A scene of young Sanji beginning to smoke during his early days at the Baratie was not shown in the anime, possibly because it showed a child smoking and implied that smoking was a way of seeming mature.
The manner in which Zeff lost his leg was also altered. While the anime showed him cutting off his leg in order to escape an anchor's chain and get Sanji safely to shore, the original story in the manga implied that he had eaten his own leg in order to survive while he and Sanji were stranded, as he had given Sanji all of their food rations.
Like all of the Straw Hats, (except Luffy) his time alone after being teleported away by Kuma was extended in the anime.
It showed that he was treated by what appeared to be a beautiful woman named Tibany. Sanji then followed her, only to discover that "she" was an okama. Unfortunately for him, due to a miscommunication between the two of them, Sanji is interpreted as an okama and is soon seen running away. The anime version shows Caroline (the substitute Queen of Kamabakka Kingdom) turning Sanji into an okama. Later, upon receiving the news about Ace's death and the Battle of Marineford, the shock of it turns him back to his usual self.
Also in the anime, Sanji instantly falls in love with Ivankov's female form, despite knowing "she" would not be interested in men. He attempts to ask about Luffy through gestures of romance. He snaps out of it when Ivankov turns back into a man, angering Sanji and crushing his hopes of meeting a real woman.
Their fight is shown, with Sanji attacking Ivankov with Diable Jambe. Ivankov pretends to be defeated by this but then effortlessly overpowers Sanji, surprising his Okama followers. Iva then unleashes a barrage of "44 - Aesthetic Technique! Hair Removal Fist", "Death Wink", "Hell Wink", and "Galaxy Wink" leaving Sanji on the ground bloodied and beaten to an inch of his life. Ivankov then hands Sanji a newspaper since the news of Luffy has already been made public.
In the manga, after one of the okamas tells Sanji that they hope to see him again, he replies by saying he does not want to see them again showing "the finger". In the anime, this was censored so he replies with the same answer but puts his right hand across him and moving it to the lower right.
Sanji's lighter seen during the Punk Hazard Arc and in One Piece Film: Z. It was given a realistic version made by DuPont. The lighter was designed by Oda himself. It has the shape of a woman sitting, leaning on her legs.
Sanji makes a cameo appearance in Sayonara Zetsubo Sensei. During the character Meru's introduction, Harumi is seen reading a yaoi manga featuring Sanji and Zoro. Also, in her room, there are action figures of Luffy, Zoro, Sanji and Sogeking. Also, in the same series, during Nozomu's escape from an evil organization, his silhouette is visible along with the silhouettes of Nami, Luffy, Usopp and Zoro plus two unidentified pirates; one that could be Robin and one that looks like a human version of Chopper's Heavy Point wearing a sash and a bandanna.
In the MMO fighting game Rumble Fighter, a user suggested a Sanji based fighting style for the game using sprites from a Wonderswan One Piece game in order to give the developers a general idea. The developers liked it, and decided to create this fighting style, although naming it "Red Leg" instead of the actual name, "Black Leg".
In the anime Working! there is a character named Satou Jun who closely resembles Sanji, due to them both sharing the same appearance, both working as chefs and both seen to regularly smoke.
Sanji is the main protagonist of "Shokugeki no Sanji"; a crossover between "One Piece" and "Shokugeki no Soma" featuring Sanji preparing a meal during his days working at Baratie. Other Baratie staff members also appear, and at the end of the first chapter, the Straw Hat Pirates are approaching the restaurant.
In the original Japanese manga, the Japanese anime, the uncut FUNimation dub, and the Viz English manga, Sanji is a chain smoker. In the 4Kids anime, Sanji instead sucks on lollipops (because of the audience the dub was aimed at). For the aired, edited FUNimation version, the cigarette was completely edited out and any scenes that show him lighting cigarettes or other such actions were redrawn. The same was done in the Singaporean English dub by Odex.
The lollipop from the 4Kids version.
The cigarette from the original.
In the FUNimation subs his epithet of "Black Leg" (黒脚 ,Kuroashi) is translated as "Black Foot". This is because Ashi can translate as either "Leg" or "Foot".
In the English-language manga, Sanji often uses "Crap" as an adjective while speaking (when calling Crocodile, he refers to the restaurant as "Restaurant Le Crap" ("Crap Café" in the uncut FUNimation dub). This is an attempt to convey both his extremely coarse speaking style in Japanese, as well as his use of "kuso" (roughly "feces") as an expletive; fans often translate it as "shit" because of his manner of speech. For example, he often calls Zeff "Kuso-Jiji" (roughly "shitty-geezer"). In other fan translations, it is rendered as "old fart" or "old man".
In the English anime produced by 4Kids, he simply calls Zeff "old-geezer" or "old fart" (in fansubs, he is also referred to by this name), and "crap-geezer" in the English manga. Also, in the 4Kids English dub, Sanji has an extremely nasally Brooklyn accent, while in the FUNimation version, there is no accent.
In the French dub, Sanji is renamed "Sandy". It was also the case in the French manga until the 67th tome and the start of "original" editions.
Sanji's personal jolly roger (post-timeskip) as detailed in the One Piece Magazine.
