There has been only one exception: after his fight with Usopp in Water 7, Luffy did not smile for the longest time in the entire series while non-combative; in the storyline, he did not smile for a whole day, but in terms of chapters, he did not smile for fifteen chapters.
The only exception was against Usopp, where he cried after winning. In fact, at that time, Monkey D. Luffy did not laugh or smile for an entire day because of that battle. In terms of chapters, it lasted for 15 consecutive chapters, making it the longest period in which he did not smile or laugh.
However, what many people don't know is that Oda deliberately simplified his face and overall design. This way, it wouldn't be too difficult for him to draw Luffy's simple appearance, making it easier for him to convey his wide range of emotions.
Similarly, in the Impel Down arc, Ivankov took 10 years of Luffy's life, which was a daunting decision for Luffy to accept. He was injected with hormones to be able to continue fighting, at the expense of years from his lifespan.
As far as i can remember, he cried three times (not including when he was kid); First time during Water 7 after his fight with Usopp, second time after Ace's death and third time after he found out Sabo was alive.
Luffy is just a kid, he a boy not asexual.
He cried twice. The first time when Kuina died. The 2nd time when Mihawk defeated him.
Possibly. Especially when both gear 3 and 4 has side effects. (Gear 3 side effects are gone after time-skip & gear 4 = loss of haki temporarily). I believe Luffy is going to have a short life though, him taking hormones once impel down to save his life and with his abilities.
However, his true dream, revealed in Episode 1088, is something much bigger, which he wants to accomplish after becoming Pirate King. Fans speculate his ultimate dream could involve, throwing a worldwide feast where everyone—pirates, marines, civilians, minks, and more—comes together.
While it was the first time many strong characters in the One Piece world saw Luffy use Haki, he had technically used it unknowingly twice before the Marineford arc: Against the bull Motobaro in Episode 389. Against the Boa Sisters at Amazon Lily in Episode 413.
He later wears a red vest, denim shorts, and sandals, before replacing his vest with a red, unbuttoned sea captain's coat (revealing the X-shaped scar on his chest he received from Akainu), and a yellow sash tied around his waist. In an interview, Eiichiro Oda said Luffy's real-world nationality analogue is Brazilian.
Hardening is an armament haki technique where the user hardens their skin with a heavy concentration or coating of haki which results in the black coloring. When Luffy first uses armament hardening and his arm turned black Ussop commented on it and he was not a haki user at the time.
It's Nico robin. She's the only person who never hit him.
One Piece: Why Luffy's Final Fight Will Break Shonen (& It Won't Be Against Imu or Blackbeard) - IMDb. One Piece fans have been wondering about the final antagonist who will face Luffy, and it is none other than the mythical Sun God Nika himself.
The official answer is that Luffy can stretch a distance of "72 gomu-gomus". He can apparently increase this limit by training is is aiming for 100 gomu-gomus.
Boa Hancock's relationship with Luffy evolves from bewilderment to fondness after he saves her life.
One major idea that gained a lot of traction in the One Piece community is that “D” in “The Will of the D” actually stands for the word “Devil.” This would make characters like Luffy, Monkey Devil Luffy, and place him as a member of the Devil Clan.
Short Summary. The last standing fighter is revealed to be Rebecca, making her the winner, much to the dissatisfaction of the disbelieving audience. Rebecca was the only one to saw what really happened during the fight.
Using Gear Five burns through his energy fast. So when Loofy overuses it, he runs out of stamina and his body temporarily breaks down showing signs of sudden aging or dehydration looking like an old man. It's like the drawbacks from Gear three and Gear four but way more extreme.
Instead of living to 80, he'll live to 70. And Gear 2 could kill him if he overused it (we see it affect him in Enies Lobby and Thriller Bark.) However, since the time skip, Luffy has had no problems using Gear 2 whenever he wants without any consequences. Seems like his body adjusted to his fast heart rate.
There is an unspecified limit to how long he can keep Gear 4 active, as noted by both Luffy himself and Doflamingo. Once this limit is reached, Gear 4 automatically deactivates, leaving Luffy exhausted and barely able to move.
None of the women have kissed Luffy, but the first to lock lips with him is Reiju when she gave him mouth-to-mouth. In the anime, Marguerite bathed an unconscious Luffy whilst still clothed, in the manga she is naked herself. Rebecca notably allowed Luffy to sleep on her lap after his victory over Doflamingo.
During his childhood, Zoro was seen blushing when Kuina mentioned her figure was beginning to develop. When he first met Tashigi, he was visibly shocked by her strong resemblance to Kuina and whenever he encountered her, he would constantly try to run away unable to face her.
