DC's Legends of Tomorrow/Flash cross with HP. Enjoy.

It was the worst day of her life, finding out that she was going to be married to the human waste disposal Ronald Weasley. Don't get her wrong... Ron was fine in very small doses and when you had food handy to keep him quiet.

But marriage? She's sooner jump into the Amazon river with an open wound and starving piranhas than let that idiot touch her. So she managed to beg off the wedding for a month or two, just to have one last vacation as a free woman.

Thank god Hermione was out with the flu and couldn't explain the concept of a "bachelorette party" or that they only lasted a day or two...not an entire month.

And that was how Persephone Potter found herself in America, with no supervision and absolutely no reason to hold back. She had looked through the prenuptial contract that she had forced the Weasleys to accept if they wanted her to agree to this nonsense... and the only way out was if Ron refused to marry her. Regardless of how his mother felt about it.

Persephone entered a random dive bar that didn't ask stupid questions like age and the like so long as you paid up front.

She sat down and started making a rather sizable dent in the bar's liquor stock, paying for her drink first in case she passed out from her current drink. The bartender liked her immediately, for obvious reasons.

"Aren't you a little young to be getting that drunk?" drawled a voice to her left.

It was a man about her age, possibly a little older. He had a shaved head, or perhaps hair that was so short it could be mistaken for such and more intelligence than her "fiance" on a good day. There was a cold calculating side to him that she could immediately appreciate.

"I'm being forced to marry a human waste disposal with a smothering mother that has for some reason decided that we make the perfect couple despite the fact that he has absolutely no concept of loyalty. Oh, and if he does somehow impregnate me I guarantee you he will be liberated of his balls long before the due date. Thank god that woman has no idea what a bachelorette party actually is, or that they don't last for two months in a foreign country."

The man snorted.

"Sounds like you need an example of what a good time actually is before you're stuck being bored for life," he drawled.

"Maybe I am. Why, you offering?" she shot back, more than drunk enough at this point that she could safely claim the hangover made her forget that she had gotten laid before the wedding.

Ron did not deserve that particular honor.

"You provide the booze, I'll provide the fun."

"Quick question, how drunk do you want to be before the night is properly over?"

His eyes glinted. He whispered something in her ear, and her smirk was rather wide.

They left in a car she later learned was stolen, with enough liquor between them to get both blackout drunk.

She woke up two days later with a raging hangover, two empty kegs of high proof liquor, and some fluid between her legs. What little she did remember had her grinning.

Definitely more fun than Ron would have been, if his stamina was anything to go by.

It wasn't until she was heading back to England that she realized maybe she might have been a bit quick to jump into bed with a stranger. Thankfully he hadn't had any diseases, but she was almost certainly experiencing morning sickness.

At least it would explain why she suddenly had nausea and her taste buds were off.

The moment she even suspected she had gotten knocked up (she confirmed it with a standard home pregnancy test when she realized she was late) she immediately holed herself up in the Black family manor, removed the floo access and gave Winky (one of the few elves to survive the war) permission to trap the hell out of the house. No way was she letting Molly Weasley anywhere near her while pregnant, let alone Granger.

The stalemate lasted all of four months, before she finally ran into Ron alone.

"I'll cut to the chase. I'll give you twenty thousand galleons to call off the wedding and one of the houses out of the country. In exchange you never contact me again," said Persephone flatly.

Ron blinked. This wasn't how he expected this to go.

"Give me thirty-five, and make it far enough that my mother won't find me without help."

"Thirty, and a new identity and shiny vault with your name only."

"Deal."

And that was the last she saw of Ron. To be fair, she never told him that the reason she handed him a house where he could make a name for himself away from England was right next to a relocated clan of vampires that hated men.

And she only knew that because she went and did a survey of all her properties to get away from people. She was the one who gave the clan clearance to live on the more or less abandoned property.

With her potential "husband" dealt with, now she only had to avoid the rest of Europe long enough to deliver her child (or children) and leave.

The last anyone saw of Persephone was when she was in a muggle hospital giving birth to twin sons.

