So this is my special April Fool's Day story that I have been planning forever. I hope you all enjoy it.

~A Plan is Hatched~

Sabo stretched as he walked onto the deck of the Thousand Sunny, smiling as he watched the straw-hats interact. It was good to see his brother had such a caring and devoted crew. Sabo glanced at his hand, remembering the first time the flames emerged, did Ace ever get to see Luffy's crew?

"Sabo?"

Sabo turned at the familiar voice to face the archeologist. "Yeah?"

"You okay?"

Sabo nodded. "I was just wondering if Ace got to see this crew."

Robin smiled sadly. "He got to meet everyone except for Franky, Brook, and myself."

Sabo turned to watch the group again, everyone seemed particularly happy. "Why's everyone so excited?"

Robin chuckled. "In a few days it'll be the first birthday we get to celebrate as a crew again."

"Really?"

Robin nodded. "April 1st is Usopp's birthday."

"April 1st?" Sabo looked at the sky in thought.

"April fool's day, it fits Usopp somewhat." Robin laughed.

"We used to play a lot of tricks on people on that day," Sabo stated as he looked at the raven next to him.

Robin chuckled. "I'm not surprised."

Sabo stared at where Luffy was playing with Chopper and Usopp, deep in thought. He could feel Robin's eyes watching him carefully. Sabo turned his gaze over the sea after a while.

"I'd love to play one last amazing trick."

"Not on us I hope." Robin watched the chief.

Sabo shook his head. "No."

Robin watched him. "Who then?"

Sabo laughed. "If I could the world."

Robin watched him still, her eyes trailing to the blonde's hands. She laughed drawing his attention back to her at the sudden sound. Sabo watched her in confusion as she walked over to him, bringing a hand to his hair. He was used to her messing with his hair, when she had grown to trust him during her time in the Revolution she had cut their unit's hair when she found it unruly.

"I wonder." She mused before turning away from Sabo.

"What?"

Robin ignored Sabo as she looked at Usopp. "Usopp, I need your help."

The sniper stopped what he was doing, Luffy and Chopper looking disappointed. "What?"

"Just come here."

Usopp obeyed and came to stand next to the older woman, she whispered in his ear, pointing to Sabo occasionally. Usopp blinked and shook his head as he almost yelled, before Robin quieted his protests. Sabo blinked wondering why he was their point of discussion, the whole deck seemed to have quieted down as well, watching the trio.

"I guess." Usopp looked nervous and unsure.

Robin smiled reassuringly. "It'll be fine."

"What are you two plotting?" Sabo asked, watching Robin, knowing her to be the one truly plotting.

"An April fool's day joke." Robin gave the chief an innocent look.

"On?" Sabo didn't believe her innocence for a second.

"The world."

Before anyone could respond Robin began leading Sabo inside, Usopp following after, looking a bit nervous still. Sabo blinked, but knew not to refuse the woman's actions, she'd force him inside one way or another. He was dragged into Robin and Nami's room, and the raven put a do not disturb sign on the door.

"Usopp go get that black dye you guys bought for that prank."

Usopp sputtered. "You knew about that?"

"Yes, and if you did it Franky would be pissed."

Usopp nodded. "Right. Be right back."

Sabo watched the sniper leave, and looked at Robin as she pulled him towards a chair. He sat in it after he took off his jacket and hat, Robin tossing them onto the bed. She looked him over before telling him to remove his shirt and cravat as well. Sabo did as told, knowing not to argue with the woman.

It didn't take long for Usopp to return, still looking apprehensive at the plan. Sabo looked at him, hoping the youth would tell him what was going on. Usopp only watched Robin, as she finished gathering what else they would need. Sabo felt a towel wrap around his shoulders, and blinked at that, wondering what was going on.

"The marines will kill us."

Robin laughed. "They'd have to catch us first."

"The Whitebeards will kill us."

Robin shook her head as she walked in front of Sabo, examining his hair. "No they won't."

"You sure?"

"They'll be helping us." Robin kept pulling his hair lightly, examining the length.

"What are you two plotting?" Sabo questioned.

"A joke." Robin moved around him. "Does Koala know how to contact the Whitebeards?"

Sabo rolled his eyes. "We got their contact when we visited the grave."

Robin moved away from Sabo. "Usopp go and grab Koala, when you return we can begin working on his hair."

"My hair?" Sabo blinked.

Robin laughed. "Yes."

Usopp didn't argue and left immediately to do as he was told by his crew-mate. Robin set to work brushing out Sabo's hair. She hummed softly, and it helped Sabo's nerves somewhat, but he was still confused. He jumped as he felt a cold gel like substance being spread around his hair line and ears and neck. Robin laughed as she felt him jump but continued doing what it was she was doing.

"I'm coating your skin so that the dye comes off of it easier." She assured him.

"Why?"

"Do you want raven colored skin?" Robin asked.

