Ben 10, wielder of the Ultimatrix, has gone on some crazy adventures including traveling to a parallel universe (Generator Rex). But this one has got to be his craziest one yet. Ben Tennyson has landed yet in another universe, the mysterious World of Remnant, a place that is inhabited by Humans, Faunus, and the Creatures of Grimm. Along the way he'll learn to work together with Team RWBY and JNPR, while saving Remnant from falling to darkness by the mysterious Salem with the help of his new team, Team 10 with his friends Rex Salazar from his previous adventure and Zak Saturday the Cryptid Hero. However, he would learn about his special Destiny that would tie his fate to the entire Multiverse while starting his own Family... A Big Family with a lot of girls... Along with their crazy and Wild adventures.
(MAJOR AU where Omniverse didn't happen and Julie Yamamoto is going to be sharing him with Yang and Harem.)

(Please note I will have the Cryptids from Secret Saturdays and Rosario + Vampire Yokais coexist in the SS/B10 world as Cryptids.)

(Reminder: I will NOT tolerate Flame Comments. I am trying real hard to not make this boring. The BlazBlue Cross Tag Battle Chapter with RWBY is Canon. And for Smash Bros. Ultimate, like Kirby, I have very good reasons that this will NOT be complicated. Thank You.)

P.S. The Ben being an Anodite, I've made it so for the Plot he would be involved with Zak's Past Life as Kur.

