"Look up in the sky," said a female stranger, capturing the attention of everyone around.
"What's that?" asked a male stranger.
"Is it a bird? Is it a plane?" a random stranger blurted out.
"It's a bird, it's a plane," exclaimed another random stranger at the top of their voice.
"It's Tetra!!!" shouted a random female stranger, pointing in the direction of the flying figure in the sky. They all felt relieved, hoping to be saved.
Tetra soared upward in the sky, almost reaching the sun, and displayed her superhero pose as a huge display name of her appeared on the screen. It was an advertisement showcasing Tetra's heroic deeds to the people of the United States of America.
Welcome to Maniverse 88 - Earth D73 - Multiverse - Universe 69735, where the Americans are protected by their one and only true hero called Tetra. Tetra is the defender of this universe, but before we delve further, let's explore Tetra's past.
Long ago, there was a female Tetronian known as Tetrix who fled her savage home world, known as planet Tetron, and arrived on Earth. While on Earth, Tetrix kept a low profile, blending in with humans, even though her original world was more violent. She found herself in the USA and got a job as a reporter, secretly saving lives with her powers. Over the years on Earth, Tetrix began to understand that there was more to life than meets the eye.
She eventually fell in love with her coworker Damian, who wasn't bothered by Tetrix being from another world. They both lived happily and decided to start a family. Tetrix and Damian were aware of the price, as Damian tried to convince Tetrix that the world needed her. Giving up her powers to start a family would put the world at stake.
Tetrix joined the secret USA hero association known as "The Mystical Order of Supremacy" and protected the universe from planetary and universal threats. The Mystical Order of Supremacy consists of heroes from different races and planets, some with genetically acquired powers from Earth, experiments, other maniverses, different multiverses, and beyond.
The Mystical Order of Supremacy, aided by Tetrix, has defeated numerous evil extraterrestrial beings seeking to conquer their planet. After retiring from superhero work, Tetrix and Damian moved to New York and had a child named Tetra, a half-tetronian, half-human hybrid. During the birth, Tetrix sacrificed her abilities to give Tetra life. Tetra possessed limited superhuman abilities and had a maroon blood, not lethal when diluted with advanced technology. Growing up, she learned to balance her alien and human sides and was encouraged by her parents to use her powers for good.
Tetra excelled as a student at NYU and got a job at Gothamist and The Daily Beast with her best friend Thelma. They had a close bond, akin to sisters or lovers. Tetra faced and defeated formidable foes, sometimes with the help of the Mystical Order of Supremacy. Most of the races from the Order recognized her as Tetrix's daughter. Despite knowing about her origin and her mother's adventures, Tetra was unaware of her secret brother, a full-blooded tetronian named Tetron.
After years of secrecy, Tetra finally learned the truth through her mother's dying words following an alien invasion by rebellious conquering invaders known as the Tetronians. Not only were these Tetronians allied with corrupt Xentronians who sought to conquer their universe, but they were also able to locate their former comrade Tetronian, Tetrix, who happened to be an Earthling. Despite her advanced age, the Tetronians and Xentronians recognized Tetrix and were disgusted by her appearance, seeing the effects of aging and wrinkles.
"You've fallen from your mighty position," a female Tetronian sneered at Tetrix. "Once a conqueror of worlds and dominator of universes, now reduced to this pitiful state, willing to die for the sake of love with a human."
Tetrix pleaded with them, saying, "You don't have to do this. This world hasn't done anything to you."
"We are conquerors of worlds. This is not new to you," replied another Tetronian with a sinister look.
"Where is it?" demanded a male Tetronian. "That abominable creature you created."
"Don't you dare call my daughter that!" Damian yelled as he emerged with his shotgun, cocking it against the aliens who looked at him with surprise. Disgusted by Damian's defiance, a female Tetronian used her tetra beam to brutally split him in half after he shot one of them. However, this display did not faze the aliens, who proceeded to approach Damian's wife, prepared to molest her.
Meanwhile, Tetra was engaged in battle against the invading aliens, though she was unable to defeat them. Despite this, she managed to protect innocent victims from harm. However, something felt awfully wrong at home. Using her tetra vision, she spotted her family in danger and rushed to their aid. Upon arriving, Tetra witnessed her mother being sexually abused before her eyes. Determined to save her mother from the savage Tetronians and Xentronians, Tetra fought back, only to be caught by the neck by another female Tetronian who effortlessly unleashed a brutal beating on Tetra, despite her valiant efforts to fight back.
