Hello~ I've had this idea for a while and decided to write something for it. This takes place after the Deathly Hallows… for a bit (You'll see what I mean later on) and Harry being the MOD I decided to have a little Undertale AU twist, that is, Harry being Death also known as ReaperSans.

Please note I Do NOT own Harry Potter, Undertale, Or most of the AU's in this. I also probably don't own any fan work you may recognize, such as that one AU Christmas comic. I don't own that, how about I say: If you recognize it then I probably don't own it.

Thank you and Enjoy~

Harry stared at the wall in his bedroom, bored out of his mind. Being the Master of Death lead to a few changes. First, any one or anything he touched died. He learned this during gardening when all the plants and bugs died when he touched them. He did find a solution, though. All he had to do was wear gloves all the time. He really wanted to try punching Malfoy with his gloves off though, just to see if it was the same for humans. Change two, was he now was a skeleton. Literally. He could make himself look like a human but it took a lot of effort. And change three, he had access to the Void and Anti-void now, though he really didn't see a difference. One was pitch black and the other a bluish white colour. And with access to that, came the other AU's.

Apparently he decided to be Human and take a break from his job for a while, as says Geno, one of his… friends so to speak. And many of the AU's were surprised to see him back so soon. Memories had slowly been coming back to him as well, like that time in the anti-void he deliberately… He should probably just apologize to classic sans and not dwell on the fact that he could have killed him. Harry- excuse me, Death frowned, thinking of when he could do just that, unknowingly making his way to the anti-void. Blinking, he looked up and groaned. He really needed to stop doing that when he spaces out.

He decided to walk around while he was here. The anti-void was a bit 'homier' than the Void, there was a few buildings that the AU's shared, much like apartment buildings, that they could stay in and come and go. Each also had a large kitchen, living room, and a few extra rooms to be used for clubs, like Friend Cub or Science Club. Making his way to building two, he was a bit surprised to see SwapSans, better known as Blueberry or just Blue.

Blue didn't seem to notice him, so he continued walking to his room.

Death sighed, flopping onto the bed. Maybe if Geno came around he could go and torment him. It wasn't very likely though. AUs tended to stay in their AUs. They would come around here every now and then, sure, but most of the time they stayed in their own timelines. It could get quite lonely sometimes, here. Then, then Death had an idea. The best Idea he has had in a long time.

Running down to the living room, he caught Blueberry just before he left. "Hey Blue! Hold on, I need to ask a favor from you if ya don't mind." He said walking towards the excitable AU. Blueberry turned to him. "Oh! Hi-a Death. I didn't notice you were here! Heh, sorry about that." He apologized. Death waved him off. "Nah, its no problem, but can you send these to Geno, Classic, Science, and have one yourself, as well as choosing a Sans to give one to?" Death asked. Blue nodded. "No Problem! I have to get going now, so see Ya!" Blueberry hopped through the gateway portal-y thing.

Now all Death had to do was wait.

Sifting through his mailbox, Classic found a black envelope with white ink written who it was from and who it was for. Ignoring the rest of the mail, Classic went inside and read the letter.

Death Here,

I was getting bored -again- and had an idea.

I'm seeing if a few different AUs, including yourself,

wanted to be a part of a little outing, so to speak.

Remember when I went as a Human a while back?

Well it's a pretty odd world. So I wanted to try

again- maybe save a few people. But with a few

other AUs to help me out, and having us retain our

memories. As for the whole 'being human' part, you

will go to whichever human would fit you most. If

you agree, please reply and come by to the Anti-Void in an hour. Thanks

-Death

Classic went and got a sheet of paper, scrawling 'yes' and throwing it into a rift leading to the anti-void. "Hey bro, I'm gonna be out for a bit." He said to his brother and left, taking a walk.

Geno was sitting in the void quietly when a letter hit him in the face out of nowhere. Grumbling, he read the letter, and glanced around. Truth be told he was getting a bit bored. He hastily scribbled "yes" and sent it through to the anti-void. If it would get him out of here for a bit, he was in hands down.

Science was sipping on a mug of hot tea, leisurely working on some blueprints for something or other when a black envelope appeared out of nowhere, sitting on his desk quietly. Shrugging, he opened it and read it, smirking. He sighed. Might as well tag along, just to make sure things didn't get too out of hand. You never knew with Death and Geno. He scrawled 'Yes' Neatly on a spare sheet of paper and sent it to the anti-void.

Blue was thinking about who to give the extra as he read his note. Humming, he smiled, thinking of just the Sans. Absentmindedly he wrote a quick "Yes" and sent both notes off.

A figure sat alone in his room, a letter appeared above him and promptly fell on his chest. Blinking, he read the letter, and scrawled a "yes" and sent it off thinking. This could be fun…

Death sat on the couch, waiting for the replies when all the letters simultaneously flew straight into his face. He felt like this was Karma, though he didn't know what for. Reading the replies, he smiled. This was going to be fun. Or, at least it wont be boring. He did have to wonder who Blue chose though. He supposed he will find out in an hours time, when they all come to plan it out and leave.

There was a knock on the door, and an excited Blue came in. "Hey Blue" Death greeted. "Hello~" "So, who did you invite?" He inquired. Blueberry grinned. "Now that would be telling. You'll see, though he's probably going to be the last to arrive." Blue said happily. "Whatever you say." Death said quietly. At that time the other three arrived. "Yo" Classic greeted. "What he said." Science said. Geno just nodded and went to the kitchen to get a glass of water, and came back as quickly as he left. Another sans came in, one Edge, from Underfell.

"Now that were all here" Death started, "I might as well explain this world to you. First off, its on the surface. Second there is magic, and we will be attending a school for magic in Scotland, a place with funny accents. Third, there's a mass murderer on the rise wreaking havoc and id like to stop him with the least amount of lives possible this time." He explained. "Alright then, so when do we leave?" Science asked. "Now, actually." Death replied and snapped his fingers, and then, they were gone.

Back in the Harry Potter Universe, six toddlers woke up as new people. Two as brothers, one as a lonely heir, one a quiet studier, one a rich kid with a really weird last name, and one, the boy who lived.

Hello again, any guesses as to who is who? I'll leave you to ponder, thanks for reading!
