where does luffy get his chest scar

No, Luffy doesn't get married in the manga. His focus is mainly on adventure and becoming the Pirate King.

Todoroki got his scar because of his father's cruel actions. His father, Endeavor, deliberately caused the scar to try and shape his son's powers.

In some fanfictions, Naruto might get the scar on his eye during a particularly intense battle with a powerful enemy. Maybe it was a close encounter with a rogue ninja's weapon that managed to leave a mark on his eye area.

Hermione might be the one. With her extensive research skills and vast knowledge of magic, she could have stumbled upon a way to remove the scar. She was always determined to help Harry, and this would be just another of her great contributions.

Luffy gets Gear 5 in chapter 1044. This chapter is a major turning point in the story with his new power-up.

Luffy embarks on a challenging quest and uses his wits and strength to rescue Chopper. There are many battles and obstacles along the way.

Well, Bolsa could get many of his stories from various sources. It might be from old books, or from listening to others' tales. Sometimes, inspiration just strikes from everyday life situations too.

Well, his crewmates might be a bit more protective of him at first. They're used to Luffy being a tough guy, but now he looks like a girl. Zoro might be a bit more hesitant to let him get into fights right away. Nami could be more motherly, trying to make sure he's dressed appropriately. Usopp might crack more jokes about Luffy's new look. Sanji, on the other hand, would probably be over the moon and constantly trying to cook special things for 'her'.

Well, it definitely slows him down. He can't push himself as hard as he usually does. His stamina is lower, so he might not be able to complete his normal training routines.

Yes, he does. Luffy's devil fruit awakening occurs in a significant storyline within the manga.
