Luffy Gear 5 Fanfic: In the heart of a new island, Luffy stood tall in his Gear 5 form. His body pulsed with a vibrant red energy as he faced the powerful new foe. 'I won't let you harm my friends!' he roared. With a swift motion, he stretched his arm like a rubber band, then snapped it forward, sending a shockwave of Haki towards the enemy. The foe tried to dodge but was caught in the blast, sent flying backwards. Luffy then bounced around the battlefield, his movements a blur, leaving trails of light as he continued his attack.
They might be shocked. Luffy's Gear 5 is such a powerful and strange form. In the fanfiction, characters could be amazed at his new abilities, like his cartoon - like movements and seemingly limitless power.
In fanfiction, Luffy's character in Gear 5 might develop a greater sense of responsibility. Since Gear 5 is so powerful, he realizes he has to be more careful about using it. For example, he might avoid using it in areas where there are a lot of innocent bystanders.
Nami would probably be shocked at first. She might worry about how this would affect Luffy's journey to become Pirate King. But then she would likely start thinking about practical things like how to take care of the baby on the ship. Sanji would be over the moon, seeing it as an opportunity to cook for a new little life. He might also be a bit jealous that it's Luffy and not him having a baby with Hancock.
Luffy uses Gear 5 in a significant battle towards the later part of the manga. But the exact chapter or arc can vary depending on how you're reading it.
I think Shanks would have an interesting reaction. He has known Luffy since he was a kid. Seeing Luffy reach Gear 5, he would probably be proud but also a bit cautious. He might think about how far Luffy has come and also wonder what challenges this new power will bring for Luffy and the world at large.
One interesting idea could be exploring new abilities Luffy discovers within Gear 5 that he hasn't shown in the official story yet. For example, he might be able to manipulate his surroundings in even more creative ways, like turning the air into rubbery substances to create platforms or traps.
I think it's in a relatively recent chapter, but the exact one might vary depending on where you're reading the manga. You might need to check the latest updates.