Tetra was defeated and forced to her knees, stripped naked by the Tetronians. Her mother, Tetrix, pleaded for her daughter's life. Before dying, Tetrix revealed the existence of Tetra's brother, Tetron, which she had kept secret. A male Tetronian, unimpressed by the emotional scene, killed Tetrix by ripping off her head with his bare hand.
Tetra's anguish caused a powerful reaction, and her thoughts were read by a male Xentronian. They discovered her friendship with Thelma and teleported Thelma to their location. Thelma witnessed the gruesome scene of Tetra's parents' deaths and saw the fearsome alien races.
The male Tetronian taunted Thelma, calling her and Tetra weak. He demanded Tetra to call her brother Tetron. Despite Tetra's pleas and confusion, she claimed not to know who Tetron was, having never met him before.
Amid the chaos, a massive spaceship crash-landed nearby, with an advanced being emerging from it. The being used advanced technology to kill most of the Tetronians and Xentronians.
They fought intensely and vigorously, but the strange being proved to be immensely smart, strategic, and powerful, maneuvering their tactics skillfully. The evil tetronians and xentronians put up a good fight against this being, so much so that they took it to the next level of shaping realities and altering the fabric of existence. However, this strange being alone was able to overcome the evil races of invaders and saved the planet. With its cosmic tech and abilities, the strange being restored their planet and saved the United States of America as well. Most of the evil races retreated to where they came from. After the aftermath, this strange being revealed itself by unmasking its appearance and introduced himself as Ra'bby, the only third surviving race of the xentorian.
As the years passed, the identity of the xentorian named Ra'bby was kept a secret by Tetra from the rest of the world, including the USA government and the mystical order of supremacy. Tetra and the xentorian lived in New York and had a female child named Xentra, who is a tribrid xentronian (half tetronian and half xentorian).
Xentra, being a tribrid Xentronian, possesses immense abilities with absolute control over her powers due to the fact that her parents are aliens - her mom being a half tetronian and her dad being a full xentorian. She receives proper training on how to use her abilities for good.
Ra'bby explained his arrival on their world, being saved by Pi-minus and Pius to watch over their heirs. He was cut off from his mission due to a tremendous explosive shockwave from Xenda, which sent him off course into the nulliverse. He escaped with the aid of the xentorium core infused into his ship and ended up in Maniverse 88 - Earth D73 - Multiverse - Universe 69735. His mission to watch over Pi-minus and Pius heirs was unaccomplished, but he was able to monitor their trajectory course, believing that one day they would meet again.

Xentra is a smart, dedicated teenage girl who excels in her studies and has been offered a place in the mystical order of supremacy hero association, where she fights side by side to defeat evil and save the universe. She was told many stories by her parents about her grandmother's (Tetrix) achievements and was taught how to speak the xentronian language and about her place of origin.
One day, there was a crisis on Earth caused by one of Xentra's mother's nemesis who wanted to take over the city. The villain confused Xentra for Tetra after spotting the symbols on Xentra's costume. After an intense battle, Xentra defeated the villain's armies of robots, but the villain decided to use her last trump card against Xentra.
"Stop right there!" Xentra said with an authoritative voice. "Your reign of terror ends here."
"How long have I waited for this moment, Tetra," replied the villain. "Are you back from retirement? I was beginning to wonder if you had ditched out on me after fifty years of what we've shared together."
"Well then, shall we begin?" the villain added while exposing her to tetrenite. Unknowingly to her, the tetrenite wasn't effective against Xentra.
"What is this trickery? You should be susceptible to tetrenite, Tetra," said the villain in confusion. "This has always been my trump card, my last resort in defeating you and getting away. How is tetrenite ineffective against you?"
"That's because I am different. The name's Xentra," replied Xentra. "My mother has told me a lot about you, Lady Gag. It's time I take you in."
"I see that now, the uncanny resemblance," replied Lady Gag. "You're truly your mother's daughter, but I'm not going down easily," she added with a maniacal laugh.
Lady Gag unleashed her full potential to battle against Xentra, who successfully overpowered her opponent and saved the day after their intense fight. Lady Gag was defeated and taken into custody by the secret USA hero association known as "the mystical order of supremacy." She acknowledged Xentra as a worthy adversary, more so than her mother Tetra.
