So this is a darkish Oneshot about the revenge of a woman that Blackbeard crossed. Because I feel vindictive tonight and you really don't need to be super powerful to kill a person even if it looks like that in the OP Fandom. Mentions of rape and murder.

Oneshot

The pirates stared at the barely 5,5 tall young woman that climbed onto the deck. She had slightly curly medium long hair and brown eyes and tanned skin. Nothing especially exotic but beautiful in a girl next door way. She looked average in every way, from her sensible travel clothes to her hair cut and the worn shoes.

Her smile had something brittle and horrible to it and Marco was honestly not sure if he wanted to know while she smiled like this.

"You said you had something for us." Marco finally said when pops didn't say anything to their guest.

The girl nodded and placed the box she had been carrying in a duffel bag in front of her.

"I think out of all the people in world you probably deserve his head and the fruit the most."

Marco relaxed even more while the pirates around him tensed, or at least the more inexperienced tensed, they had not yet learned that tensed muscles made it harder to move in an instant.

"His head?" Marco prompted the strange woman in front of them, he didn't take her for a bounty hunter, or hell even a fighter but stranger things had happened.

"Marshall Teach's," she elaborated, her eyes looked dully at him and Marco had to suppress a shudder at her gaze.

"YOU? Killed him?" an incredulous voice asked from somewhere behind Marco.

The girl simply shrugged her shoulders.

"How the hell did you defeat him?" another asked from his right.

At this the face was pulled into a mirthless grin when she fixated the general direction from which the question came.

"I put a paralytic in his pie and the drowned him in twenty centimeter high water."

Outraged sounds came from around the deck.

"How could you." One of them shouted in disbelief, clearly horrified "Don't you have any honor?"

The woman's grin became even more horrible "He raped my best friend to death… in front of me, her husband and four year old daughter, both who were killed afterwards… so no, I wasn't feeling very honorable."

Somewhere behind him Marco heard retching and he himself wasn't feeling very well… there was nothing that he could say to that and he really didn't want to think about what she did NOT say about her ordeal.

"Well then I'm off." The woman said hollowly before she carefully placed the devil fruit that had started all of this on the wooden box that contained Teach's head and slowly walked back to the railing.

Marco looked up to pops who hadn't said anything throughout the whole time, his expression was carved out of stone and he was only watching the clearly traumatized and broken woman leave the Moby Dick. Nobody tried to stop her.
