The stories of Ace's adventures in many different universes and scenarios! AcexMarco is the main couple but sometimes Ace and Marco may just have a brotherly bond. It just depends what universe Ace is in. There are many different things going on such as MarineAce, HunterAce, modern Ace, etc, etc. So hope you have fun browsing!

Ace wakes up in his seventeen year old body after the events of Marineford, and promises that this time he will be strong enough to protect his family. In which the Spades are slowly driven to insanity by their Captain, and the Marines are not amused.

When Ace was just twelve, he was dragged to a different planet and labelled to be as a slave. Being adopted and pounded for many years, he is found by some bird-like male to become a pet, or slave, once more. Though, could him and this partner of his be different?

Ace had been making his way through the city to go to one of his favorite cafes. Well, that was until this hole ripped in the sky and some pirate fell out with the flaming bird guy following. Getting targeted, he is dragged into a different world with pirates and everything defying the reality he is used to. Will he make it home? Will he go back when the time comes? MarcoAce.

…to raise Marco's blood pressure, Ace's already ginormous appetite, and everything in between that needs raising. But then after over 20 years of sailing and facing off various enemies and marines, a baby would be no different than all of the adventures the ship has seen. [A/B/O fic, MPREG] [Sequel to 'The Heat']

Ace had been excited to reach Whitebeard's kingdom, being overwhelmed at his own that even his parents noticed. Being a phoenix of age came with the fact that the other phoenixes were trying to rub up on him, though he had his mind set on one. Marco had been his friend since the first time and now, he was courting him. Phoenix switching. Smut, Mpreg, Angst, Happy ending. OS.

Just a short smut that I had to get out of my head! Or in which Ace makes the mistake that no Whitebeard pirate knows not to make...making bets with Izo.

Ace is a firefighter and Marco a police officer and this is how they meet!...with a bit of smut! :3

About 100 years after the conclusion of the New Pirate Era, one of the ancient weapons goes off, destroying most of the world and its inhabitants. 20,000 years later, when it looks like mankind is about to make the same mistake twice, Marco has a decision to make this time around: to step in and potentially make things worse, or let mankind slowly but eventually perish.

A night in the Dark Forest was a bad idea. No, agreeing with Thatch's idea IS the bad idea. Now I am lost in the middle of this forest. How can I go home now?

At first Ace didn't like Marco but when he felt the blue flames he started to feel addicted to him. But Marco is trying his best not to be addicted to the kid's fire. Ace is his new brother and he has no right to touch him.

Ace had enjoyed the time that man left and now that he is back, new trouble brews. From the desire to burn the enemy to the new burning desire of lust, Ace can't catch a break. Will he fall into a trap? Can he protect his brothers? Were they really prepared for this all? MarcoAce! Rated M; cursing, lemons, and trauma! Multichappie! ((Semi-Hiatus))

It all started with a drunk confession. But there are more secrets where that one came from. One's past cannot be ignored forever. And love has never been easy. [Marco X Ace]

Being blind never stopped Ace from doing what he wanted. To him it was a weakness, but not much of a burden. Keeping his disability hidden Ace rose in the pirate world, catching the eye of the Whitebeard Pirates. How long can Ace keep himself from opening up and fully joining this crew? Especially with a first mate that is set on breaking down every wall Ace ever built. MarcoAce

Marco fulfills Ace's rare request of being "taken" over a pile of treasure like the mature pirates they are. Clue: It's a different type of taking. MarcoAce. Oneshot

"We're not dating," Marco said definitively. "That we're sharing a bed tonight is a total coincidence."

Ace knew he was inexperienced, but Marco was there to show him what to do. And honestly, it's not like he was complaining. He loved Marco either way, and Marco loved him back. Misc. smut stories for Marco and Ace.

Sequel to 'Both of Us'. Marco is up for the challenge to make Ace his official other lover while Luffy is away. Smut, MarcoAce, OneShot.

After having been appointed as the new 16th Division commander Izo found himself struggling with two things: How could he possibly live up to everyone's expectations and how on earth was he going to survive having these feelings for Thatch?

Side-fic for 'Control.' Ace might not be used to working as a sub, but it's not the role reversal that's the problem: it's the fact that his dom is somebody he's been attracted to for years, and if he makes a fool of himself now, he'll never live it down. Dom!Marco/Sub!Ace.

Rated K to M Will make more of this pairing even after the week! title says all prompt one Fire.

Marco and Ace have an unspoken arrangement, and neither of them wants to rock the boat. Written for the One Piece Reverse Bang. Warnings: Bondage, BDSM, Spanking, Sex Toys, Marking, Orgasm Denial, Dirty Talk, Explicit Sex

Marco is a 6 year old boy with a blue phoenix plushie. Ace is a 4 year old boy with a red phoenix plushie. What happens when these 2 meet? They fight over which phoenix is cooler, become friends, and as they grow up - fall in love? What about Aces cousin Law and a red haired boy? Or when Marcos best friend and neighbour, Kaku, is being bullied but is saved by a green haired boy?

Unfortunately for Marco, the nude model at his art class's session is too attractive for him to handle. When he introduces himself to him as Ace, Marco can hardly resist his invite for a coffee. Why does he seem familiar though? Is Ace hiding something behind those star-like freckles and beautiful eyes? opsecretvalentine gift for Miss Meira/missmissymeira on tumblr

Something unspeakable happens between the First and Second Division Commanders of the Whitebeard Pirates during a visit to a small island. They later find out it's because they have been cursed somehow. They mustn't touch or else... MarcoXAce

Being a werewolf doesn't mean turning into a hairy beast anymore. For Ace, there are a few side effects with the disease, and Marco helps him through a specific urge. PWP. Ace/Marco

Ace was furious… And jealous and hurt and all the things he wasn't supposed to be and it drove him mad. You see, Ace was in love with his best friend and exactly there laid the problem... One piece belongs to Oda... sadly -.-