Jack and Arctic Potter. She left England for greener pastures as soon as she was physically able, even if she was on painkillers at the time.

No way was she going to explain to any of the old crowd that the children were not Ron's in any shape or form. Especially after she had essentially given him a death sentence disguised as a bribe.

Time skip, six years later...

Jack looked at the playground with a critical eye. His brother Arc watched from his spot on the tree, not that the teachers noticed. They would have made him get down.

"What do you think?"

"I think I spy three bullies and a potential one in the making at three o'clock," said Arc.

"Yeah. This is going to be fun," said Jack grinning wickedly, before schooling his expression.

Their mother made a point to teach them how to spot the weak links. She made it clear she wouldn't tolerate bullying the weaker kids, those who were physically small and not very strong...but the bigger kids who thought their bulk, parents, or connections meant anything?

Yeah, those she could care less about.

Their mom was clear on how to spot bullies. And she taught them how to turn the tide against them. Make them the pariahs instead of the top dogs.

Jack's eyes were cold, Arc's were calculating. Alone, they were merely an underrated threat. Together they would display teamwork above and beyond any in their years.

They were kicked out of their last school because they had successfully dominated the place in a month, and one of the parents of the bullies actually complained that his son was being harassed by them.

Too bad for the parent, thanks to how thoroughly the twins had taken down his attempts to rule his class, he never rose from that spot.

"Arc, break it down for me. Lets review what we can see from here."

"Kids by the swings. Athletic, come from well established families, not particularly quick on the draw. Possible jocks. The ones by the trees. Pale, already reading slightly advanced books, potential nerds or bookworms. The group of girls by the stairs. Already in pretty dresses, have fake make up on and far too many hair accessories. Popular crowd. And last but not least, the bullies."

"Hmm. Seems like every time we go to a new school, the cliques always form within the first month or so," said Jack.

"And it only gets worse later," agreed Arc.

"Thank Loki we don't have to deal with them after school or attend stupid clubs," said Jack.

"And that mom is liberal enough with the family money to make our slip ups go away to a point," agreed Arc.

And by that he meant that their mother bribed the principals and teachers to keep their mouth shut about what really happened. At least, they assumed that was what happened.

It was actually cheaper and more fun to manipulate their memories and destroy the incriminating evidence after the fact. So long as they avoided juvie until they were old enough to enjoy the experience, they didn't need to know.

"Lets go break some idiots."

They were kicked out four months later. They were improving!

Time skip four years...

"Jack and Arthur Potter, I sentence you to six months in juvenile detention. Maybe that will straighten you two out once and for all," said the judge.

Arctic's eyebrow twitched.

"For the last time, my name isn't Arthur! It's Arctic! Why do people insist on mangling my name?!"

"Easy bro. You can take out your aggression on the obvious pedophiles in juvie."

"If someone calls me Arthur one more time..."

He hated being called Arthur. What other kid had a mom who was cool enough to call them Arctic rather than some lame ass name like Arthur or Nick? Hell, even his brother got his name off of something cool, like Jack Frost!

Inside the mess hall...

"Fresh meat! Fresh meat incoming!" cheered a teen who looked a little too burly to be intelligent.

Jack didn't even bother looking at him. They'd be going down soon enough.

Both ignored the cat calls of the older teens, and the looks that the guards gave them. They were just waiting to have a bit of fun.

And did they get it...in spades.

Jack was grinning like a maniac as he punched one boy out cold after another, with Arc keeping the idiots from taking him out from behind.

By the time the guards got things under control, twenty teens and three guards were in need of some serious medical care. To be fair, no one had expected Arctic to somehow turn a cheap plastic knife into such an effective weapon.

Needless to say both were chucked into solitary confinement for three days, and only given a minimum of water and food. Too bad it did nothing to break their spirits. Most twins had a sort of telepathy...magic took all that a step further.

And their mom had them learning magic after they successfully managed to punch their last gym teacher out with a single hit. He was rather overweight and the fat insulated him.

