The timeline and series which it will have firstly some movies like justice league war or apocalypse for ben to meet and interact with the hero's then maybe some stories from comics then justice league unlimited then young justice along with teen titans.
The timeline might not be the same you have been warned, a few changes might be made because ben will be there in the story, not just the league so if you are here to see ben in the story and expecting everything to go the same way, then sorry, ben being in the dc universe will effect it, as for how much it'll be up to my mood.
Ben looked outside of the bus, he saw trees and beautiful sky unlike the city the air was fresh at the countryside they were only 15 minutes till he arrived at the station, then from there he will go to his friend's house.
Ben got down from the bus and looked around and he saw an blue pickup truck. His friend was sitting on the passenger's seat.
"Hey man" ben smiled happily at him.
"Man you made it, I am telling you these 3 months will be the best of our life" he said excitedly.
Ben nodded he couldn't lie he was looking forward to the holidays he couldn't remember the last time when he went to an friend's house and someone didn't attack him or he didn't needed to save the planet Ben's luck in that regard was horrible.
"Let's hope so" ben said " I hope that your parents don't mind me though".
"Nah man its fine they are chill with it" he said.
ben nodded "so what will we do?" ben asked what they will be doing during there vacation.
"well there is not much to see here i men it an small town but on the upside since there aren't that many people then we can be as loud as we want not to mention the fields are good for playing sports without worrying about breaking the windows of other people" they both cringed remembering about all the times they had broken at the windows.
"yeah that's good".
Soon his house came in view which had an good homely feeling to it it was an two story tall house.
Ben got off the truck with his backpack and entered with josh lock who was his friend.
"so what are we doing today?" ben asked josh.
"well today we will be seeing the sight's which won't take much time cause well there is not much to see besides farm's".
Ben nodded "well lets go".
They went outside and saw the sceneries and it was not that bad place the old ben well 10-year-old him might be boarded but the matured ben just liked the peace and quiet.
Well if you have to fight people like ben had anyone would appreciate some peace and quiet, they hung out with ben being a little happier than he was when he spent time with his current parents.
The next day.
Ben woke up and took a shower and went for a run thinking about his life paradox said that this world will face a threat that even ben couldn't face alone, and that alone was danger something that even ben couldn't face and ben had faced many foes from strength to crush planets in their fists to intelligent enough to destroy the universe.
"whatever for now I'll just take things slowly it'll have to show itself sooner or later" ben thought "and wen it does I'll destroy it".
For now I just need to take things slowly.
Half an hour later ben stopped outside a house and drank some water, and went under the shade of a tree to rest, ben looked around and saw that his friend's house was a few houses away.
Ben closed his eyes for a few minutes and concentrated in his heartbeat. It helped him in remembering that he was just a normal kid ever since the omnitrix mutated him by enhancing all of his physical abilities while ben didn't like them there was one ability that ben really liked- it was stamina he had nearly limitless stamina which meant that he could do hero work for months and not get tired, ben had yet to see the limits of his stamina because he still went to sleep for the sake of the feeling of sleep and dreams.
Ben opened his eyes and looked at the house in front of him he was a dozen meter's way but due to enhanced vision he could see everything clearly there was an old couple a man with black hairs and wearing glasses, had blue eyes ben looked at the second floor and saw a girl about the same age as ben, she was blond.
Ben didn't realised that he was staring at the family, soon the girl came down rubbing her eyes, when she opened them ben saw that they were blue. And somehow she was staring right at him, ben felt like she had noticed him, she was staring ben in the eye but that was impossible since ben would be only a dot to her.
Ben hesitantly raised his arm and gave a little wave.
It appeared that she could see him as her eyes widened. Being that ben acted like he was waving someone to his side and walked out from her field of vision.
Ben held his breath, that was close, how did she saw him ben thought with narrowed eyes no it was impossible for her to see him, she might be waving to her dog, ben did saw a dog, at the front door of there house.
At the house of the family,
The blond girl still had her hand held up she was still a bit shocked how could someone see her from that far.
On no she waved back at him, could he have realised that she could see him, he definitely did.
Wait he was not looking at her but to the side it looked like that he was waving to someelse to his left so maybe he didn't saw her.
"dear, everything ok?" her adoptive mother asked her, she realised that she still had her hand raised.
"oh" she blinked "nothing, everything's ok"
"ok" see smiled "then come on the food's getting cold".
She nodded, the food was well different from her home but not bad, to het it was the onlt thing good about this place.
She picked up the spoon but accidently broke it.
She looked at her adoptive mom "sorry, I am still getting used to it".
"don't worry about it" she waved her hands like it was normal "you wouldn't believe how many spoons Clark had broken".
She nodded, at least the people were nice.
With ben he was just getting out of the bath and saw that josh was sitting reading superman comic.
Ben walked to the bed to rest a bit.
'who was that girl?".
"meow!".
"meow!".
"MEOW!".
Ben opened his eyes and saw a cat in front him.
It was a black cat with blue eyes.
"it's you!" ben said surprised "how are you here?".
It was the same cat that he played with every day.
"meow" he pointed to his bag.
"so you snuck with me?".
"meow!" she said.
"well ok, let's go, I'll tell them not to bother you".
