How did Luffy get the scar on his chest?


There's a debate going on how Luffy got the scar on his chest but I recently
seen episode 223 where Zoro and Luffy we're fighting and Zoro gave him that
scar. Then for what reason is there a debate on how he got his scar?




I think Luffy got the scar during Marineford War. It's on Vol. 59 Chapter 578
and Episode 487.

After his brother Ace died, Jinbe carried him and tried to escape to Akainu.
Jinbe jumps into the sea but finds the water below to be frozen. Akainu
manages to strike Jinbe and harm Luffy at the same time. Jinbe apologizes to
Luffy for letting him get injured.

It can be seen in this image that Luffy's chest is burning after Akainu's
punch past through Jinbe's body.

[One Piece Wiki](http://onepiece.wikia.com/wiki/Monkey_D._Luffy) also did
mention how Luffy got the X-Mark after the time skip
