So how this all started was when one of the darkness's greatest enemies. Samatha spinel. Yes, it is the same daughter of spinel you saw in my Zamasu book. Although this is one from an alternate timeline. Anyways they were in a fight. Here's the fight.

Sam and The Darkness were in a fist clash. They kept blocking each other's attacks. They were currently in a stalemate of punching and blocking each other. They were complete equals. However, while they had the same strength Darkness had more experience being an over a thousand years old man. Sam was still a bit of a rookie when it came to fighting. IT eventually found an opening and punched sam square across the face and kicked away. It looked at the gem hybrid in front of it and says.

Darkness: I'm so tired of you interfering with me destroying universes. It used to be quite fun but now it's gotten stale. I invade a universe and you keep reincarnating to stop me in that universe. I'm bored of you keeping on doing this. You should just let me do what I've been doing. Destroying universes. I'm called the destroyer of worlds for a reason.

Sam: *coughs blood* Now I wouldn't be much of a hero if I did that. I won't just let you kill all those lives.

Darkness: hehe. You're the same no matter what version of yourself or reincarnation. Welp. It's time for me to end this cycle by getting your soul!

The dark being goes to try and attack her but right before it hits she dodges it and fires a beam of light magic directly at its chest. It screamed in agony as light-based attacks hurt it greatly. It fell to its knees and look up as it see Sam's hand in front of his face, a light magic attack prepared to fire. It then said to her as she was charging it.

Darkness: You gonna kill me, your best friend? We may hate each other but I'm all you've got left, Sam. No one else knows you like me. I'm one of the closest things you have to family. Are you gonna kill me?

Sam looked at the darkness that used to be her friend with eyes filled with nothing but pure hatred. How dare he- no It say those things!! How could it say that when it was the one who had her kidnaped and adopted by an adoptive abusive family?! How could it say that when it was the one who make her forget her own family?! How could it say that when it killed her mother, spinel in front of her to make her unlock her powers?! How could it say that when it was the one who made her life a living hell?! She wanted nothing more than to kill this being who used to be her friend but then remembered some of the good memories that she had with it when it used to be human. Back when he went by a different name. Dolion adofa, Her best friend. She remembers how he always cheered her up when she was sad and how used to go get ice cream together. She dissipated the magic blast and creates a portal to the left of both of them. She then says as cold as possible.

Sam: as a memorial of our past friendship I am letting you live. Now you get to go through this portal and you get to live out your days in whatever universe or void you chose.

Darkness: *tries to get up but is doing so slowly* You wanna give me a lift?

Sam(coldly and monotone): No.

Darkness: Suit yourself.

It gets up and limps to the portal however just before it can go through the portal Sam grabs it's arm tightly, looks into it's dark grey eyes, and say to it.

Sam: Oh and If you commit a felony I will come over there and end you. Slowly and painfully, just like how you killed my mother! Do you even remember her?

Darkness: ...Of course I do. I remember how fun it was to slowly take apart her gem piece by piece. *Sam growled at this, as her eyes glowed a fiery purple* I'll see you soon, sam. My dearest friend.

It says as it goes the portal. Sam sighs of relief, teleports to her universe, goes to her house, and lays down on her bed. As she slowly falls asleep she wonders if she made the right decision on sparing Darkness. However, she remembered what uncle steven taught her, "Everybody deserves a second chance". She also remembers what her mother taught her, "give someone enough rope and they'll either save themselves or hang themselves." She decides to sleep on it. However, while sam was catching some zs, Darkness was in a dimensional gateway and deciding which universe it should go to. It then decides on a rather interesting one, Deltarune. It should be able to make the determination user there his puppet before the player does! He then speeds off towards that universe to a time where the player doesn't have influence over Kris's life, Kris's past!

Meanwhile in the Deltarune universe

6-year-old Kris was playing catch with Asriel, Their parents talking to each other when suddenly Asriel throws the ball too hard and makes it roll into an alleyway. Worried how their parents would react Asriel says

Asriel: sorry man, I'll get that.

kris: no, it's fine. I'll get it, bro.

Asriel: are you sure?

Kris: Positive.

To be honest he didn't feel up to it. He was always quite scared of alleys, that some monster would attack him and despise him for being human. He had a few bullies like that. Asriel stopped them but their words stuck with him. "Your choices don't matter." Anyways, he walked into the alleyway, terrified, and eventually found the ball. He rushes over to grab it when suddenly a black substance goes on his hand. It then bites his hand. Kris, in pain, tosses the thing off of him. It then grew bigger and bigger. It eventually began an abomination that vaguely resembled a human shape. It then open its grey eyes and looked at Kris. The human stared back with fear. Right then and there it reached down and scratched kris across the chest.

