BioTale and UnderShock

by TechnoKino

BioTale: Frisk goes missing and Sans decides to track her down, taking a plane as it crashed into the ocean, Sans decides to explore Rapture and help Atlas out, who knew he would find his baby bones in the same city? Undershock: A Little Sister has fallen down into the Underground, without her 'Daddy' she is defenceless luckily a funny skeleton is a good replacement.

1. Chapter 1

Guys I have a new fanfic idea which could make for an awesome AU and I am slightly surprised of how little there is of this crossover.

I was playing Bioshock Infinite and some times I'll take a break in the game to write or draw, then I was like 'huh...Elizabeth and Sans kinda have the same powers.'

No joke Elizabeth has tears and Sans his shortcuts, but also the whole time thing.

But that's not the idea, I have 2 story sets in mind, I may do both depends on which seems better.

I have 2 name ideas as well BioTale or UnderShock, kinda like the sound of BioTale better.

But Story idea 1:

After Frisk freed the monsters, instead of living with Toriel they set off on their own path.

But Rapture takes kids from the surface, those with no family and Sans losses contact with Frisk.

He catches a plane, sadly it's the same plane Jack also boards.

Luckily for Sans he has his blasters and aborts the plane before it could crash.

Now for this story to work we have to believe either Jack dies in the crash or never makes it to Rapture cause Sans takes the bathesphere to Rapture.

Atlas will try to get Sans on his side (doing the whole wife and son thing).

Sans will then find Frisk with a Big Daddy (pretty early, in the room where Jack would get the Shock plasmid)

He takes out the Big Daddy (guys blaster vs Daddy, yeah Daddy got no chance)

But finds out Frisk has become a Little Sister (I am not making a Frisk female, just what they are called)

That is as far as I have got.

Story idea 2:

A Little Sister fell down (don't need an explanation why or how she fell just roll with it), she only has her syringe with a little bit of ADAM in it.

She leaves the ruins (not gonna spoil how) and of course meets Sans, now Sans is short and fat (no offence Sans).

He'd look like a mini Big Daddy, the Little Sister thinks he is and before Sans can defend himself or stop her, she stabs the needle into his soul injecting the ADAM into him.

At first nothing seems to happen but Sans soon finds out, he can't stop following the child.

Sadness will be a BIG thing here.

What do you guys think?

Would you like a Bioshock/Undertale crossover story?
