Omarnosian10: Hello, readers. This is the 7th crossover I made.
Ben: And the first sequel you ever made.
Rouge: Yeah, you told the readers that it'll take a few weeks, but it was actually a couple of months!
Omarnosian10: Because I had a lot of ideas on my mind, and I'm keeping my New Year's Resolution to make a new crossover once a month.
Shadow: You could've done the sequel in February, but no, you had to make a Ben 10/Rosario + Vampire crossover.
Rouge: And you gave Ben a harem! If I ever break the fourth wall, I'm so going to teach that monster harem that no one takes Ben from me!
Ben: Rouge, calm down.
Omarnosian10: That was a different version of Ben.
Ben: Yeah, I like soccer, and he likes football.
Shadow: And he has more forms then you, and has the ability to change his limbs at will, and he's more muscular, and you're scrawny.
Ben: HEY! I'm not scrawny!
Shadow: Compared to him, you are!
Omarnosian10: That's enough! Now that you three have given your opinions, ON WITH THE SHOW!
Chapter 1: Meet the Parents
(Tennyson House)
Sandra Tennyson sighed as she washed the dishes after a delayed, but quiet (If you read Hedgehog 10, you know why) dinner with Carl. As always, she was just going through the motions. A month ago, their son Ben had sacrificed himself to prevent the world from looking like Ben. When Gwen told them the news, they were sad, but proud that Ben sacrificed himself for the greater good. Carl was also worried about their son. A week after his 'sacrifice', Gwen came back with news that Ben may be alive, because she can still sense his mana. Grandpa Max told her, Kevin, Manny, Alan, Pierce and Helen to meet him at Plumber HQ to locate him. Ever since, Sandra has been preparing an extra plate of each meal in case Ben returns. When each day passed, their hope has died down little by little, but they still kept hoping. Neighbors and friends offered condolences over Ben's disappearance. They never believed Will Harangue on the news, since they watched Ben grow up and knew that he has a good heart. They appreciated it, but it was still not enough to bring Ben back. Suddenly, the door bell rang. Sandra put down the dish she was cleaning and went to see who it was. It was probably another sympathetic fan of Ben's who wants to offer some emotional support. She opened the door and stared shocked at who is standing in front of her.
"Honey, who is it?" asked Carl as he came downstairs before he stopped and stared at the person in the door. Standing in front of the doorway, with a smile on his face, is none other then Ben Tennyson.
"Hi Mom, Dad, I'm back." said Ben nervously.
"BEN!" cried Sandra and Carl as they hugged Ben. Sandra was crying tears of joy. Watching from a safe distance, upside down a tree branch is Rouge. She knows that she doesn't have to hang upside down like a bat since she became human, but old habits die hard. Rouge couldn't help but shed a few tears at the heartwarming moment.
"Ben! You're back! I thought I would never see you again!" admitted Sandra.
"Are you hurt? What happened? Did the explosion have any side effects?" asked Carl as he pull back from the hug, along with Sandra and looked Ben over.
"And where did you get those black finger-less gloves and black-and-green sneakers?" added Sandra as she noticed the minor change in clothing. Ben chuckled before he looked down.
"Mobius." answered Ben.
"What?" asked both parents confused before they noticed Rouge hanging from the tree branch. When Rouge noticed the parents looking at her, she waved nervously before leaping off the tree branch and landing gracefully. Rouge then walked toward the Tennyson family.
"Ben? Who is she?" asked Sandra. Ben sighed.
"Mom, Dad, you might want to sit down for this." suggested Ben as everyone enters the house and the parents sit while Ben and Rouge stand in front of them. Sandra and Carl are currently looking at Rouge suspiciously, making the girl in question sweat nervously, which was something she never did before.
"Mom, Dad, I'd like you to meet Rouge." introduced Ben as he looks at Rouge.
"Rouge, I'd like you to meet Sandra and Carl Tennyson, my parents." introduced Ben as Rouge waved nervously. Noticing Rouge's nervousness, the parents stopped looking at her suspiciously.
"Now that the introductions are out of the way, care to explain?" asked Carl. Ben scratched his head as he sat down on a nearby chair.
"You see, the bomb that was supposed to make people look like me was actually a DNA Re-writer designed to get my evil twin back to his Galvan form. The Ultimatrix has somehow messed it up and teleported me and Albedo to a place called Mobius. It's a planet inhabited by anthropomorphic animal-like aliens called Mobians. As a side effect of the teleportation, Albedo and I turned into Mobian Hedgehogs. I met this group called the Sonic Heroes, technically Mobius' version of the Plumbers. Rouge is one of them." explained Ben.
"Hold on. Not to sound rude, but if this girl here is part of a group of heroes, then why is she here?" asked Carl, making the young couple blush before Rouge turned toward Ben.
"Ben, do you mind calling your other friends to tell them that you're okay? I want to talk to them alone." asked Rouge. Ben nodded as he went to go upstairs.
