KEN
Ken is one of the kids who was adopted into the family who doesn't consider himself one of day's kids. Along with his sister.
He and his sister lived with their parents, who on the bad parents scale were around Kioku's range, until one day there was an incident with one of his transformations, which caused him to attack his sister. Which is when D.O.C. took him and his sister.
Ken is similar to Kiba, but less cringe. He put up an arrogant act to hide his insecurities, when in reality he kinda hates himself for attacking his sister. Even if he didn't have full control.
While he can seem kind, rude and unpleasant, he can show his nice side if you let him.
Just don't feed his fragile ego.
Ken's quirk is called Omni. And it allows him to transform into 10 different forms, all with different powers, but he can only stay in one form for 10 minutes. Ken used to have some issues controlling when and what he'd transform into, until D.O.C. actually did something useful besides being a delivery service, and gave him a special watch called the Omnitrix, which allows him to to select and transform on the watch, and turn it into. Although it's not perfect, and they can still mistransform sometimes.
It seems like when Ken transforms, he can't go into another form until he turns back and waits ten minutes, but that might just be a limit they have right now. Due to an incident, Nara was forced to go from one transformation to another, so it's possible they could learn how to do it at will.
UPGRADE
Upgrade is one of Ken's transformations.
In this form, Ken becomes a living pile of goo, like Kyosei, and also like Kyosei, he can bond to things. But not people or animals, instead he bonds with technology.
When Upgrade bonds with something, he not only gets full control of it, but he can also change and upgrade it. Which is why the form is called Upgrade if you couldn't tell.
Even when not in this form, Upgrade can still do some basic shapeshifting, and shoot a laser out of its eye. Although it's not very strong.
Upgrade can also be used to program and reprogram things, at insane speeds. Which is why Ken uses this form to make video games.
Four Arms
Can you guess what's the main feature of this transformation? I'll give you a hint, it has something to do with its name.
Yeah, Four Arms is a big red guy with four arms and super strength. And that's it. It's a pretty simple form.
Wild Mutt
Wild Mutt(Ken's names for these forms don't get any better) is a giant orange dog monster with no eyes.
However instead of eyes, Wild Mutt uses his main power to see, smell. You know sonar, well Wild Mutt has that but with smell. He's great for tracking things down and finding things.
This form's not bad in combat either. It's pretty agile and strong, not as much as other forms, but more than most normal people. And he has super sharp claws.
STINKFLY
Stinkfly is a massive bug monster that smells like poop. So its name is accurate if still uncreative.
As you can guess, Stinkfly can fly, and his second ability is shooting weird sticky goop out of his four eye stalks. It's also very flammable.
Lastly, he has a very big tail that acts like a blade, and can cut through steel like a tin can.
Eyeguy
Eyeguy can create a bunch of eyes all over his body, which can shoot lasers. These lasers can burn or freeze things, and he can combine the eyes to make bigger, more powerful eyes.
Unfortunately, this form comes with a terrible price.
Some forms make minor changes to Ken or Nara's personality, and in this form, Ken makes Kei level eye puns.
It's more painful than any laser could ever be.
HEATBLAST
Heatblast can create and shoot out fire. As well as control any fire that he creates.
He can also absorb fire into his body, so he's actually great at putting out fires.
The fire's he can make are pretty strong, but not as strong as Endeavor, and especially Netsu.
FEEDBACK
Feedback can absorb, not just electricity, but any form of energy. Fire, lasers, electricity, light. So long as it's not a physical attack, he can absorb it though his fingers and weird head tentacles.
Although whenever he shoots it back out, it comes out as an electric attack.
So far the amount of energy he can absorb seems limitless.
BLITZWOLFER
Blitzwolfer for the most part is the same as Wildmutt, but with worse smell(still better than most) and eyes.
The main difference is that Blitzwolfer can shoot out a huge sonic attack from his mouth.
RIPJAWS
Ripjaws are giant fish, with a giant jaw.
Of course he can breathe underwater and swim really fast.
