I'm not the best at writing fight scenes, but I hope this one is satisfactory! Enjoy~

Dark Luffy walked along the wall of a city he'd had fun messing with. He left a few people alive, because why not? He had raided a market and was feasting on all of their food. He was always hungry with how much energy it even took for him to function in Luffy's body, which was sadly, failing.

Luffy's body was constantly bruised from the force of the quake quake fruit when he used it, even with the pheonyx powers to heal. He was also constantly hungry without being able to find a lot of food or water, and was becoming malnourished. He also couldn't sleep properly for some reason.

But this didn't deter Dark Luffy from going about with his business since he was numb a lot of the time, and carried a pack of medical supplies with him at all times after getting a forced check up from a human doctor. Of course he then murdered him when he didn't like the results and took as much medication as he could with him.

And he was bummed, since, when Luffy's body completely failed, no matter if Dark Luffy was able to escape, he wouldn't have the convenient ab ab fruit. Maybe he'd find it somewhere else but he had no idea how to change bodies with someone else.

It had been a pain to hide this ability from Luffy, but once the boy gave Dark Luffy full control, he could use them whenever he liked. And now, with him finally mastering Whitebeard's power, along with the ability to use any Devil Fruit, he was now the strongest person in the world. And he loved the feeling.

He looked to the side of the wall as he was walking to the next market to clean out those shelves as well, he saw a few men. They each looked strange in their own way. Ugly, as well. There was a tan, fat one with a lot of chest hair and an ugly smile. And he was smiling at Luffy.

The others with him stood next to him, all looking very uncomfortable, since Dark Luffy gave off the haki at all moments. Even the horse one of them was laying on looked afraid.

"You're really creepy, Demon Angel. No wonder there's no photo of you," the man said, and laughed a laugh just as ugly as he was.

"Oh?" Dark Luffy asked threateningly. He grinned at them and his black irises spread to the rest of his eyes. No longer were there any whites. Just black orbs as he stared at them. They all flinched, including the brave man who spoke to him disrespectfully.

"And who might you be, ugly, fat man?" Dark Luffy asked as he walked closer to them. His haki became more terrible the closer he got to them.

"T-Teach, we should go," a man with a large gun said nervously.

"Teach? As in the Teach who betrayed the Whitebeard pirates?" Luffy asked as he stood a couple yards away from them, his wings moving around in excitement at the fight he was about to have. "You have a powerful Devil Fruit, don't you?"

He laughed loudly. "Yeah, I almost killed Thatch to get the dark dark fruit.," Teach bragged.

"Oh, we have that in common. I tried to kill him as well. Why don't you show me your Devil Fruit?" Dark Luffy asked conversationally, but still very deadly.

"Why, you want to take my power, too?" Teach asked dangerously. Luffy answered with a "Yup".

"Then I'd have all my powers from the Whitebeard crew. A little collection," Dark Luffy said with a smirk. Teach told his friends to get away so he didn't end up killing them. Luffy grinned in excitement at a real fight, if this guy wasn't lying to him.

Teach attacked first, throwing what Luffy would have called "shadow goo" at the angel. Dark Luffy easily jumped high into the air. He hadn't really fought battles before, but he could feel instincts on how to do this.

He broke off a shingle from the roof he landed on and threw it into the darkness, watching it be completely absorbed, and not coming out the bottom. That stuff could swallow Dark Luffy, and then who knows what would happen once inside. He had to stay away from it, especially because he can feel a little pull towards the black mass, which had begun to spread around the building, making the whole structure sink. He'd be screwed if he couldn't fly, and dance away from the streams of black hurled towards him.

He decided it was his turn to play offense and got up close to the fat man, turning his arm into diamond and punching him hard in the face. The diamond don't break the skin like it should have, but it still sent Teach reeling from pain. When Luffy flew closer to burn him to a crisp by grabbing him and lighting himself on fire, that didn't work. The fire didn't come out.

Luffy jumped away and flew a few yards to another building. "That's an interesting power. Tell me how it works?" Luffy asked pleasantly. Besides, he already had this power just from touching the man. This was a little tutorial.

"Darkness swallows everything, and can destroy anything!" Teach bragged. "I can change gravity, and PULL YOU IN! I can also cancel out those nice Devil Fruit powers you got there," he shouted as Luffy started to fly towards him. But when he got too close for comfort, he stomped Teach in the face and propelled himself up, directing his hands down at the sime time to crack the air and fracture the ground the man was standing on. Dark Luffy wasnt going to have his powers cancelled out by this guy, no matter how. He needed to be careful when touching him.

