This series is a crossover between The 100 and Ultimate Man crossover meaning it's a Justice League and Ben 10 is in Ultimate Man. The oc is Wonder Woman and Ben ice user son and the youngest Amazon prince. So actually it is a three-way crossover.

The reason why I put Ben. T hear instead of the JL because there isint a crossover between them and sorry if you guys suspected Ben to hear I was thinking about it but been is just my overpowered and if there is an Author out there that is reading you can make your own Ben T and 100 crossovers.

The fanfics I make are all connected to Ultimate Man fanfictions and I will make lots of Ultimate Man fanfics and Crossover and if you haven't read Ultimate Man before I advise you too.

Warning this oc is overpowered in this story and can defeat the likes of Atomix, Ultimate Humangosour, Ultimate Swampfire, and Waybig.

Now you may ask who this person and why is he floating in space. He is the son of Diana Prince known as Wonder Woman and Ben Tennyson who is known as Ultimate Man. His name is Ken. Where he comes from he is known as the famous Ice user. One of the strongest Warriors in the universe. The youngest Amazon Prince. The grandson of Thunder God Zeus. The ice Demon. The God of Ice and water. He is Ken prince Tennyson.

You all are wondering how he and up to hear well the reason for him floating in space is what happened a few hours ago. Ken and the rest of of of his family defended Earth from Trigon and his army of demons with the help of the Green Lanterns and Plumbers and some superheroes.

Trigon came out of a portal with his army wanting the rule the universe and kill everybody. Trigon is a Universal treat. Trigon killed the Green Lanterns, Plumbers, and some of his family members especially his mother and sister, brother.

Ken, Ben, and his older brother were the last ones standing. Blood and bodies everywhere the sky was red. The father and sons look at the demon.

Trigon shot black lighting out of his palms at Zatanna. With instincts, his body runs and took the blast for her but it shot him in the heart. Ben falls to his knees as he saw that his son just died it hurt him it hurts him a lot. He lost his oldest twin daughter and his wives. The rest of his children is unconscious. Trigon laughs darkly and then shot a blue galaxy level energy blast towards Supergirl. Ken's heartbeat loudly and jumps in and blocks the blast with his bare hands. He has lost a lot of energy and stamina but he can block it but he is struggling.

Normally this wouldn't be a problem for him because at the age of 14 he was able to destroy a planet with his ice powers.

Ken covered his hands in ice so that he could counter but he feels Trigon putting much power in the blast. Now he knows that Trigon is struggling hope begins to fill his heart. An idea begins to form in his head as he told Supergirl about a ritual that Kryptonians can do. This ritual lets her species merged into one being. So he told her that she should trust him. It took some time for her but eventually, she came around and then spotted Foara and picks her up and Powergirl heard everything and looks for Galatea.

Ken knows his losing his strength show he looks around the dead bodies, his father that is over at his oldest Amazon son and Ken smiles at that he looks then at the female Kryptonians who are preparing to do the ritual. He then looks at his other siblings including his stepmothers and stepbrothers and stepSisters. After that, he looks at his mother's dead body and younger Amazon sister that is still breathing but unconscious his eyes trailed off to his cousins, uncles and aunts.

He chuckles and told himself am going out as threw warrior and then he yelled ice cannon. Ice came out of both his hands and is starting to push trigon blast back. Trigon got made and roared overpowered Ken's ice blast. Ken cried out loudly as his body is overcome by a bright big blue blast.

Ben and everyone conscious saw this. The girls are done with their fusion and Ben told them to fuse again. Kara fused with Foara and Karen is known as power girl fused with Galatea they all saw their mate. Their boyfriend got killed by Trigon the two fusion Kryptonians could feel rage running throw their blood but Ben snapped them out of it believing that the two isint strong enough to defeat him. He told them to it again this time as a fusion while Ben covering for them.

They nod and do it again Ben stand up and yelled loudly in rage. Yellow aura burst around Ben his hair turns golden hair spiky. His eyes disappear

and the blue aura is in the middle and the yellow aura is above it. Ben tail is golden and yelled you are going to pay Trigon for killing my family. He rushed over to him and the battle between them only continue as this is the 4 round they been fighting.

The first round with Ultimate Chromastone, Ultimate Waybig, and Atomix, the second with stage 2 Atomix (Fan-made form of mine only Ultimate Man fans would understand), The third round with Big Chill (Stage 1 form and Demon form), Fourth round Shallot SsjGod Ssjblue and now his new transformation Ssjrage.

The battle goes in they have been fighting for 10 minutes as ben is losing because of blind rage. The Kryptonian's fusions have merged into one now four Kryptonians merge into one body but there is a side effect meaning they will be stuck as a fusion for a couple of years.

