How is Natsu Dragneel of fairy tail similar to Monkey D Luffy of One piece?

Answer 1

Natsu Dragneel and Monkey D. Luffy are very similar in many ways some people might say they look similar in art which is why it's commonly mistaken that Fairy tail was written by the same creator of One piece but that is not the case and there is no rivalry between any of the two either.

Both Natsu and Luffy were raised by someone other than their own biological parent, Both of their father like has the name Dragon, Natsu was raised by an actual Dragon while as Luffy's father's name is Dragon. Both Natsu and Luffy has a key item given to them by the person that they wished to meet again one day, Natsu was given a scarf by Igneel and Luffy was given a Straw Hat by shanks. Both also have a distinct scar near were their key items are. A scar is on luffy's head where he's hat is worn and A scar is on Natsu's neck where his scarf is worn both scars are caused by themselves. Both Natsu and Luffy are the founder of their teams. Natsu is immune to fire and Luffy is immune to Lightning but Lightning can hurt Natsu and Fire can Hurt Luffy. Both has a member on their team that cares a whole lot about money that being Lucy and Nami. Both has a bad reputation with the Government and both has infiltrated the Government headquarters to save a friend, Both has the same impulsive nature and Isn't afraid to challenge stronger opponents and sacrifice themselves for their friends and crew.

The two also has a lot of differences such as Natsu doesn't have any known living relative unlike Luffy. Natsu can swim but can't stand transportation while as Luffy can stand any transportation but he can't swim. Natsu is a member of a guild and Luffy is a member of a Pirate Crew, Luffy wants to be the King of the Pirates and Natsu just simply wants to get stronger and Become an S-class mage. Luffy's abilities came from a devil fruit while As natsu's Ancient magic was taught to him. Natsu can run out of magic energy while Luffy doesn't unless he is exposed to the ocean or sea. Luffy has the uncanny ability to be smack down in the center of trouble without provoking it himself unlike Natsu who often Gets in to trouble on his own accord. Luffy is a wanted person while as Natsu is a free mage who is under closed watch for his ability to often destroy things unconsciously.

The list can go on and on for as much as anyone likes and other characters have are quite similar too such As Lucy and Nami, Shanks and Gildarts, Gray and Natsu's relationship is similar to Zoro and Sanji's. Chopper and Happy are somewhat the same, so is Sanji and Loke because they're both ladies man.