Jaune Arc Multiverse (Complete) by baaxter588
6 parts Complete Mature
This is an alternate RWBY universe where a counterpart of Jaune was created after the real one fell into the void. He doesn't remember the events of the volumes but now him and the others can be warned. Summer, Glynda, and Cinder are Jaune's aunts in this one, making Jaune the cousin of Ruby Rose (on Summer's side), Oscar Pine (adopted by the Rose/Xiao-Long Family), and Neo (on Cinder's side). Roman and Cinder are married while having Neo as their daughter. Qrow and Summer are married too and Qrow is Ruby's father while they have adopted Oscar. Whitley Schnne is now nicer and is in love with Penny. Oscar, Whitley, Blade, and Bang are the male version of Team RWBY and younger brothers of them but Yin hates Yang, which the feeling is mutual because she sees her brothers as an immature monster, which is hypocritical since she's in it for the thrill of being a huntress. Johann Arc and Sierra Arc are cousins of Jaune but they act more like older siblings. Cardin's family is invited as well but his sister, mother, uncle, aunt, and male cousin don't act like him. There are new students in this universe: Team BLUE and Team PRON from Beacon, Team ARC, Team DETA, and Team BACH from Atlas, Team DOOM and Team HOPE from Haven, and Team DAWN and Team SAND from Shade. Team BLUE's only male member doesn't like his team because of how they treat him and one of them cheated on him for selfish reasons. He is only close to Team DOOM and Team DAWN because they support him but he also is friends with Ruby, Jaune, Velvet, Sun, Penny, and Mercury.
Chaquetrix Ben 10 x Alien harem by Yuutoju22
9 parts Ongoing Mature
The chaquetrix is an alternative version of the omnitrix and unlike the original version it has the power the summon aliens for breeding purposes created by Azmuth as a fail safe in case if the alien species dies out and because he is very interested in how different species procreate in short he is very curious about different species of aliens mainly the woman of those species. In this au Ben finds the chaquetrix the same way every other Ben does a flying meteor in the woods and boom alien appears Ben is 17 years old (age of consent in America versus depending on where you live I read this online let me know if I am correct) he takes an interest in the aliens and grandpa Max is aware of the Chaquetrix but doesn't tell Ben or Gwen about it's purpose Ben kind of gets the impression that hero work is not the real purpose of the watch but wants the help people and genuinely wants to get to know the girls personalities,hobbies,likes and dislikes.Albedo is female as well having an obsession with Ben like a yander stalker type thing hates it when he doesn't notice her flirting/ attempts to hurt him or the aliens in his watch. The au begins as normal as episode one of the classic Ben 10 of 2005 (What a classic show) only he is older and has more aliens like in Ben 10 ultimate aliens but doesn't have the ultimatrix because Albedo made it for the purpose of getting his attention she turns into aliens and their ultimate forms and note: I don't own any art work used nor the chaquetrix this is an au made for fun and all credit goes to the artist of any and all art work used in this and with that out of the way if any one has any ideas or suggestions for the story pls leave a comment I read all of them and like hearing ways to improve stories
Fight Like Hell! (A DOOM x RWBY AU story) by Warlord-Dregon
26 parts Complete Mature
[DISCONTINUED] Attention: This is an AU for both DOOM and RWBY. Some things will be altered or changed involving the protagonist and the lore of DOOM, and it won't follow the story of RWBY. Major changes will be involved for the show. I hope you understand. Rip and tear...rip and tear is all the Doom Slayer knows... After slaying the Spiderdemon, the Doom Slayer, y/n, was sent to Remnant by none other than Dr Samuel Hayden himself. Whether it was an accident or not is a mystery... Upon waking up, the Slayer noticed something was off. He will need to use everything he has to survive the new, harsh world he was sent to. He'll soon learn that the demons from Hell aren't the only demons he will have to rip and tear. His time is not yet over...far from it... Warning, "Fight Like Hell!" will contain the following that may be unpleasant for some people: •Blood, violence, and gore •Strong use of language •Mild/crude/terrible humor •Small amount of sexual themes and references •Use of drugs •imagines showing unpleasant themes I absolutely don't own rwby or DOOM. They belong to their respective owners. I also don't own any pics, gifs, or videos. (Semi-spoil alert) P.s. I know it says harem in the tags, but it'll be small. I'm only planning on having 3 or 4 girls and a VERY slim chance for 5. It won't be all at once either, I'm planning on having development with the love interests. And even though there will be a harem, by the end of this story, the mc will choose only one girl.
Wrought to Calamity - A RWBY and Calamity Mod Crossover - Harem x Male Reader by Argoniangaming
15 parts Ongoing Mature
Remnant, a world which has long known peace. In the shadows, a hidden war wages. Fought between two lovers, who bring their world ever closer to ruin. Yet Remnant is but one of many worlds to exist... In another world, chaos reigns. A Mad Tyrant rules over the land with an iron fist; his will cemented and absolute. The people of this world had long lived in fear until one day... a hero rose. One after another, he slew the Tyrant's servants. There was hope... hope that would soon be squashed. The hero would soon face his hardest challenge yet. The Tyrant's strongest servants, two of whom he thought slain, had returned along with two others. A Goddess of Profaned Flames, an endless Devourer with the strength to kill the very Gods themselves, a Brimstone Witch, and lastly... A Dragon, one with the very blood of a phoenix flowing through its veins, A Dragon of Rebirth. The Hero would fight but would ultimately fail, but not before taking the mighty dragon with him. All seemed lost for that world, but fate intervened. For in the world of Remnant, a faunus would be born. He wouldn't know it yet, but the very soul of the dragon slain in the other world resided within him, and that dragon's name........... was Yharon. #5 #Cinder 2/26/2024-2/27/2024 #4 #Cinder 4/5/2025 #3 #Cinder 4/8/2025-4/9/2025 #4 #Pyrrha 8/6/2024 #4 #Ozpin 4/9/2025 #3 #Ozpin 4/5/2025-4/8/2025 (I do not claim ownership of RWBY, Terraira, or Terraira's Calamity Mod.

I do not own WH40k, Arknights, Azur lane, or references to other franchises, or Halo for that matter.

No, this is not an official work, like my last story, simply a fanfic, with added elements. Trails of darkness, Is no longer canon in my fanfic's lore. I do not own any of the videos or pictures used in the making of this Fanfic series, and all content goes to original creators. This is the real first book of the series, the prequel will be modified to fit the lore established in THIS book. Also, some of the grammar in the first few chapters is . . . Questionable, to say the least, but please ignore my rushing to get chapters out at first, because it gets better later on.