(The first image of the black entity is what the darkness looks like. Pretend chara is kris. The upper image of black eyes is what Kris'll look like after possession.)

Making it gush out blood. Kris screamed in pain which caught the attention of Asriel, Toriel, and Asgore.

Toriel(distant): KRIS!? ARE YOU ALRIGHT? WE'RE COMING!

Black Demon: Don't let that yell fool you. No one will be able to save you. *laughs like the video below*

It then turns back into a blob and goes inside of the wound. It uses the wound to go although his body, taking all of it over and being in full control of it all. Over the past few weeks, it learned how its new human body worked, what went where, and how it ticked. After he was done toying with his new body, the being woke up on a hospital bed and looks at his hands. Huh. It never considered himself to be him. wow. He did it again! It must be the human side he now has acquired. He then hears a feminine voice speak to him, mostly his doctor.

Doctor: It's a miracle that you're alive!

"Kris"(Darkness possession): Really? Well, what do you mean miss?

Doctor: W-w-well it would seem while you were in your coma y-your heart stopped. But you just seem to come back to life. *whispers* just now.

The darkness smiled sadistically behind his human flesh and inside his human nervous systems. You could say that he became the inside of the body and that the human flesh is like a costume. A flesh suit if you will. Anyways he was happy that he was able to cause his human flesh suit some suffering without completely making it non-functional. Hehe. He was now treating the vessel he was inhabiting as an object instead of a real person with feelings and emotions. Hehe. Good! He wants to be cruel. He's glad personality trait carried over to this vessel.

Doctor: Hey you okay? You look like you went dormant for a sec.

"Kris": Yeah. I'm fine. I just was thinking about it. Anyways. welp, I'm up now I'm gonna go now.

Doctor: now wait a minute. You should rest here.

"Kris" growled a bit as the darkness wanted nothing more than to kill this woman and gain some exp but this body is too weak right now and it would draw way too many eyes. As much as he would love to end this woman, to see the life fade from her eyes, and then feel the exp course through his veins he lays down on the bed begrudgingly and goes to sleep. He wakes up in Kris's mind and the kid has chains around his wrist, ankles, waist, and neck. He was crying and looked up at the dark humanoid figure that was in front of him and said

Kris: Why? What did I do to deserve this fate? I've done nothing wrong? I'm just a kid living my life? *sobs a bit* Tell me. Who are you? I want to know who it is who finds it fun to take over a kid's body!

At first, he didn't know how to answer this question. For as long as he could remember he went by, "the darkness," but never actually bother trying to remember his true name. He looked deep inside himself, trying to get just a fraction of his past self when he remembered something. He believes it's his name. Dolion Adofa. He remembers some of his other past stuff to but seeing as how his origin story isn't out yet I can't tell you what right now. However, when it is out I will edit this. Anyways Dolion, with his newly acquired knowledge, then responds to his new puppet.

Dolion: Well, fleshling I was greatly damaged in battle and I needed something or really someone to possess. You were about the closest thing I've got. Hehe. Now as for my name it's Darkness but you can call me by human name, Dolion adofa.

Kris: Hehe. I'll call you by your actual name, Demon!

Dolion: hehe. You're gonna be a fun puppet.

For the next 2 years, Dolion had mentally and physically tortured Kris as he used his powers in the mindscape to attack his mind and out his body through hell. Training it and making it get into loads of fights So he can get his versions of zenkai boosts. However, he noticed that kris's family was starting to get suspicious of him so he gave kris back control but he would make sure that Kris was still getting bullied so that they could get zenkais. We're now 3 years later and Dolion decided to relax and as kris went to sleep so did he. For he has still has 5 more years before the player arrives and tries to take his puppet. There's only room for one puppet master and that's him. Hehe. He'll show them the power of darkness.

And that's it for chapter and story 1! Now, this was me doing some experimentation because I was thinking of doing my own Ut Au and having my character take control of just a normal civilian and doing all sorts of chaos. Anyways here are some memes for your time. Thank you for reading my book and I'll you guys in another one. I'm gonna update the descendant of x, Sonic oc x dbz, demonic speedster meets alien gems, and Divine wrath stories tomorrow or the next day. See you then! Bye!
