Kuoh Academy
Ben had just discovered that Kiba, his first friend in Japan was a supernatural being known as a devil. Kiba wasn't only a devil he whole club was full of devils, even the club's president was a devil. Now Ben was on the run from Kiba and his clubmates after they revealed themselves to him and tried to make him join them. Ben escaped them and was trying to leave the school grounds as fast as he could before they could stop him.
"Come on, need to go quicker" Ben said to himself as he continued to run
Normally Ben would stay and fight, he had defeated the group of fallen angels but these were devils that he was dealing with and they outnumbered him like the fallen angels. Ben hadn't dealt with devils before and didn't know what he could do to stop them. As Ben continued to run a bolt of lightning came down from the sky and almost hit him.
"Ben, stop right there" a voice said
Ben turned around and saw Kiba walking up to him along with the other devils of the occult research club
"Let us talk this through Ben, we don't want to hurt you" Asia said pleading to Ben
"You guys sure are doing such a good job at showing it" Ben said lifting up the omnitrix
"Please put up a fight, I've wanted to kick your ass since the first day I met you" Issei said with a grin
"Remember Issei, Rias ordered us to bring him back unharmed" Kiba said to Issei
"She didn't say anything about not using force if he resisted" Issei replied
"Perv does have a point" the girl with white hair said popping her knuckles
"See, even Koneko agrees with me that we should rough him up" Issei said
"Don't let it go to your head" Koneko replied
"I know Rias asked us to settle this peacefully but I don't mind breaking the rules and getting a bit naughty" Akeno said in a seductive voice
That freaked Ben out just a little bit and made him back away slowly from them. It looked like they wanted a fight even though they were told bring him back peacefully. If that was the case then Ben was going to happily oblige.
"If it is a fight you want then it is a fight that you'll get" Ben said activating the omnitrix
As Ben hit the core of the omnitrix down, Koneko charged at him first ready to attack. As the green light engulfed Ben, Koneko threw a punch at him. Suddenly a large gloved fist with a single black claw on it grabbed Koneko's punch. It was revealed that Ben had transformed into a large orange bipedal tiger like creature that didn't have a tail. It wore black gloves that had green lining along with black pants that green boots and a green belt that had the omnitrix badge on it.

"Looks like someone just tried to attack Rath" Ben said lifting Koneko up to his face
"Down kitty" Koneko said kicking Ben in the face which caused him to drop her
Ben growled in anger as he stumbled backwards from the kick
"Let me tell you something Koneko, little girl that just kicked Rath in the face, kicking Rath in the face doesn't do you any favors getting on Rath's good side" Ben said
"Like I care" Koneko replied charging at Ben ready to attack once more
This time as Koneko went to attack Ben. Ben slammed both his fists down which caused Koneko to jump back. When she did that Ben grabbed her leg and slammed her down on the ground a few times.
"For the touchdown" Ben said as he threw Koneko like a football
Koneko crashed into the ground and was slow to get up, as she tried to go to attack, Kiba stopped her
"Careful guys we need to approach this differently" Kiba said to Koneko and the others
"Whatever Kiba, I'm kicking this guy's ass" Issei said as he charged at Ben at full speed
Issei went to use his sacred gear to attack Ben but Ben jumped over him and grabbed him by the collar of his uniform
"I think its time that Rath taught you a few manners, Issei Hyoudou, annoying class pervert who said gross things about my cousin" Ben told Issei
"HEEEEEY!!!" Issei said in a loud voice
"He's got you there perv" Koneko said
"Whatever, hey, who's side are you on anyways?" Issei said asking Koneko a question
Ben then lifted Issei up in the air and hit him with an uppercut
"Incursion Ambassador" Ben said
Ben then jumped up and grabbed Issei in the air and wrapped his arms and legs around him
"Polaris Pile Driver" Ben said as he came crashing down with Issei who hit the ground head first
"Man, my head is spinning" Issei said as he slowly got up
"Anterian Arm Bar" Ben said unleashing his next move on Issei
Issei was slow to get up from that one but Ben picked him up
" And now, Sirius Butt Kicking" Ben said unleashing one last move on Issei
Ben walked over to Issei and picked his head up
"Hey um, was that serious as in its important or Sirius the star?" Issei asked Ben
"THE STAR!!!" Ben answered yelling
"That's what I thought you meant" Issei said before passing out
With Issei down, all that was left was Kiba, Koneko and Akeno, Ben knew that poor Asia wasn't going to put up a fight. Koneko was going back to fight again but Kiba tried to stop her
"Don't Koneko, he already beat you and plus he already took down Issei" Kiba told her
"I don't care, beating the perv is easy, I'm going to put this kitty down" Koneko replied
"Ooh, I think I'm going to join you" Akeno said stepping forwards
"Fine, more the merrier, but Rath is going to warn you, you just bit off an eye that is bigger then your stomach can chew" Ben told the two of them
"That doesn't make any sense" Koneko said
"I KNOW!!!" Ben replied yelling angrily
Koneko then charged at Ben as Akeno threw lightning bolts at him which wouldn't be able to be blocked. As the lightning bolt hit Ben in the face, Koneko punched Ben in the gut multiple times. When she went to hit him once more, Ben grabbed both of her arms then her waist and snarled at her.