Over the years, Xentra has achieved amazing feats, saving the universe side by side with the mystical order of supremacy. Xentra has done the unthinkable, overpowering a cosmic being, defeating intergalactic threats all by herself, restoring the universe with her reality powers, and breaking time and space with her immense speed. She even traveled back in time to stop herself from making the wrong decision and fought thousands of evil clones of herself that were powerful enough to shatter the multiverse. Xentra has killed cosmic beings and deities and is considered one of the most powerful beings in the multiverse, acknowledged even by deities for her capabilities.
Xentra has survived a super cosmic bomb powerful enough to destroy abstract entities and gods and avenged her mother by defeating the remaining tetronians who came to Earth and annihilated her loved ones. Despite possessing limited ability to gain other abilities from her kills, she is definitely powerful enough to hold her own. Xentra can break through dimensions with her immense speed, flight, and abilities, passing through ten dimensions and making it back to Earth in time to stop alien invasions.
Furthermore, Xentra has held mini black holes, contained twelve H1821+643 black holes that could consume thirty million solar masses each, escaped a Holmberg 158 black hole capable of containing ten million solar masses, and closed an NGC 1277 black hole (5,000,000,000 solar masses) located in the Perseus cluster, accounting for 5% of the mass in its host galaxy.
"Even Swiftie, a speedster, has acknowledged Xentra to be almost on par with her in her weakest state of speed. And Swiftie is fast enough to change the Earth's axis, traverse worlds, and dimensions in nanoseconds – fast enough to keep up with Xentra in terms of power.
Author's Note: Despite Xentra being powerful and fast, she's unable to outrun Swiftie at her normal pacing speed. Swiftie tries her best to maintain her velocity under control so as not to disrupt the timeline continuum. Swiftie is almost on par with true instant teleportation.
Xentra is also capable of recreating the universe. Even Ra'bby, her biological Xentorian father, acknowledges Xentra to be more powerful than him. He sees Xentra as a balance of all races, powerful enough to tap into her other hidden abilities.
One day, while Xentra was with her family, all enjoying the weekend, they all felt something from their backyard and realized that they had a guest. They all went out and were surprised to see a Tetronian male figure outside. Immediately, Tetra recognized him to be Tetron, his half-brother, whom her mother Tetrix talked about years ago.
"Hello, sister," Tetron said.
They all went inside as Tetron had a lot to discuss. He was sorry for not being there when he was needed the most, apologized for the death of their mother Tetrix, and was also happy for his sister Tetra's newfound happiness.
Tetron's arrival was to inform them of the impending doom and that he was gathering allies to fight side by side with other heroes against the coming threat. He also informed them that all of creation would be experiencing great devastation, and he warned them about the coming of the banished ones. Tetron didn't stay long, but he was very happy to see his sister and his niece Xentra.
Xentra still needed to know more about Planet Tetron, Xenda, and the Xentronian race, but Tetron assured her that he had been keeping an eye on them ever since their mother Tetrix came to Earth.
During their moment of discussion, something entered Earth's atmosphere at great speed. Tetron was able to fly over and maneuver the object from crashing against a building in a farm field and causing collateral damage, while Xentra followed from behind. After Tetron successfully landed the object in an open farm field, they found out it was an alien spaceship that had transported a baby alien to Earth. Tetron used his Tetra vision and was able to spot the planet's destruction from which the baby alien came.
The alien spaceship had an alien language inscription, which Tetron and Xentra understood perfectly. They were also able to spot a hidden codex inside the alien baby which they had rescued and found. On the alien spaceship, they saw a symbol like a shield imprinted with an "S" symbol, which Tetron recognized as an alien race originating from the deceased planet.
Xentra took the child, caring for it like a mother, as the alien baby was full of joy. They were also aware of the baby's ability to fly, shoot lasers from its eyes, and have super strength. Xentra wanted to keep the baby to herself, but Tetron advised her that the child wasn't their responsibility and that he was sent to Earth for a reason. He also told Xentra that the child would be a symbol of hope to humanity.
"This child is meant to be with this couple, to experience humanity and understand the good between both worlds," said Tetron. "You could keep an eye on him if you want. Xentra, guide him to the right path in understanding his abilities."
"But for now, he needs to be with this elderly couple who are yet to return from where they went," Tetron added as he used his Tetra beam to create on the ground a crash landing scene, making it look as if the spaceship had crash-landed. Xentra put the baby back into the spaceship and wrapped it with its blue and red blanket that had its symbol. As they left, the couples arrived, only to realize a strange object (a spaceship) with a baby in it, while Tetron and Xentra watched them from a far distance.
Tetron said his farewell to his people and went back to the place he came from, reassuring Xentra that their paths would eventually cross again."
