Sanji didn't want Big Mom to go after the Straw Hats It turns out that his family used him as a pawn for a marriage proposal. They wanted to marry into the Charlotte family to obtain more power.
As Sanji recovers, Luffy tells him to say how he really feels. Sanji then has memories of making food for the crew. He once got mad at Luffy, Usopp, and Chopper for sneaking food into their mouths, but the crew only had fun as they clamored for more of his cooking.
Sanji left the Straw Hat crew during the Zou arc in order to protect Zeff and the Straw Hat Pirates present there from the wrath of Big Mom. To retrieve him, Luffy went to Whole Cake Island and Sanji ended up fighting him to drive him off for his safety and to make sure Zeff survives.
Luffy may have gotten a bit wiser but his personality didn't change post timeskip. That's why Sanji fought him because he knew that's how Usopp left the crew. Sanji wanted Luffy to know he was serious about leaving so he fought enough to knock Luffy out.
In spite of Luffy's gluttony, he does care for Luffy, and, as the best swimmer on the crew, he is shown dragging his captain out of the water more often than any of the other crew members.
5 Pudding Betrays The Straw Hat Pirates
In the Whole Cake Island arc, Pudding tried to help the Straw Hat Pirates, however, she was actually leading them into a trap. She betrayed not just the Straw Hat Pirates but Sanji as well and was planning on killing him and his entire family.
1 Nami Was Sanji's First Love
Nami was the first woman Sanji ever showed interest in. He became enthralled by her charms seconds after seeing her in the Baratie and has remained so ever since.
It's among the more heartbreaking scenes in One Piece history. Luffy doesn't bother fighting back, since he knew that Sanji was forced into this position. Nami even slaps the taste out of Sanji's mouth, angered by his betrayal.
Morgans' Betrayal of Luffy Shows He is Unpredictable
This philosophy recontextualizes a lot of Morgans' past actions.
7 LOVED HIM: Unwavering Loyalty To Luffy
Back at Thriller Bark, Sanji tried to stop Zoro from giving his own life to save Luffy.
Charlotte Pudding is a supporting character from the anime and manga series, One Piece. She is Charlotte Linlin's 76th child and 35th daughter, and one of Charlotte Linlin's favorite daughters. She was arranged by her mother and Vinsmoke Judge to marry the Straw Hat's cook and Judge's estranged son, Vinsmoke Sanji.
5 Zoro & Sanji Are Like Best Friends & Rivals
Both Zoro and Sanji care deeply about each other even though they're in competition with each other. Sanji has risked his life to save Zoro on several occasions and Zoro wouldn't hesitate to do the same for the cook of his crew.
Judge exhibits a typical royal hauteur, holding the firm belief that royalty is meant to be served, not to serve others. He disowns his third son, Sanji, after learning about Sanji's "disgusting" habit of cooking for others (which he equates with serving others).
Saji treats women with high respect (and pervertness, if thats what I would call it), he even has said it a lot of times that "I'd never kick a woman". Thats the exact reason that Zoro doesn't like him.
Zoro x Hiyori
The Wanokuni arc of One Piece gave Zoro the spotlight he deserved but fans were more gravitated toward his scenes with Hiyori. It wouldn't surprise fans if Hiyori reveals her feelings for Zoro, her savior. They shared intimate moments and Zoro might even find a sense of belongingness when he's with her.
That said, there is one crew member who stands above the rest in terms of loyalty to Luffy: Roronoa Zoro. The Straw Pirates' first mate has proven his loyalty on numerous occasions throughout the series, even putting his crew mates' well-being above his own life.
Sir Crocodile was the main antagonist of the Alabasta arc of the series and the first Shichibukai that Luffy took down. Crocodile is easily one of the most difficult fights that Luffy has ever fought as he lost to him twice. In fact, Luffy would've died both the times had luck not been on his side.
Law. Blackbeard is set up to be protagonist Monkey D. Luffy's final villain; the fight between these two Yonko's is sure to be an enthralling duel.
Perhaps the most emotional departure in the series, the ship's cook Sanji left the crew after receiving an invitation to a wedding: His own. Sanji's biological father Vinsmoke Judge decided to marry his son off to Charlotte Pudding, the daughter of the powerful pirate Big Mom.
Aokiji not only defeated Sanji, but he also took down both Zoro and Luffy as well.
Nami also claimed she wouldn't forgive Sanji for all worry and pain he put her through on Whole Cake Island; however, she did expressed happiness when he saved her from falling while escaping the Tea Party.
Upon listening to her mockeries and insults of him, Sanji was left with a broken heart, crying silently in the rain. On the day of the wedding, Pudding expressed dismay at the thought of her dress becoming splattered with blood after killing Sanji (whom she referred to as an "idiot").
