Double Legacy Sally Jackson Au

Okay. This has been my head Canon for like, years, imma try to explain the best I can.

So basically Sally is a 4th Generation legacy of the Norse God Loki (25%) and a 6th Generation Legacy of the Roman goddess Venus.

Making Percy not only 50% Greek sea demigod, but also:

20% Norse Trickster/lying/MISDIRECTION 5th gen

and 15% love/pretty as fuck Roman. 7th gen.

His Im/mortality blood split is more like 85/15.

Her parents (Percy's grandparents) died in that airplane crash when she was 5 because Sally's mom was a 3rd gen Loki and was unaware(cuz like apparently Norse demigods don't smell until AFTER they die) and Thor was all like, "heck no get the FUCK out of the sky" and Zappos hammered them to death.

(Percy has a Times 2 weakness to electric types. You think he's scared of ur lighting bolt? When he has to worry about a fucking lightning HAMMER? the answer is yes. To both. But like hammer>spear-bolt)

Sally found out about her heritage like maybe 2 months after her parents died(she inherited these cool norse pirate dagger/half-swords(I swear I can't remember what their called rn UGH), from HER great-grandparent. Percy's great-great grandparent ei: the Loki demigod. Loki gave them to her, and told her what's up.) and then she being the badass hardcore survivor she is, learned everything she ever could about Norse/roman(but also Greek) mythos by the time she's 12.

She meets Poseidon when she's 16.

Then Percy happens when she's 17 almost 18. And she learned from his father while she was carrying, that he would attract monsters.

Since she's related to Loki she has his whole "avoidance/dodge/misdirection can't be caught" thing. (As well as the shape shifting, but she can really only change her gender. But this is not relevant)

Sally, has been alone all her life, she is a SURVIVOR, so she buys an RV/tiny-home on wheels, and covers it absolutely completely buries it in a mix Norse and Egyptian magic-y misdirection runes to hide Percy's scent. She figures if she uses multiple mythos, it will be harder for Them to find her baby.

so there is no Gabe. Percy grows up even more of a mamas boy than canon.

She teaches Percy all about all the mythos, but like she does it in a very avoidance way that he knows NONE of their names like "the Greek sun god did this" or "the Roman sun god did that" and teaches him never to think their names "so they can't here you"

The changes in Percy's powers:

1: Since he's still Poseidon's kid but also now son of a legacy of the SHAPESHIFTER he can shapeshift, but only into a merperson, and only when he's wet. (Also he's genderfluid)

Sally teaches him to keep himself dry, he HATES it but understands that he needs to be sneaky, this first happens when he's like 7. And it doesn't happen during the full moon cuz like "the moon controls the tides" and what not. Yes, he is bioluminescent. Blueish/green aquamarine glowy mermaid fins!! His scales are either black or so dark indigo that they Look black.

2: Since he's a legacy of Venus, 7th gen notwithstanding cuz he has the 50% from the sea to make him stronger, he can do the charmspeaking, well... CharmSinging like a siren. When he was like 5 there was this really close call cuz when he sings one of two things happen. Either A: the default of "everyone in hearing range that isn't related to aphro/Venus is suddenly attracted to him, or b: people fall asleep. option a is the one that happened, he has to focus to get people to sleep. Sally is a smart cookie, she realized what was happening and decked the guy in the face before he could do anything to the baby 5 year old Percy. Sally then bans Percy from singing (at least around other ppl)

He HATES it. He loves to sing! but he understands enough to understand that sing around ppl is dangeours. This also happened when he was seven, but before the tail thing.

Sally, trying to hide Percy's heritage, and getting inspired from the Avatar the last airbender cartoon, trys to teach percy to only attack with "ice-bending" as to misdirect suspicions.

She tells him to "try and make the water stiff and cold"

He hates it. And how it feels "The sea doesn't like to be restricted" and what not, but like he trusts his mom, she's super cool and smart so he goes along with it, and OMG he gets cool water powers??? Like Katara?! From his favorite cartoon??? Best 10th birthday ever!

Ugh I can't remember if I'm forgetting anything, oh wait right. He can sense when people are trying to trick him. It's like a little itch I the back of his head. His mom can too, so they end up having these conversations where neither one is TECHNICALLY Lying, but like not telling the whole truth and shenanigans. Ei: "your father is lost at sea" does not ping his built in lie detector. So he's really REALLY Good at lying without lying. (Like what fae so in fairytales)

Because of this Percy thinks his dad is a mermaid. Percy is unaware that he is a demigod, he ony thinks his mom is a history-mythos nut. And that his mom is hiding him due to the myth of "if u cut out a mermaids eye and eat it you become immortal"

ugh thats all I can remember rn I'll edit it later.

Oh wait I just remembered since Percy's blood split is 85/15 he kinda can't really be referred to as a Half-blood. That is waaay more than half. Since like Frank blood split is 49/51 he can still be described as half. In other words,

IN THIS AU NICO IS ONE OF THE SEVEN.

and I also ship percico.

All of this is to say it leads to a dramatic scene outside of the doors of death where nico is like nico: "you have to go your one of the seven!"

And Percy is like

Percy: "nope I'm not 50/50 I'm 85/15 that's waaay more than half.....blood"

Nico: "but I can't leave u here"

it's more dramatic in my head and they are not dating by this point, But it's like mutual pining. Percy then kisses him and then pushes him into the elevator in his shock. Tells him to use his wish when he saves the world to use Persephone keyblade to get him and Bob out of Tartarus.

Then since this Percy is op and has seen alta, he blood bends all the rivers in the ground into spikey ice shards cutting the actual Tartarus(not his mortal plain body that Bob and friendly giant guy is fighting while Percy holds the button, but like the actual ground.) into 1000 pieces. And kills him. Like the sky primordial. He also killed poison lady. Btw. I'm so tired ugh what else. They are now stuck in Hell: frozen over.

Percy's logic for cutting up Tartarus with his own insides was as follows:

70% of the mortal human Body is made of Water.

70% of the earth is covered in a Body of Water.

The earth is Gaea, a primordial.

Mortal humans were based on gods.

And gods are descendants of primordials.

It takes a mortal and a god to kill a giant.

it took multiple titans (and a primordial to trick) to kill the sky primordial. His body was cut into 1000 pieces.

Ei: saltwater is Gaea's blood. And so are the rivers. I mean their called Bloodstreams for a reason.

A mortal a titan and a giant kill Tartarus.

Gaea was right about one thing Percy will admit.

If u want to to rid your garden of weeds, you have to rip out the roots.