He also has a massive jaw with very sharp teeth that can bite into almost anything. Even Kiba at full power would find it painful to get bitten by them.
His bottom half can switch between a fish tail and legs, so he can go on land, but he has to be in water to breathe, so he's not very useful without it.
Lastly he also has claws, but compared to his jaw, they're nothing to write home about.
GHOSTFREAK
We've never seen Ghostfreak before. This is the form that made Ken attack his sister, and it's not available on the Omnitrix, because it makes him too aggressive.
Apparently he can pass through objects, but that's all we really know.
NARA
Nara is Ken's sister, and one of the few kids here to not be an O.P.C.
Unlike Ken, Nara doesn't have a form that makes her go berserk. But she didn't want to leave her brother, so D.O.C. just shrugged their shoulders and took her too. Which is weirdly nice of them.
Nara's one of the smarter people around, having some of the best grades in our classes, but she somehow has even last creativity then her brother, which leads to her struggling in fights sometimes.
She is generally pretty nice, although she can act like a smug know it all sometimes. And her ego is real unlike her brother.
Her quirk is the same as her brothers, only with different forms. Other than that, it works the exact same way.
GREYMATTER
Greymatter is super tiny. Like the size of an adult hand. So she's not super useful in battle like this.
However, this form is extremely smart. Smarter than anyone around here, except maybe the scientists.
She can understand advanced sciences, machines and biology with ease, and who knows what else.
CANNONBOLT
Cannonbolt is like an armadillo. She can roll up in her shell to make a giant wheel. And much like a wheel, she can roll around, moving at speeds faster than most cars, and hitting like an actual cannonball.
She also has claws, but they don't really come into play much.
XLR8
Is it just me or did Ken save all his good names for his sister?
XLR8 has insane speeds. Being the fastest person in the whole Midoriya Foundation. She's even faster than Kiba at full power.
However without her speed her attacks are pretty weak, so she needs to move around a lot to pack a punch.
She also has some claws, which can be really deadly when combined with her speed.
DIAMONDHEAD
I think Diamondhead is Nara's favorite form. And I can see why.
Diamondhead is a huge figure made out of crystals that look like, but aren't actually diamonds.
She can shape shift her arms however she likes, mostly using them to turn into swords, and she can shoot out sharp crystals.
Nara can even make diamonds erupt from the ground in pillars.
Also, being made of crystals, she can reflect lasers.
ARTICGUANA
Articgunna has only one ability, it can shoot out a beam from its mouth that'll freeze anything it touches.
DITTO
Ditto is pretty weak on their own, but they have the ability to split into a seemingly infinite number of clones.
However there is a big downside to this. Anything that happens to one of the clones, happens to the rest of them. Meaning if they get injured or killed, so do the rest of them. So Nara mostly uses this form for chores instead of battle.
HUMUNGOUSAUR
Humungosaur, is the strongest of both Ken and Nara's forms, being absolutely massive. They can even get even bigger and stronger, but it causes some strain on their body.
They're also really slow, and easy to hit.
BLOXX
So Bloxx is an ape made of legos. Which is somehow the weirdest of all their forms.
Bloxx can shape shift their body in any way they like. Extending their arms, turning into a wall, turning into a canon and shooting out parts of themselves.
They can also detect their body from anything they shapeshift into. So they can make a lego cage around someone, and then detach from it, and regrow their whole body.
By the way, these legos are not really legos. They're more like concrete than plastic.
WILDVINE
Wildvine is a plant. Their body is completely made of plants, and can shift and regenerate just as well as Bloxx. Although their body is way softer.
Wildvine can control planets around them, to do whatever Nara wants.
Lastly, Wildvine has weird black pods on her back, that they can pluck off, and throw, which will make them explode like bombs.
LODESTAR
Lodestar's body is made up of a bunch of small magnets, and a metal head. They can control any and all metal using their weird hands, and since their body is made of small magnets, if it's torn apart, she can put herself back together. Although the same can't be said for her head.
