Harry's Next Great Adventure in Sunnydale, Chapter 1

-Home Universe-

Harry was sitting in the overstuffed leather chair in his office. He was letting his powerful mind wander the vast amount of different universes to see if any caught his fancy. Should such one capture his interest, he would head to that universe to explore it.

He heard his office door open and close, followed by footsteps approaching him in his comfortable chair.

When Harry opened his eyes, he saw one of his many children walking toward him. Her name was Rose Sarah Potter.

Rose was wearing black leather ankle boots and black low-cut skinny jeans that were so tight they looked painted on her nubile body. She had on a short and tight white halter top that exposed her midriff with the words Daddy's Lil Princess in hot pink lettering written on it. He could easily see Rose wasn't wearing underwear or a bra, as usual. She didn't need to wear a bra, seeing how her breasts were always perky and never sagged.

Rose is 18 years old and 5'5" tall. She had a petite body and weighed 117 pounds. Her measurements were 34-25-34 with C-cup breasts. She had a sandy-beige skin tone with a blemish-free and clear complexion. Her facial features were a perfect mix of the best parts from her mothers and some from his mother, Lily Potter, mixed in. Rose's hair ended about seven inches below the top of her shoulders and was thick and slightly curly. Her hair is glossy scarlet-red and has natural bright gold highlights. Her eyes were expressive and vivid metallic emerald-green. She had a small button nose and naturally pouty heart-shaped rose-pink lips.

In Harry's opinion, which he also keeps to himself. Rose is one of, if not the most beautiful, out of all his daughters. That also doesn't consider how she looks in her other forms, which are even more amazingly beautiful in their own right.

Rose is unique in many ways. She has his sense of adventure and his desire to explore other universes. All of his other children preferred to stay in the universes their mothers originated. Then there is also Rose's conception, which surprised even him with how it happened and how it all began.

As Harry locked his emerald-green eyes with Rose's eyes, he let the memories come forward in his mind of how it all started while sharing them with her as well.

-Flashback-

It was just another friend and family gathering at their primary home out of all the universes they had been to thus far.

In the living room with Harry were his friends and many wives. He met all of them while exploring the various universes out there. They were talking about random things when Harry decided to bring something of interest up.

"I need help with a new project of mine. Would one of my lovely wives like to assist me? You will mostly have free rein to do what you want while helping me out." Harry said in a casual voice while looking around the room.

He loved all his wives equally and thought they were all beautiful in their own ways.

"What kind of project is it?" Samantha Carter asked while looking at her husband.

The beautiful blonde woman was one of his wives from a Stargate universe.

"When I first became an Ascended God, you know that I absorbed the memories of some of my alternates and took over other versions of myself in the Harry Potter Multiverse?" Harry replied with a pleasant smile while admiring his blonde wife's beauty.

A multiverse is a grouping of related universes sharing a common theme or a key person. In this case, Harry referred to the Multiverse with all the universes that involve Harry Potter and the Wizarding World as its primary focus.

There are universes with a Harry Potter who is a wizard and is a member of the Avengers or the Justice League. In that case, it would be a crossover universe of Harry Potter and either Marvel or DC. Crossover universes gathered in clusters just outside of Multiverses.

"Yeah, why do you ask?" Buffy curiously asked while the other people in the room wondered the same thing she was.

"Well, I got to experience my original life as Harry Potter. With different events happening and the background origins changing things up for me. It made me want to experience the same thing again. But with a Buffy The Vampire Slayer universe." Harry replied in a leading tone of voice and a small smile.

"Why would you want to return to Sunnydale and experience it again?" Faith asked in a tone of voice that clearly implied he was crazy.

Several of his other wives wondered why he was even asking for their help when he could easily handle it himself.

'Maybe he wants some company there, or it could be something else. Hmm, if I did it. Then I could use the opportunity to fix a small problem. ' Buffy thought to herself in the private part of her mind while looking at her husband.

Harry and all his wives were mind-linked. It allowed them to mentally communicate and share memories and thoughts if they desired to do so. However, they each had parts of their own minds where they could keep private thoughts and feelings to themselves.

Granted, Harry, being who and what he is, could easily see those areas if he wanted to. But he never looked because he knew doing so would greatly upset his wives.

While he may be an Ascended God of Sex, Harry really hates, figuratively speaking, sleeping on the couch.

"I will help you with the project, Harry. So what exactly do you need help with?" Buffy said while looking at the husband she shares with her sister wives.

"I want to set up a special Seed while also testing something I've recently created." Harry said with a spark of amusement in his emerald-green eyes.