Teach fell off balance and the power disappeared. But this made him mad. A six year old kid was putting up a good fight against him. Dark Luffy was becoming cocky. "You're not a very good teacher. I don't know how to work it… Like this?" Dark Luffy questioned as he released darkness from him as well, though it wasn't controlled well. Teach scowled, looking furious.

"I'm going to steal your power, you little shit!" he roared. Dark Luffy fake yawned.

"What would happen if I swallowed your friends into my own darkness? Would they die?"

Teach grew angrier, telling his group to get away from them. But Dark Luffy said, "Ah ah ah! Running from an enemy you're not even fighting is disgraceful," as he flew towards them. He turned his leg into diamond and kicked the horse's face and brought it down, going after the strange looking rider and pummeling his head into the ground. Then he danced away and back into the air as the other living people crowded around his body.

Teach looked shocked as he saw how brutally Dark Luffy killed his friend. Then he grew livid as the evil angel laughed. "That's too bad. Needless baggage isn't desired. I've done you a favor. You shouldn't have picked a fight with me, but a new power is always welcomed."

One of the men on the ground turned around and shot Dark Luffy. But of course, with Dark Luffy also having a logia's power, the bullets went right through him. The boy looked back at Teach, who was livid that he was losing to a child. He covered everything in the blackness, even up into the air.

Dark Luffy slammed his hands into the air and made a quake big enough to rattle the island. Teach fell backwards, now that there was nothing to hold onto or hide behind since everything had been swallowed by his darkness.

He had a feeling it wouldn't work, but the angel used his fire power to make a huge orb of concentrated flames above his head and threw it at his opponent. Teach screamed, yelling that it was hot, but nothing too bad happened to him.

So Dark Luffy tried something else. He changed into the pheonyx form and flew at the human fast and grabbed his shoulders with his talons, lifting Teach high into the air and then dropped him from above. He shouted in fear as he fell, but landed perfectly fine in his darkness, popping right back out. He was breathing heavily now.

Facing against someone who now had five Devil Fruit powers was proving difficult. He hated how well this punk had mastered the abilities after only having them for a few months.

But it was Luffy's body that compromised the fight just like that. His wings, which he'd made back into normal, cramped, and he fell. He had the dignity to not scream like an idiot, since it didn't hurt to hit the ground with him being a logia. He landed in Teach's darkness. But then, something no one had predicted to happen, not even the evil creature himself, happened.

Luffy didn't sink into the darkness. Instead, he fell forward, unconscious, as Dark Luffy was drained from him and into the pit of black. His wings went back to being white, and he was completely knocked out. It would have been a total victory if it werent for the fact that Dark Luffy was now in Teach.

"Wh... what the hell?" Dark Teach questioned in a deep voice. He looked to Luffy's small form and widened his eyes. Then he began to laugh, no longer a sadistic little giggle. No, it was the laugh of a grown man.

"Well, I would have needed to get a new body somehow anyway, since you're dying," Dark Teach said to the prone form of Luffy. He was bummed he lost Luffy's Devil Fruit, but it would've happened anyway, and now he at least had a strong Devil Fruit in this new body.

The darkness disappeared and the ground was flattened in a wide arena-like shape. He didn't even notice Luffy was gone as he walked to Teach's friends.

"I've never used a gun before… Why don't I try it out?" and he shot one of the cowering pirates in the head. The others gasped.

"Why, Teach?!" one of the remaining humans said. Dark Teach twirled the gun in his big hand.

"Well, you're slow, aren't you? Your friend Teach is gone, and he might have liked you, but I'm not too good with company," and he shot two others. "Oh, there's a woman on this crew! That's surprising. Most crews don't have women. Good job for being diverse, I guess." And he shot her in each eye.

The others were frozen in fear, except one, who had had a cigar in the beginning. He foolishly ran after Teach, but Dark Teach just created the darkness below him. "I wonder what would happen if…" he said and moved his hands above his head. The darkness formed above him from a very high height and the man fell out, landing on the ground with a sickening crack, his neck snapped. "Wow, this power is pretty cool."

He murdered the other few members, looking at their pile of dead bodies before walking away. He didn't see Luffy anymore, but he didn't care about his old body. He'd make a name for himself in this body. Hopefully it'd hold up better than Luffy's .

"So long, Luffy," and he walked away.