Ben got knocked out cold out of his Saiyan transformation. His hair turns normal and a green light overcame his body as he returns to his human ultimate form giving Ben the ability to have his aliens powers without transforming into them. So basically Ben uses aliens' powers in his human form and every time he transforms his appearance change into a human version of his aliens.

Now the fusion Kryptonian battling with the demon as ben search for Alien x and wondering why he couldn't find Alien X in his library. Eventually, he finds the alien pushed the fusion out of the way hit Trigon in the face sending him into the solar system and hammer punch him back to earth making a huge crater but he didn't punch with all his mind because the Earth would have been destroyed. Ben landed on earth finding Trigon wanting to escape into a portal but Ben blast a universal blast to Trigon pushing him into the portal and once he was in there he a huge explosion corrupted. Now ben is wondering did he killed Trigon or did he survive. In a Green flash, ben transform out of Alien X not by choice because he was too tired and then something happened Ben died.

Universe unknownOmni multiverseCreator: Alien XSibling universe: Titan universe ( Known as the home of Eren Yeager ally to the Omni force Next generation)

now we find Ken in an alternate universe slowly suffocating in space. Shortly after he appeared in this universe after he was supposed to die from Trigon blast. He is currently unconscious, he didn't have to worry about freezing to death as he is immune to cold to him it feels like bathing in a spa. He has also had Space Survivability thanks to the powers he got from Big Chill.

While Ken was drifting in space some people from this universe observed him and were surprised because they saw him appear in a bright flash. These people were located in the observation room of the arc also used as a command center.

The appearance of Ken caused a great panic at first, though chancellor Jaha quickly calmed the people down in order to determine the situation. The chancellor presented the 2 choices they had. First, they could ignore whoever it is that's drifting out there and carry on with their plans to send the 100 prisoners down to earth in a few days' time or they could investigate the appearance of this unknown person. Most of the council voted for Jaha to decide what he thinks is best while the police chief expressed his concerns about letting an unknown possibly dangerous person or alien enter the arc dead or not.

Jaha asked for the opinion of the arcs doctor and she told him that there is great promise in salvaging the person for example they may be able to find out how he suddenly appeared and use this technology for themselves. Jaha agreed and ordered for one of the mechanics to go out in a suit and bring him onto the space station.

After Ken was brought on board he was checked for dangerous substances and then brought to the arcs medic bay to determine if he's human. All the while they failed to notice the almost none existing pulse of Ken slowly increasing. Abby got a huge scare when she examined him, was about to cut him open to do an autopsy and he suddenly started breathing. She immediately checked his overall health and send a helper to fetch Jaha and Marcus asap. A few minutes later she told them the situation Ken is in, which was that he is unconscious and suffered various wounds which were rapidly starting to heal she also told them that he has similar genetics to humans nitely not entirely human she assumed him to be a mutation or an Alien but she pushed last that thought I mean how could an Alien look like a human. She saw Ken rapidly healing but regenerating. Ken has the ability to regenerate is his sleep fast if he lost lots of energy but if he is awake and needs to regenerate fast it could take some time. She saw something shocking his bruises are covered in ice all his injuries actually and as the ice disappears his injuries are gone. What is even more shocking is that his tattoos disappear from his body and his hair turned from raven to brunet brown.

Jaha decided to bring Ken into a prison cell transformed into a secured patient room until he wakes up and they can question and further investigate him.

And done the first-ever Ben. T crossover fanfic with the 100 is done. I just made history!!

Now I know some of you is made about not Ben being the MC. But all my fanfics are connected and if a writer is reading why not come up with your own Ben. T fanfic.

Now Ultimate Man fans The Trigon arc will come up in ben timeline-like 19 years into the future.

Ken was trained by, Ben, Wonder Woman, Paresodone water and ocean God, Artemis (Amazon,) and the Legendary Assasin Hit by the age of 8.

Necrofriggian inside of him but he can only control 60% of his power. if he goes further beyond he goes berserk.

Think about Goku or Vegeta ssj4 style but not with the furr. 71-80 He becomes more muscular, his hair turns snow white and his eyes turn icy blue. 80%-99 He becomes more muscular think about brolly LSS form. 100% (or known as full power) his hair becomes like ssj3 style and ice tattoos disappear along with his ice that is covered in his body.

So yes The demon that he sealed inside of him can only use 60% of North powers.

Paring? who should it be Clark or Octavia

and Ken is a badass oc. He doesn't talk like an Amazon because he was raised in Omnitrix City and he can act like one when he goes to paradise island. only his oldest sister can talk like that.
