Good evening, faithful readers and fearless explorers of the wonders of the ever-expanding Multiverse! This story is one that I've been thinking about for a while, and I think it's gonna turn out great! To prevent any confusion, the story takes place in the universe of Ben 10: Omniverse, during the timeline of Ben 10,000. I will include a few OCs, including my own Biomnitrix alien fusions. Enjoy!
Chapter 1
Far away in a deep region of space, the headquarters of the Plumbers hung suspended far outside the atmosphere of any planet in its vicinity. Within the massive space station's sterile white walls, a strapping brown-haired young man was preparing for a journey. He had lightly tanned skin despite spending the majority of his time without natural sunlight, bright green eyes, and wore a white armored environment suit with black and green accents, a green belt, black gloves, and black boots. This was Ken Maxwell Tennyson, son of the Multiverse's greatest hero Benjamin Tennyson, more commonly referred to as Ben Ten Thousand. Attached to Ken's right shoulder was a standard-issue Plumber's Proto-Tool, a device that had countless applications and was designed for use in just as many situations.
"Still preparing to go to Earth, I see?" Ken turned away from packing his suitcase just long enough to get a good look at the tall figure standing in the doorway of his bedroom. Approximately seven feet in height, with four bulging arms protruding from a black sleeveless T-shirt, a powerfully muscled torso, lobster-red skin, four humanoid stormy gray eyes, and a long mane of black hair, the Tetramand-Osmosian hybrid leaned against the door frame, the top pair of arms crossed over his chest and the bottom pair with their hands in the front pockets of a pair of baggy blue jeans that were ripped at the knees. He wore thick chains for a belt/suspenders combo, and his feet were covered by a pair of boots very similar to Ken's but much larger.
"I know everyone is telling me not to, Gil, but I have to. Uncle Kevin's last known location was a small town in North America," Ken replied to his best friend. Gilgamesh "Gil" Levin was the son of Looma, Warlord of the Tetramands. Looma had wanted Kevin Levin to be her mate and rule by her side, but the Osmosian had ultimately refused and married Ben's cousin, Gwen Tennyson. Rather than choose another mate from among her own race, Looma came to the Plumbers with a request that Kevin's DNA be spliced with her own to allow her to conceive a child, whom she'd chosen a name for after reading a translated version of an ancient Earth legend entitled The Epic of Gilgamesh.
As some couple tend to do, Gwen and Kevin had a fight. Nobody could recall what they had been fighting about, but the argument had gotten so heated that Kevin had left the Plumber base to cool off. He turned off the tracking device in his Plumber badge upon arriving on Earth, and that was the last anyone had seen or heard of him for nearly twelve years. The rest of the Plumbers declared him dead in absentia after a fruitless search, but five-year-old Ken felt in his bones that his not-really-uncle was still alive somewhere.
Gil scoffed and said, "You're an idiot if you think you can leave without me. Not to mention you'd make Blanca upset for leaving her behind, and you know what she's like when she's mad." Rook Blanca was the daughter of Magister Rook Blonko, the leader of the Plumbers and Ben's old partner. She was also Ken's girlfriend. The cat-like Revonnahgander girl was actually quite ferocious when provoked, which thankfully wasn't very often.
"Alright, smarty-pants, if you want to come too, you need to get your stuff packed, too," Ken shot at Gil, who only smirked.
"Way ahead of you, dude. Blanca and I knew you were gonna pull a stunt like this sooner or later, so she and I have been packed for almost a month."
"I was that obvious, huh?"
"Totally. If you're done packing, let's go to the bridge. Magister Rook sent me to find you." The two friends went to the bridge, where Rook, Gwen, and Blanca all stood waiting for them. Blanca, like all Revonnahganders, was covered from head to toe in short, silky blue fur with black markings except for the white fur on her face. Her black jumpsuit with white body armor hugged her feminine curves, and rather than a Proto-Tool like Ken's and her father's, she had a holstered pistol strapped to each thigh and a short knife tucked into each boot. Her face was framed by long, glossy black hair held in place with a white headband, and a small pair of fangs peeked out from her dark blue lips.
Gwen greeted Ken with a brief hug, as he was more like a nephew to her than her second cousin, Rook shook his hand, and Blanca gave him a quick peck on the lips.
"Rook and I were able to pull a few strings," Gwen informed Ken. "We bought a house for you, Gil, and Blanca to live in on Earth, and you'll be given a monthly allowance of American currency to use for groceries, utilities, and personal pleasure. In addition, since you and Blanca are technically minors by American standards, the two of you will be attending a local high school. There are already a small number of aliens living in that town, so you shouldn't have too hard of a time fitting in. So...are you ready?"
"Ready as I'll ever be, Aunt Gwen," Ken replied. The three friends gathered their luggage, boarded a small transport vessel, and began the journey to Earth.

[Royal Woods, Michigan, approximately twelve years prior]
Kevin Levin walked into a bar and ordered the strongest drink that was available. He came to Earth to step away from the problems in his marriage for a while, and would hopefully return to the Plumber base with a cooler head. He tipped the Splixon bartender who poured amber-colored liquid into a shot glass for him and absently scratched the x-shaped scar on his chin. A few years prior, the Plumbers had struck a bargain with the United States Government to allow aliens of all species to be integrated into American society. Scattered communities like Undertown would no longer live in fear of persecution and discrimination by the human race.
"Hey there, handsome. You look lonely." Kevin was brought out of his deep thoughts by a female voice from right next to him. He looked to his left into the face of a human woman with long white hair and eyes that were red and puffy from crying. Despite this, she had a tipsy yet flirtatious smirk on her face. Judging by the ring on her left hand, Kevin wasn't the only one with problems in his marriage. "I'm Rochelle. And you are?" she asked.
"Kevin," he replied gruffly and turned back to his drink and the bowl of stale peanuts in front of him.
"Come on, Rochelle, you've had enough to drink for tonight," said a woman beside Rochelle who had shoulder-length blond hair and a white blouse under a pink sweater.
"Rita, you know you're my best friend, but I'm trying to talk to this stud over here," Rochelle protested, and Rita sighed heavily.
"Okay. I have to get home before Lynn lets the kids burn the house down. Just...don't do something you'll regret. Please?"
"Don't worry, ma'am. She'll be safe with me," said Kevin while trying to ignore Rochelle lightly squeezing his large bicep. Rita looked at Rochelle sympathetically, then patted her shoulder and left. Kevin and Rochelle got to talking, and the conversation eventually turned to the subject of each other's marital problems. Apparently, Rochelle had arrived home from work to find her husband in bed with not one, but three other women, all significantly younger than her. Utterly disgusted by his attempts to persuade her to join his small harem, Rochelle had thrown him out of the house and immediately filed for divorce.
Meanwhile, Kevin kept drinking shot after shot of his drink and got pretty tipsy himself. One thing led to another, and the next thing either of them knew, he and Rochelle were crashing through the motel room he was staying in, sloppily making out while needily tugging at each other's clothes before flopping onto the bed.
When Rochelle woke up the next morning with a head-splitting hangover, Kevin was nowhere to be found and his beloved car sat abandoned in the parking lot. She never saw him again. Nine months after that fateful night, Rochelle died giving birth to Kevin's son, who had her white hair and his gray eyes. The child was adopted by Rochelle's best friend Rita Loud and her husband Lynn, who already had five daughters of their own, and was given the name Lincoln Loud. For the next eleven years, Lincoln was raised none the wiser, and when he began to question his parentage, his adopted parents invented a cover story about him being delivered by the First Lady, strengthening the tale by ordering a blanket with the Presidential Seal on the Internet.