Baby Den Den Mushi displays Sanji's eyebrows prior to the timeskip.
Sanji has his own jolly roger, as does the rest of the crew. It has Sanji's right curly eyebrow, fork and knife for cross-bones, and a chef's hat placed on the top of his head.
His post-timeskip jolly roger is similar, except his chef hat is slanted to the right which hides his right eye, the skull has a goatee and cigarette, and the crossbones fork has four prongs instead of three.
Sanji's left eye was considered one of the "mysteries" of One Piece. As of Chapter 598, the mystery has been solved. After the two year separation, Sanji's hair style changed revealing his left eye and covering his right. This also reveals Sanji's eyebrows are asymmetrical, with both featuring a clockwise curl on the right hand side, and were both halves of Sanji's face to be uncovered at the same time, this anomaly would be fully apparent.
As a child, Sanji was imprisoned and forced to wear an iron mask. This resembles the story of the Man in the Iron Mask, allegedly a member of French royalty who was imprisoned in a similar manner.
Duval shares this resemblance, although he wears a mask from choice to hide his face.
The reason for Sanji's massive nosebleeds is from the joke that Japanese people have high blood pressure. Therefore, they get nosebleeds when they are sexually aroused. This joke is a very common cliche in manga and anime.
Sanji has smoked two brands of cigarettes, King Ground and Death.
There is a plot hole in the series when Sanji is unaware of a Devil Fruit user's inability to swim in the Baratie Arc, but he states that he became aware of this when he was a kid during the Thriller Bark Arc.
Sanji has a habit of saying "Mellorine" (an alternative to ice cream made from fats other than the butterfat normally used in ice cream) when looking, talking, or commenting about a beautiful woman. This carries over to the FUNimation English dub. His personalized honorific for Nami "Nami-swan" (developed from san) also carries over.
While he became a wanted infamous pirate Sanji faced many irritations:
Being an unknown pirate he lacked a bounty.
Because they lacked a proper photo the Marines used a crude drawing of him.
His "Only Alive" status the result from his family.
His bounty being higher than Zoro's only after his status as a Vinsmoke is revealed.
Sanji shares some similarities with the Revolutionary Army's Chief of Staff, Sabo. They are both blond-haired royals who rejected their lifestyle, and their new families were threatened by their biological fathers as a result. Both also use fire-based powers (Sabo through his Mera Mera no Mi, and Sanji through his Diable Jamble).
Sanji is the only Straw Hat shown so far to have biological siblings; Nojiko is Nami's adopted sister, while Ace and Sabo are Luffy's sworn brothers. Ironically, while Nami and Luffy adore their siblings, Sanji and his brothers actively despise each other.
In the Pirate Warriors series of video games, Sanji cannot attack female characters. This applies to both when the player is controlling him and facing female enemies, as well as when the player encounters him as an enemy while controlling a female character. When selecting a stage where female characters appear as enemies, if Sanji is selected by the player, a warning box will appear that points out Sanji's weakness to female characters and the player will be given the option to change to another character or ignore it and play the stage as Sanji. Generally there are two methods for dealing with female characters while playing as Sanji in the Pirate Warriors series: one is to avoid fighting them if possible (this may not be possible if a female opponent's defeat is required), while the other is to use support characters to deal with female opponents.
In Pirate Warriors 2, even if Sanji is affected by a Mad Dial, he will still retain his principle and will not kick any women.
In One Piece: Burning Blood, Sanji has a special attack "I won't kick a woman, even if it means my death!" that causes all his attacks (including his special and ultimate moves) to comically change into hearts and causes his health meter's portrait and the face on character model to change to his "heart eyes" face, when fighting female characters (as well as Bentham who is considered a female character in his DLC "Nami Mode" form). Unlike the Pirate Warriors series, Sanji can still attack female characters and "hearts" he produces can cause minor damage to female opponents. However Sanji is still weak against female characters.
In Chapter 831, an illusion of Sanji is seen with a lollipop instead of a cigarette which matched with his appearance in the 4Kids dub.
If Sanji became president, he would pass laws that would give extreme preferential treatment to women and discriminate against men. This would result in the men forming a rebellion against him and Sanji losing his position.
Sanji is the only one of the five Vinsmoke siblings to inherit his parents' blonde hair color because the genetic modifications of the other four changed their hair colors in the process.
Sanji's favorite foods are spicy seafood pasta and stuff that goes with black tea. His least favorite food is konjac because it has no nutritional value.
Sanji also does not like ice cream, the same as Zoro, Nami and Franky.

Fan question: About the mystery of Nami-san's New World bust size from volume 66, I would like to provide my opinion as an employee at LADIES' INNER. Nami-san's bust size is most likely a "J Cup". There is a possibility that she may have even grown bigger than this. ...If my calculations are correct, her band measurement is 63 cm, and her bust is 98 cm. If we were to use these measurements, she would end up being a "K"; however, right now in Japan, there is no such thing as a "K" cup. She'd have to order from overseas. Oui, in other words, non-standardized!!! Well, personally, I'd say that Nami-san is a "Nami Cup". (Boiing)