"Not so fast, Benjamin Kirby Tennyson. You are sitting your butt right down in the chair. I have a feeling you have something you want to tell us." said Sandra as Ben stopped in his tracks with a groan while Rouge raised an eyebrow.
"Kirby?! Your middle name's Kirby?!" asked Rouge with puffed cheeks, trying to hold her laughter. Dropping his head in defeat, Ben plopped himself onto the nearest chair. Calming down, Rouge gave Ben a sympathetic look because she knows what the real answer is.
"Mom, Dad, the thing is... " paused Ben nervously, making Rouge stare at the parents determined.
"Ben and I are boyfriend and girlfriend." admitted Rouge, making the parents stare at her wide-eyed, along with Ben. Rouge knew that they had to get this over with and that there was no point in delaying the inevitable. She understood that Ben would be under a lot of pressure now but she was going to stand by his side. Closing his eyes and covering his ears, Ben prepared for the worst. But what he didn't prepare for is to hear sobbing. Ben opened his eyes to see Sandra crying tears of joy on Carl's shoulder.
"When did that happen?" asked Carl as he pats Sandra on the back.
"A week after I met him." answered Rouge as both parents pull back from each other and stared at her wide-eyed. Ben gulped again as he slowly turned his head to face his parents.
"How did you meet exactly?" asked Sandra.
"When he came to Mobius, he found me and my friends trapped in a force field created by one of our enemies, Dr. Eggman. Ben's Ultimatrix also had a side effect, which allowed him to merge the selected DNA with his Mobian DNA. He saved us, and shortly after, he fell unconscious, we took him to our base. I was the first thing he saw when he woke up. It was like love in first sight when we saw each other. He saved my friends again when they were attacked by Dr. Eggman's firefly robots. I didn't know he left when Sonic called me. I was worried about Ben. I was relieved when they came back, and Ben told us about the Ultimatrix, except for the fact that he was human. It was getting late so... " paused Rouge with a blush. The parents look at her suspiciously until Ben stood up and put his arm around Rouge's head.
"Rouge offered me to sleep in her room after I told her that I was going to sleep on the couch because I didn't want to be a burden to her team. I accepted her offer because she can be very persuasive. She asked me if I had a girlfriend, and that brought back some painful memories of Julie. I told her I didn't anymore and she asked if I want to talk about it. I didn't want to, but the next night, I told her about Julie and asked her out on a date set on the week after. After we had a good time on it, I (blush) kissed her and asked her to be my girlfriend. She said yes with another kiss, but the moment was ruined when we got inside the base and found out that her friends were betting on her relationship. Vector begged to not do anything to him because he was one of those who supported us. The others got a taste of Rath." explained Ben. Carl and Sandra slightly paled, remembering what Rath is like. The parents stood up and went to the door and opened it to look outside. They came back in and closed it in a few seconds.
"What were you two doing?" asked Ben curiously.
"Sorry, Ben. We were just checking if Kevin is outside. You know how he likes to tease you about this stuff." answered Carl, making the couple smirk.
"Don't worry, Dad. Rouge took care of that. She's a mean kicker." chuckled Ben, remembering when Kevin volunteered to come with Ben to tease him and Rouge kicked him between the legs like the first time they met. The parents nodded before Carl thought of something.
"So where is she going to live?" asked Carl.
"With us. There's a guest room beside mine, remember?" answered Ben. Carl nodded.
"But where are the rest of her clothes?" asked Sandra before Ben face palmed, completely forgetting about that and realizing that the only clothes Rouge has are the ones she is wearing and the Omniverse Omnitrix. Suddenly, a yellow flash occurred between the two couples before boxes appeared with Rouge's name on them. Everyone stared at them wide-eyed.
'Did Paradox do this? Nah, when he does this, the light is blue, not yellow.' thought Ben before Rouge took out a note taped on the box.
"What's it say?" asked Sandra.
"Dear Rouge, when we got back home, I realized that you forgot to pack since the decision was so sudden, so the girls packed for you and I used my Chaos Control to move them to your current location. I know you can't write me back, but I'm sure we'll meet again someday, sis. From Shadow the Hedgehog." read Rouge as Ben looked over her shoulder.
"P.S: Ben, if you even think about looking at her undergarments, you'll find out why my name's Shadow." added Ben as he slightly paled.
"Shadow's your brother?" asked Carl. Rouge shook her head before she put the note in her pocket.
"We practically grew up together, so we treat each other like siblings." answered Rouge before Ben yawned.
"After everything that happened today, I'm going to get some sleep." said Ben as he walked upstairs to his bedroom.
Omarnosian10: Done.
Shadow: Really?
Omarnosian10: Sorry, this is sort of a prologue before the next chapter, which is the first 2 episodes of Ben 10: Omniverse.
Rouge: Will I transform for the first time next chapter?
Ben: Yeah, I'm pretty sure.
Omarnosian10: And one more thing. Rouge is going to name her aliens differently, so PM or tell me in the reviews what names you want me to give her aliens, but nothing like Speedy for XLR8, Hot Lady for Heatblast, or She-Beast for Wildmutt, please. And tell me the designs as well.
