Forum:Luffy's scar

So I've been looking over some comments and a lot of people are syaing that luffy's new scar probably came from training with rayleigh, but when jimbei was trying to escape with luffy after he passed out they were both badly burned by akainu...and in the manga the smoke on luffy was on his chest...so its not really a new scar just one we hadn't seen since the war because he was covered in bandages up until the recent manga releases