Seeds are what Harry calls the counterparts of himself that he sets up in a universe to see how things go, or he causes the Seed to merge with someone there. But neither of them is connected to him. This way, they aren't all he is, as an Ascended God with all his powers and access to the best technology. They also weren't fully aware of the true nature of all existence, including their own.

Harry sometimes randomly mixes a selection of his powers and abilities from his expanded collection for his Seeds to see what happens. Other times, he custom-builds the Seeds for what he wants to use in a particular universe to see how things go without him going there to actively influence things.

Buffy was about to reply to Harry, but the voice of her sister wife, Cordelia Chase, interrupted their conversation. Just as she usually did when Buffy was having a conversation with their shared husband. It was always annoying when Cordelia did it. Even more so at this particular moment, to the point that Buffy will make a few tweaks to punish her while helping Harry with his project.

"Going to another universe again sounds fun. But I don't want to go back to Sunnydale. How about we go to this other universe instead? I found it from a TV show that I saw a while ago. They have different types of vampires, werewolves, and magic users than Sunnydale. The multiverse is called The Vampire Diaries . You can join with one of your Seeds too." Cordelia spoke up, purposely taking Harry's attention away from Buffy and onto herself.

"Ohh, that sounds great, Cordy. Can I tag along? It's been a while since I got to kick some vampire ass." Dawn eagerly said while looking at Cordelia and also interrupting Buffy's conversation with Harry.

Buffy's left eye twitched in irritation. The blonde girl mentally tweaked her plans to also punish her sister for butting in on her conversation with Harry.

Buffy opened her mouth to get back to the original topic. But again, she was interrupted by her older and, in her opinion, uglier sister wife.

"I was thinking that." Cordelia started saying, which Buffy decided to ignore.

'Yep, I'm definitely getting some revenge on them for this, and it will be fun. Sweet satisfaction shall be mine when I see their faces when they learn what happens.' Buffy thought to herself in that private area of her mind.

Harry felt the familiar slight shiver of fear from being near a vindictive teenage girl who was up to something.

"Let me deal with them quickly, and we can go somewhere quiet to hatch things out. And don't worry, I plan to have some creative fun with both of them in that TVD verse. Also, to make up for them butting in while you were trying to help me, I will link you in so you can watch the results as it happens." Harry told Buffy over their mind-link and got a mental hug and a kiss back in thanks from his eternally hot teenage wife. 'That should smooth things over, I hope. Either way, I'm staying out of it.' He thought to himself as an afterthought.

Harry decided to speak up to get Cordelia's and Dawn's attention. He knew Buffy hated it when people interrupted her or tried to cut in on something she wanted to do alone with him.

"Cordelia, Dawn." Harry said in a calm but commanding tone of voice. "I will get the both of you there. But I get to pick whether you are there as yourself or taking over someone else who is already in that universe. You will only go with a sword that you can hide. But I will ensure you can keep up with the vampires there, strength and speed-wise. Otherwise, you will not get to enjoy it if you just go in and God Mode it. I will even put one of my Seeds there for you both to have fun with if you want to. Also, I get to make a few tweaks if I want to, and you both will get to remember everything you know now, but I get to block certain memories or knowledge if I want to. Lastly, you won't remember any future knowledge you might have of what is to happen in that universe." Harry told his two wives to explain the conditions of his helping them with their little adventure in a different universe.

Like Buffy, he had fun plans of his own. But they didn't need to know that either. Harry was looking forward to getting his memories from the Seed he intends to plant in the TVD universe with Willow and Jenny.

"You've got a deal." Cordelia replied at the same time that Dawn said. "Sounds good to me, Harry."

"Okay, we will hatch things out for that in a bit. But I'm going to get Buffy situated with my special project first. Also, no one can look into my next great adventure in Sunnydale until Buffy returns. I will even block myself from seeing into that universe, too. This way, no one can interfere with it." Harry told Cordelia, Dawn, and the room at large.

He had no idea that blocking the others out, even himself, was something that Buffy intended to ask him to do. But now she doesn't have to. So there is less risk of them, or even Harry, finding out her ultimate goal for Sunnydale and her reason for helping him.

Harry got up and walked to where Buffy was sitting, then pulled her up and into his arms before teleporting them into his private area where no one could see, hear, or get there. The only way to get there is for Harry to take them there himself. He made it specifically for himself if he wanted to get away for a bit or if some of his wives wanted some alone time with him without interruption. Then such a place is available.

"Thanks, Harry, you are the best." Buffy said before pulling him into a passionate and love-filled kiss.

She always loved kissing her husband.

