Previously with Luffy and Hulk…

Hulk flew in the air and away from the Avengers tower, luckily landing in the middle of an abandoned park. The almost full moon lit up the trees and the few lamp posts scattered around provided ample enough light for anyone to observe the momentous fight between the strongest man and an unknown. To anybody watching, the unknown man in a straw hat was just about to be put through the biggest beat down of his life and the chances of him escaping alive were slim. They would soon find out it was true, but not for the man with a Cheshire Cat smile on his face, but for the man they previously assumed was invincible.

Luffy stared down his opponent from underneath his favorite hat, he didn't look that bad, just green like vegetables. Luffy inwardly chuckled, now he'll have fought two vegetables.

During Luffy's internal dialogue on vegetables, Hulk stared at his opponent in a strange lapse of intelligence and restraint. Something about this scrawny man screamed to Hulk to run away as fast as possible and never look back. However the split second lapse of restraint was gone and he instead roared loudly and began to ran at the man who had made him so angry.

Using a bit of Observation Haki to keep a figurative eye on the Hulk while Luffy was thinking, allowed him to sense the Hull running at him. Though, with the loud roar the Observation Haki probably wasn't really needed. He spun around to face the large green rage monster that ran at him and a large smile crossed his face. Luffy went into second gear and ran at the Hulk.

As the two monstrous strengths met, Hulk made the first move and aimed a punch at the tiny annoying man. Luffy seeing the punch from a mile away jumped up onto Hulk's arm and used that to give him a boost up. Luffy flew into the air and bit his thumb, inflating his entire arm into a ridiculously large size, almost as large as Hulk's arm.

Now into third gear, Luffy shouted but it could not be heard over the angry roars of the Hulk. Hulk roared louder than ever, angry that his first punch didn't hit the man at all. Hulk angrily jumped into the air, now level with Luffy. Instead of the fear or surprise that was expected, Luffy's constant smile became even bigger as he punched the Hulk in his midsection, propelling the Hulk back down and creating a crater.

Luffy fell back to the ground and was surprised when suddenly the Hulk's arm shot out of the crater and grabbed Luffy by the neck. In his surprise, Luffy fell out of second gear and began to try to pry off the giant green fingers from his throat. It didn't really hurt, because the guy wasn't using Haki for some reason. That confused Luffy for a second, but he immediately discarded that thought and instead focused on the fight.

Right when Luffy started to pry of the Hulk's fingers, he was suddenly thrown into the air and punched in the gut. The force of the blow sent Luffy through a nearby building and stopping half way through another. Once again Luffy wasn't harmed,besides a few small cuts from glass, as there was no Haki in the punch that he had received. Luffy frowned this wasn't any fun if the other guy didn't even know how to use Haki. He would just have to end this fight quickly so he could go and find Torao.

Luffy slowly stood up as rubble and debris fell off of him, he clenched his fists and spread his feet apart to give himself better balance. He could hear the Hulk crashing through the building he had previously been punched through, so all he had to do now was wait.

The Hulk burst through the wall in an explosion of anger and rubble. Instead of being met by fear, or fists flying like he was usually met with, the Hulk wasn't met with anything. The scrawny man stood before him, dusty and covered in small scratches that had stopped bleeding, apparently waiting for him. This unusual display of calmness, almost stopped Hulk in his tracks, but he was too angry for that, so he charged.

However, as the Hulk was charging at Luffy, an overpowering feeling of fear overwhelmed the Hulk's senses. The flood of emotion, other than anger, pushed the Hulk temporarily down to his knees. The effects of the Conqueror's Haki did not last long, but it gave Luffy just enough time.

The Hulk angrily punched the ground and slowly began to push away the fear and replace it with anger. He slowly slammed one foot into the ground and then the other. Now he was finally standing, and angrier than ever before. No one had brought the Hulk to his knees without even touching him. Hulk was supposed to be the strongest there was, but now this puny guy forced him to his knees by just looking at him. That made Hulk very, very angry. Right when Hulk began to charge a loud voice echoed, "Gear Fourth!"

