The most powerful (Female Frisk x Male reader)

The Soul of Power

A/N just so you know when it is all lowercase it's Sans and if it's all capitalized it's Papyrus. Oh and I will publish a few more today. Now continue on.

"I need something from you." I said. He looked back at me and asked what I needed. "I need to know magic to better protect everyone." He just looks at me and agrees on one condition, NO KILLING MONSTERS UNLESS ABSOLUTELY NECESSARY, I agree to his condition and he initiates a battle.

Sans' POV

(start the song now) "alright kiddo, in a battle time slows down considerably so it's the best way to train." He nods in understanding, "Alright so what will you teach me first?" he asks. "first up is the most useful and least energy consuming one, teleporting, what you must do first is concentrate on someone, not somewhere like most would think then focus your energy to your soul and....." I teleport behind him, "..... voila." He turned to face me before I even got there "Cool so like this" he warps right on top of my skull while looking down, damn he's fast even faster than me. "exactly. alright next up is floating to do this one must.......uh wow" I say as he begins floating, without instructions. "cool, well next would be a basic attack."

your POV

"Um actually can you teach me your secret attack, the GASTER BLASTER." He stares at me without any pupils "how do you know about that attack, my brother doesn't even know about it." I tell him that I am from a different dimension he looks right through me and sees that I'm telling the truth. "fine but first how to affect gravity around a soul." he goes on for a few minutes until I understand. "now for the blaster you must take in the energy around you and from your own soul then concentrate on the space around you and....." he summons a GB "see..... it..... come..... into..... existence..... however it is the most energy consuming power in my arsenal...... HOW THE F**K DID YOU DO IT SO EASILY YOU'RE JUST A HUMAN!" I look at him and show him why, and just like Toriel he was amazed. "alright lets go" the battle ends and we both warp to Papyrus "heya bro," "OH MY GOD SANS DON'T FRIGHTEN ME LIKE THAT...WAIT IS THAT ANOTHER HUMAN," "yup but he wants to be our friend and protect the other one, and speaking of where is she?" "OH THAT IS SIMPLE SHE CONTINUED INTO WATERFALL."

Waterfall, just by hearing it I could feel my soul cracking. "Guys I need to go" and with that I ran as fast as I could out the door and towards Waterfall, I needed to hurry.

Frisk's POV

I walked up to a passageway, "Hopefully Undine won't be around looking for me." "Ha Ha Ha that's what you should hope for." I look up to see the fish-woman looking down upon me and I become paralyzed with fear. "You are the last one we need so you must DIEEEEE!" she said. "Please please no don't kill me!" I said while crying from the fear. Then Undine summoned many spears and shot them my way, and I just accepted my fate, but nothing hit me, I open my eyes to see a..a human.

Your POV

"I won't let you harm her" I say while I stand over top of Frisk shielding her from the barrage of spears. "F...Frisk run now run to Sans and Papyrus NOW!" She nods and follows my orders, Undine looks at me "very chivalrous aren't we" she asks. I respond "No I just don't want her to be caught in his attack," I look back and Undine looks at where I'm looking and sees a flower with a face. "What the hell is that?" Then It starts laughing and initiates a battle with us (cue his theme) "Howdy I'm Flowey, Flowey the flower, and your souls are mine." Then the battle begins. He summons hundreds of bullets and my souls become visible.

"OH MY GOD! WHAT THE HELL?" Flowey says seeing all of my souls. "I'm from a different dimension and my soul power allows me to absorb souls but it has a risk, if more than ten souls are absorbed then I could blow up or turn into a power source known as a philosopher's stone, I have prevented my unique soul," I hold my soul up to them, "a half human, half monster, golden soul from absorbing these souls, all nine-hundred million of them, because if I absorbed them all then I would surely die." Then all of a sudden Flowey's bulltes shot at my main soul hitting it.

HP 1/99000

I fell to the floor from the pain, then I was surrounded by more but before they hit me Sans pulled me away, but accidentally forced the other souls to fuse with the main one. Him and Undine then proceed to fight Flowey until he ran from them. Sans then realized what he did and took me to his house. He laid me down on the couch and Frisk looked at me seeing the pain I was in, then BOOM I flew out of the house.
