Luffy was pissed when he saw his flag in flames after the straw hats docked on an island. Luffy caught a glimpse of who burned it. The man who burned the flag ran up the hill and into the forest, of course luffy chased after. The crew saw luffy run off and zoro said, "oi!? Where are you go-, but was then interrupted by the sizzling flag's burns. Zoro knew then where luffy was going. The crew went after luffy. Usopp stayed behind because of his, " I can't enter that island or I'll die," disease. After hours of chasing the man, luffy finally pinned him right where he wanted him. Robin bloomed an eye on a nearby tree and told the crew where luffy was. When the crew got there chopper noticed luffy right away. Luffy was on the ground! Chopper said, "LUFFY!" His left leg bones were shattered but there was still blood flow. Zoro and sanji helped carry the broken captain to the ship. Luffy was unconscious until he felt a sizzling pain. Luffy darted about a mile scaring the crap out of chopper. Luffy growled like a wild animal! Chopper said, "Luffy?" In a consernative voice. Chopper was approaching luffy when he realized luffy was backing up into a corner. Luffy was growling even more tense than before. Chopper left the room after luffy bit him! After chopper left luffy calmed down and fell asleep on the floor. Meanwhile chopper told the crew how luffy was acting, but they soon heard screaming and yelling. Finally they heard one of his best attacks. Gomu Gomu no Gatling! Luffy yelled then breaking the wall. He tried to jump off the ship! Thankfully franky caught him. Luffy was fighting franky's grip saying LET ME GO! I NEED TO KILL HIM! The crew had never heard luffy threat to kill. Luffy finally broke free from franky's grip. He ran around the sunny like a wild beast. The crew was trying to catch him. Chopper realized his leg had healed. Zoro said, "Luffy this isn't you! Come here." Luffy came to his senses for a few minutes and said, "what's going on?" The crew in shock realized luffy fought uncausiously. But when luffy heard the sizzling of the Fire sanji was cooking on, he fell unconscious and started fighting again. The crew decided to sea prism cuff him to his bed once he fell asleep. Luffy awoke the next morning to see him cuffed to the bed. Luffy asked zoro what was going on? Zoro explained. Luffy said, "oh..." "Well I'm back so can you unchain me?" Zoro thought a minute then said, okay. The crew saw Luffy smiling and happy again, and questioned zoro later. Robin said, "he shouldn't see or hear fire, because it triggers him." The crew agreed. Luffy was happy to be able to walk outside.