Arctic still knocked out his teeth. His breath was horrible.

When they got out, they discovered they had gained a new found respect from the senior boys and most of the younger ones. The slow witted ones just nodded in acknowledgment before going back to their grumbling.

That was how they met Rick.

"You two seem like you've had some training at this," he rumbled. He had a faint scent of smoke and other things that didn't like being lit on fire...like human hair.

"Our mom is awesome," Jack confided in him.

"Every time we get kicked out for taking over the class or fighting, she pays off the teachers so the next school has no idea what it's in for."

"Officially we move around a lot."

"...So how did you end up in juvie?"

"She didn't bother to hide the arrest records when she showed us how to hotwire a car, and she said the highest chance to get into here was to make the cop's lives hell while they were booking us," said Jack.

"Then she hired the worst lawyer she could find so we'd end up here."

"Doesn't sound very motherly to me," said Rick.

"Mom said we'd have more fun here than learning at school. Besides, if we get too bored she'll get a better lawyer or bust us out and move us to another state. So long as we pass the online exams she doesn't really care," said Jack.

"Though it was a pain in the ass finding a decent online college that would take us without a high school diploma," pouted Arctic.

Rick stared at them.

"And she doesn't mind the fighting?"

Both twins tilted their heads.

"Why would she? She's the one who taught us most of the dirty moves she picked up at bar fights and how to profile the weak links in every system."

Rick blinked, before a slow grin formed.

"So your mom beats you up a lot?"

"Why do all those stupid cops keep asking that when they see how we fight?" wondered Jack.

"No-Majs are idiots. Learn to live with it," said Arctic wisely.

The last two times they were arrested, and found out their mom taught them how to fight, the next question was always if she beat them up a lot.

It was really quite annoying.

"Remember the speech she gave us after that one overly-preppy teacher tried to convince us hitting people who pissed you off enough was wrong?" joked Arctic.

"How could I forget. We had it framed and gave it to her for Christmas remember?"

"Boys, I'm only going to explain this to you once. Humanity did not crawl out of the wilds using just their reasoning. Society was born in violence and keeps it's so called order with violence, though they like to pretend otherwise. The sheeple made of ordinary folk are kept safe because there are wolves and foxes willing to commit acts of great violence in their stead. I'm not going to lie to you and say violence is never the answer. Instead I'm going to train you so that when violence is the answer, you're not cowardly enough to hide behind some idiot adult and instead respond in kind. My sons will not be some weak-willed idiots who require others to do the job for them!"

Rick blinked in disbelief.

"She actually said that?"

"Word for word. Mom had to grow up with a bunch of weak willed morons who were too afraid of their own shadow to deal with some idiot terrorizing the community, leaving her to clean up their mess for them. Then she chose to leave after we were born as soon as the doctors said we were safe enough to travel with."

Rick grinned.

"I think I like this woman a lot. She sounds nicer than my mom," said Rick.

"Stick with us, and we might be able to bust you out once we get too bored to stick around."

Which didn't happen for seven full months (a record for them to stick around!) and their mother sending them what appeared to be sticks under a nothing-to-see-here charm.

Jack and Arc grinned, took out the captured wands their mother had sent them (she took them off some idiots from England) and pointed their new toys at the wand before loudly saying "BOMBARDA!"

Two blasts of magic later, and three hellions were on their way out of San Francisco's Juvenile Detention Facility and heading to a waiting car.

"Who's this?" asked their mom.

"This is Rick. He likes to set things on fire, especially people who annoy him," said the twins.

"Nice to meet you Rick. Think your parents will complain if you end up abducted by someone who has access to high powered explosives and likes to make big booms?"

"They signed off on all parental rights when I was thrown in a third time and sent me off to an orphanage. I haven't seen them in nearly five years," said Rick.

"In that case, hold on. When we get to a decently hidden campsite I'll teach you everything I know about blowing things up and getting away quick enough that they can't exactly blame you for it," she said cheerfully.

Rick turned to the twins and said with awe "Your mom is awesome!"