"You're welcome, Buffy. But like with Cordelia and Dawn, I have a few things I want to happen and are non-negotiable." Harry told the sexy girl in front of him with amusement and a prankster's glee shining in his eyes.

"Okay, that should be fine. What is it?" Buffy curiously asked, hoping it wouldn't interfere with her primary goal.

"First is a special Seed of mine, which we can discuss later." Harry replied with a gleam in his eyes while playing with his wife's blonde hair.

"Okay, I also want you to make me a Seed of my own." Buffy said with a sweet smile on her face and saw her husband give her a nod in agreement.

"While exploring the whole of existence, I have seen various other versions of vampires out there. It made me want to create a brand-new vampire breed with a touch of my divine domain just to see how they would work out. That is why I thought Sunnydale would be the perfect place to test it out at. Also, because it was where our adventure had first started. You love, will be that vampire, the Vampire Queen, as some would say." Harry explained with a playful grin while his eyes lit up with delight.

Then he pulled his beautiful wife into a passionate kiss that lasted a few moments.

"Tell me about this new vampire breed of yours, and can I pick the time when I become one?" Buffy asked with a tilt of her head. "Also, I can't wait to see everyone's faces when they find out about a Slayer becoming the Vampire Queen." She amusingly said before giggling.

Buffy planned to spend several years in the universe she was going to so she could achieve her goals. So she had plenty of time to adjust her plans if needed and really drag out Cordelia's and Dawn's punishment if she wanted to.

'Sweet vengeance shall be mine. Oh, yes, it will be glorious, and the two ugly sluts will rue the day they interrupted me when I was talking to my husband.' Buffy thought to herself with the vindictive pettiness most teenage girls have and a giggle in the hidden part of her mind.

Harry suddenly felt a small spike of fear grip his heart and a strong desire for his wife. He was tempted to bend Buffy over and give her a spanking before spending many hours having vigorous sex with her. But he decided against doing so for now.

"Yeah, you can pick when you become one. But I want it to happen at least three years before you leave that universe. This way, you have plenty of time to thoroughly test it." Harry replied before lightly kissing the blue-eyed girl on the lips.

He also looked forward to seeing everyone's reactions to Buffy being a vampire.

Harry then started telling the beautiful blonde girl all the details and the ins and outs of the new vampire breed he planned to make.

While he was talking, the raven-haired god was lovingly caressing Buffy's bare arms and playing with her fingers.

"So, what do you think?" Harry asked once he finished explaining everything.

Buffy was sitting on Harry's lap while listening to his plans and description of the new vampire breed.

The blue-eyed goddess let out a mental whoop of joy. Because of her plans, she could easily accommodate his request without it affecting her goal, given the time frame stipulation that he had added.

After Harry finished describing his new vampire breed and Buffy absorbed the information about them, she thought they sounded really cool. She was looking forward to her role as the queen of this new vampire breed. She also started to mentally tweak her plans because she could use this new type of vampire to her advantage.

"Sounds like it will be fun and interesting. The new vampire breed fits you perfectly as an Ascended God of Sex. They could be your priests who spread your divine gift." Buffy enthusiastically said because she was happy with how this had turned out so far. "Have you named this new breed of vampires yet?" She asked with a curious look on her cute face.

"I didn't mean to make them my priests, as you said. But it's how they turned out when I let my powers guide me into making the new breed." Harry replied with a slight shrug of his shoulders. "As for the name of them, I call them Quasi-Vampires. Also, I won't ask what you will be doing there. You have free rein. Just as long as you don't mess with my Seed too much. But tell me how you want your Seed set up and anything else you might need." He told Buffy before pulling her into a short kiss.

Harry was glad she had accepted it so quickly. Otherwise, he would have to oversee this project himself. That would mess with what he wanted to happen to his special Seed because it would be tempting to interfere in what happens.

"So, here is how I need my Seed set up." Buffy said before she started filling Harry in on how she needed it designed.

She didn't need Harry's help to set up her own Seed because of everything she could do as a goddess and having access to the best technology available. But there are a few things she required that only he could do to make this work how she wanted it. Besides, it was nice when Harry took the time and did things for her.

"Also, I will need a custom Puddle Jumper capable of time and reality travel. So I can get things set up properly." Buffy added at the end.

A Puddle Jumper is a small and highly advanced spaceship made and used by the Alterans. It was designed for carrying things and is a short-range vessel. They didn't come with hyperdrives for faster-than-light travel, but the ones that Harry makes all have hyperdrive engines.

"No problem, Buffy. Let's get this show on the road!" Harry eagerly said with a grin on his face.

He was looking forward to absorbing this Seed's memories when Buffy returned from helping him with his unique project.
