.

Sanji

"Black Leg" Sanji is a pirate and the cook of the Straw Hat Pirates, and the former sous chef of Baratie. He is officially the fifth member of the crew and the fourth to join, doing so at the end of the Baratie Arc. Since he was born in North Blue, he is the first Straw Hat not to originate from East Blue. He is one of the Monster Trio in the crew alongside Luffy and Zoro. His dream is to find the rumored All Blue, which is where East Blue, West Blue, North Blue, and South Blue meet along with their wildlife, a chef's paradise. He has a bounty of 177,000,000Beli, which is only valid if captured alive.

Sanji is a slim, yet muscular, long-legged young man with blond hair and keeps his hair brushed over one side of his face. For the initial part of the series, this was the left side. Due to his left eye never being seen, many fans questioned whether he had one at all. In the manga it was usually covered one way or another, but is seen in the anime. Later, after the two year timeskip, he switched his hairstyle so that it covers the right side. It also appears that Sanji's hair is less straight and scruffier after the timeskip.

Among Sanji's physical traits are his distinctive eyebrows. Both form a spiral but at different ends. His right eyebrow forms a spiral at the outer end, while his left eyebrow forms a spiral at the inner end. This means his face is asymmetrical with the position of his eyebrow spirals. This, however, is not fully seen due to his hairstyle. He still gets very upset if somebody, typically Zoro, mocks him over the spirals. Though, on rare occasions, Sanji's other eye was seen in the anime, the spiral was never witnessed. While Sanji's eyes usually seem black, he was depicted with grey-blue eyes in the anime at the beginning of Thriller Bark Arc. Sanji almost always wears a black, double-breasted suit with a tie and a long-sleeved, buttoned shirt of varying colors, usually orange, blue, turquoise, or black, with or without pinstripes. His outfit changes on a more frequent basis than most of the crew.