Sabo didn't respond, knowing that wasn't what Robin wanted anyways. He sat there patiently as she coated the areas, and by the time she finished, Usopp returned. Robin nodded to Koala, who looked confused as she watched the Raven woman who stood mixing the dye up for Usopp. After a few minutes of Robin mixing, the sniper put on gloves as he stood behind Sabo, Robin placing the needed tools next to him.

Robin walked past the seated blonde to the other girl. "I need your snail and the number for the Whitebeard pirates."

"Why? What's going on?"

Robin smiled reassuringly at the girl. "We're planning an April Fool's day joke."

"What kind of joke?"

"You'll see." Robin took the info and went to stand outside the room to make her call so those inside wouldn't hear.

"Sabo?" Koala questioned looking at the blonde.

Sabo didn't budge as Usopp worked on his hair. "I don't know."

"Usopp?"

Usopp shook his head as he concentrated. "Robin told me not to tell."

Koala sighed. "Is this going to get us into trouble?"

Usopp bit his lip. "Yes."

Robin returned a while later from her call, and handed the snail back to Koala. She then began rummaging through the book she had brought back with her. Usopp was finishing up the dying process, Sabo complaining about the burning sensation he felt in his scalp. Usopp finally finished and instructed Sabo not to do anything to his hair, that they'd wash it out when Robin said to.

Usopp sat on the floor in front of the blonde, to watch him to make sure he didn't mess up his work. Koala joined Robin on the bed, and Sabo watched as she flipped through what looked to be wanted posters. She kept searching until she reached what she was looking for and showed it to Koala. The girl gasped and looked between Sabo and the wanted poster, shaking her head in shock.

"No."

"Yes." Robin nodded.

"This is suicide."

"It'll be fine." Robin assured.

"You're going to get him killed."

Robin raised an eyebrow. "He's a leader of the Revolutionary Army, this can't be the worst thing that he's done."

"Robin." Koala pleaded.

"Too late, plans already in motion."

Koala groaned. "We're so dead. Dragon's going to kill us, if the marines don't first."

"What is going on?" Sabo questioned, extremely worried now at his partner's reaction.

"You'll find out once your hair is done."

They sat there in silence after a while, Koala pacing as she muttered in agony to herself, Robin looking over the various wanted posters. The one she had pulled out, being kept from Sabo's sight so he wouldn't know. Usopp sat tinkering with something on the ground, eyes moving to Sabo to make sure the blonde didn't do anything he wasn't supposed to. Sabo just sat there, extremely bored and uncomfortable, waiting for the time to tick by.

It felt like forever till Robin declared they could wash the dye out. He was dragged to the bathroom, Robin making sure no one could see him as he was dragged outside of the girl's room. When they arrived at the shower, he felt his hair being pulled into a shower cap and towel around his head before Robin began running a wet rag around his skin that she had coated, to remove the dye from the skin.

After she was done she then took the stuff off his hair before dragging him to the shower. He set down on the stool she brought out, and leaned back as directed. He felt the water begin cascading over his hair and felt Robin's hands running through his hair to get all of the dye out. Once the excess dye was out he was sat up again and Robin told them to wait a bit before they thoroughly wash his hair with shampoo and conditioner.

Sabo was easily growing annoyed at all the secrets but played along with it as he joined the three in casual conversation. Robin making sure nothing of her planned leaked out on accident from the two. After an hour passed Robin rinsed out his hair, shampooing it and conditioning it. Once she was satisfied with the job she allowed him to stand, and Usopp helped him dry his hair thoroughly.

It wasn't long till they were dragging him back to Robin's room, the others on the ship having their eyes covered once again. Usopp began styling his hair, straightening his locks and making them a bit wavy. Sabo sat there not complaining, knowing it was too late now. Once Usopp finished he stepped back to stand next to Koala to admire the work.

Robin stood with them and held up the wanted poster. The three stared at the poster as it blocked Sabo's face from them. They took in the hair of the raven on the poster, before Robin dropped her arm to the side to reveal Sabo. Koala blinked as she stared at her partner, Usopp sputtering, while Robin simply smiled and gave a little chuckle.

"What did you guys do?" Sabo questioned at their expressions.

Robin pulled him off the chair and brought him to the mirror to face it. She then held up the wanted poster next to him so he could examine his hair and the person's on the wanted poster. He stared in shock as he found his hair styled and the same color as his older brother's hair. He swallowed, this was the first time he had ever seen his hair black before, he really did look like he could be Luffy and Ace's brother by birth.

"What do you think?" Robin asked.

"Robin. This." Sabo couldn't find the words he wanted to say.

"This is our prank."

Sabo blinked. "Prank?"

"Welcome back from the dead, Portgas D. Ace." Robin chuckled.

Sabo could only stare at his new image, in shock, still trying to figure out what had just happened. He now knew why Koala and Usopp were freaking out, yet at the same time he felt excitement grow, he couldn't wait to see what else the archeologist had planned for this prank. He smirked, finding it easy to slip into Ace's habits, he had known the raven so well, this would be easy.

~End ch. 1~

There will be more chapters throughout the day! After all Sabo hasn't fully transformed into Ace yet. The Whitebeards will be appearing next chapter, or at least a few of them will be.