Luffy's body was now laughingly disproportionate, his upper half and arms were gigantic compared to his extremely smaller lower body. Steam poured off of his body that had somehow acquired black swirls that covered his chest and completely covered his arms and legs. His hair stuck up strangely and made home look slightly crazy with large black circles around his eyes. However crazy and weird he looked though, no one was laughing.

Luffy bounced as the Hulk charged closer to him and when the Hulk came to about a hundred feet away from him, Luffy retracted his feet inside his legs and began to fly towards the Hulk. With his brow furrowed in anger and concentration, Luffy slowly brought his clenched fist inside his arm. When it was sufficiently pulled back, Luffy narrowed his eyes as he waited for the Hulk to get closer. A second before collision, Luffy shouted, "Kong Gun" and released his fist.

The shock of the impact shattered any glass within a half mile radius and set of hundreds of car alarms. The punch caught the Hulk right in the chest and caused all of the breath the Hulk had to be knocked out. Due to the angle of the punch the Hulk went into the ground slightly before continuing backwards, causing a large trench to be dug that became progressively deeper. He flew back through the building again and continued going through the park and he did not stop until he had gone several hundred feet, crashing through the foundations of a few more smaller buildings and ending up half a mile in the ground.

The combination of the previous Haki attack and then being punched, successfully knocked the Hulk out. Slowly he began to morph back into the significantly less threatening Dr. Bruce Banner. Banner stayed in the large trench, unconscious until his teammates found him and retrieved him.

When the giant green creature flew out of sight and Luffy could sense him unconscious, he finally went out of Fourth Gear. Luffy looked up at the sky and frowned as he couldn't see one star, only the large white moon shining down on the suddenly quiet street. Luffy stumbled forward, he had to go find Torao and his nakama now. Before he had gotten very far, Luffy collapsed at the end of an alleyway and fell asleep, snoring occasionally about meat.

Back at Avengers tower

Despite the initial confusion of switching bodies, the Avengers managed to calm down enough to figure out who had switched with who. On a whiteboard in a conference room was written:

Tony…...Natasha

Natasha...Steve

Steve…...Clint

Clint…...Tony

Everyone was silent as they attempted to get used to their new bodies and some pouting slightly at their recent defeat, though they would never admit it.

When the silence began to be almost unbearable, Tony burst into the room, with a small cardboard box. He slammed it onto the table and pouted, the expression strange on the normally expressionless Widow's face.

"Alright no one ask me what's in the box! It's not like I care or anything!"

Everyone just looked at Tony and glared slightly, the last thing they needed was Tony's boundless energy and sarcasm. However they knew he wouldn't shut up so Steve sighed and asked, "Tony, what's in the box?"

"Now that's a very good question! I decided since we keep on forgetting who's who that we need to have a way so we don't mix each other up."

Knowing it was probably pointless to stop Tony when he got like this, the Avengers just sat there and looked at Tony, waiting for him to continue on with his ramble, however they tuned him out until the end. For the most part they found if they did that, they were less confused and still got all of the information they needed.

"...so I found these in one of the storage rooms."

Tony finally getting to the point, opened up the cardboard box, revealing a few hundred name tag stickers. He grabbed out a handful of stickers and gave one to each of his teammates. Seeing the logic in the name tag idea, the avengers filled out their real names and slapped the tags on. Suddenly an indignant yelp was heard in the room and a loud thud.

" I warned you about touching my chest didn't I Tony?"

Everyone was quiet as Natasha began to beat the crap out of Tony with the incredible strength of Captain America. She was only holding back slightly as she didn't want to permanently damage her body. This was going to be a long day for everyone.

Hope you guys liked the chapter. In one of the reviews, someone was wondering why Law had such limited energy.

Both Luffy and Law are going to be tired and their powers more downplayed. Traveling across dimensions and especially through a portal has taken a toll on both of them. They will be exhausted temporarily as it won't be much of a story if the Avenger's get their asses handed to them.

Remember to review!
