Rapi from Goddess of Victory Nikke: >! Rapi is a Cyborg supersoldier who can survive as long as her brain remains intact. During the beginning of the story, a monster cuts off her head, but the rest of the group manages to defeat it and escape alive, allowing her to recover when she is given a new body. But much later, the 4 beasts, a group of villains, find that severed body and use it as material to create a new Rapture Queen (the monsters of the game) and after combining it with dark matter (a material created with the blood of the old queen) and with the DNA of the commander (the main character) they manage to create the new queen, and she recognizes Rapi as her mother. !<

Ainz Ooal Gown from Overlord: Ains was a player in a virtual reality MMORPG. Within this game, he was the leader of one of the largest guilds, composed of players of monstrous races. In his case, he was an "Overlord," the most advanced form of Lich. One of the game's unique features was the ability to create NPCs for the guild. Each player created a few, but Ains only created one: "Pandora's Actor," a doppelganger programmed to act embarrassingly. However, when he was transported to another world along with all the other NPCs, they gained consciousness, considering the player who created them as their father. In this case, Pandora's Actor became Ains's son.

Rimuru Tempest from That Time I Got Reincarnated as a Slime: Rimuru was a human who reincarnated as a slime in a fantasy world. He eventually created a nation of monsters and became its leader. In the Isekai Memories video game, a slime girl appears who claims to be Rimuru's daughter, but it is later revealed that she is a female clone of Rimuru created when someone wished for a cuter version of him.

In Ben 10, the Omnitrix is an alien device capable of transforming its user into the peak version of a species—free of genetic defects and highlighting that species’ best traits. Throughout the series we see many alien transformations, but never a human one, since the user (Ben) is already human and the Omnitrix doesn’t allow transforming into your own species.

But what if an alien had received the Omnitrix instead of Ben and transformed into a human? (Albedo doesn’t count, since his Omnitrix malfunctioned and turned him into a copy of Ben.)

To answer this, we need to look at what traits humans value in our society, as well as what makes us stand out compared to other species in the Ben 10 universe.

Endurance: Humans are one of the most endurance-oriented species on Earth. We were persistence hunters in the past, and that trait still exists today. Compared to most animals, humans would excel in something like long-distance running or marathons.
Intelligence: While humans are the most intelligent species on Earth, that’s not the case in Ben 10, where species like the Galvans exist—whose average member is a genius compared to a human. Even so, a “human alien” should still have enhanced intelligence (though below Galvan level), since it’s a key trait we value.
Adaptability: One of humanity’s defining traits. Humans have adapted to nearly every environment—from extreme cold to deserts—and managed to thrive. In an alien-human form, this could translate into exceptional improvisation skills and the ability to quickly adapt to unexpected situations.
Tool Use: Individually, humans are relatively weak, but we’ve dominated our planet through tools and technology. This also applies in Ben 10, where groups like the Forever Knights can defeat much stronger aliens using advanced tech. This could tie into adaptability, giving the human alien proficiency with all kinds of weapons and equipment.
Art: This one is more debatable, but art is present in nearly every human society. So, this alien might have strong creative or artistic abilities across different fields.
Strength: Many Ben 10 aliens far surpass humans in raw strength. Still, a human at their peak would be fairly strong—comparable to an Olympic athlete. The closest comparison would be Captain America (though slightly weaker), or in Ben 10 terms, something like Bullfrag—but weaker in unarmed combat due to lacking his jumping ability and extendable tongue.
Leadership: This is likely where the human alien would stand out the most. Humans are inherently social creatures—we’ve always relied on cooperation, from the past hunting in groups to our modern complex societies. Leadership is highly valued because we depend on teamwork and diplomacy. This also applies in Ben 10: humans are one of the few species that use democracy, while many others rely on monarchies or meritocracies. Many notable humans in the series demonstrate this trait, like Grandpa Max, one of the best Plumbers in the galaxy, even chosen by Azmuth to wield the Omnitrix.

Conclusion:
This human alien would be physically comparable to Captain America but slightly weaker. It could fight at the level of Bullfrag—or slightly better if equipped with a good weapon—but would be worse in unarmed combat.

It would be the ideal transformation in situations like:

Leading a military organization like the Plumbers on a mission
Performing long-duration tasks requiring both physical and mental endurance
Handling diplomacy between multiple conflicting species
Or even improvising in something like a talent contest