"Ophiuchus Suplex" Ben said as he unleashed a devastating move on Koneko
As Koneko slowly got up, Ben hit her with another Ophiuchus suplex knocking her out for good. Now all that was left was Kiba and Akeno since Asia wasn't going to fight
"Is that the best you devils got because Rath can take on a lot more" Ben said pointing at the devils
Akeno and Kiba looked at each other then at Asia
"Asia, you go and heal Koneko and Issei, I know Ben won't attack you but I'll stay back and make sure" Kiba told Asia
"Looks like its just you and mean kitten" Akeno said licking her lips while making a purring sound
"Rath is not a kitten but geesh, you really freak Rath out lady" Ben said grossed out
Akeno giggled as electricity crackled around her fingertips
"Time for some fun" Akeno said
Rath charged at Akeno and went to punch her but Akeno flew above him and zapped him in the head with her electricit
"You gotta do better then that if you want to beat Rath" Ben said
"Oh trust me cutie, I can do a whole lot better" Akeno replied seductively
Ben as Rath shuddered a bit seeing Akeno do that
"Your creeping Rath out" Ben said
Akeno giggled and threw a flurry of lightning bolts at Ben while Ben charged at her. The bolts of lightning didn't effect Ben which allowed him to grab Akeno by the arm and slam her down into the ground before punching her again and again.
"Hit me harder big boy" Akeno said as Ben punched her in the gut
Ben then began to slow down on the punching before stopping as Akeno moaned with each punch
"Okay creepy lady, Rath is just done with you" Ben said
"That's no fun, I thought you were gonna play with me" Akeno said pouting
"Let me tell you something Akeno, creepy lady who moans as Rath punches her, its not fun when you make things weird" Ben said before walking away from Akeno
"No one turns their back on me" Akeno said floating in the air
Suddenly Akeno hit Ben in the back of his head with a large bolt of lightning. The lightning didn't do anything to Ben except singe the back of his head. Ben slowly turned around and faced Akeno with a glare on his face.
"Let me tell you something Akeno, creepy girl who keeps weirding Rath out, Rath was gonna be nice and give you a chance to leave but now you just made a mistake, shooting Rath in the back of the head doesn't do anything except make Rath more MAD!!!" Ben said yelling that last part
Akeno gulped a bit before Ben jumped into the air and landed down on her. Before she could attack, Ben began to punch her over and over before finally throwing Akeno into a tree. As Ben was about to show off, Kiba charged at him and tried to hit Ben with a sword. Ben as Rath quickly reacted and flipped over Kiba, avoiding his attack.
"Let me tell you something Kiba Yuto, once good friend of mine, you've got this beat down coming for betraying Rath's trust" Ben said with a low growl
"Ben it isn't like that, I didn't want any of this to happen" Kiba said
"Rath doesn't care about your excuses and lies, just fight Rath already" Ben replied extending his claws
Kiba sighed and formed another sword in his other hand before charging at Ben. As Kiba swung one sword down, Ben blocked by putting his arms up. Kiba swung the other sword but Ben caught it in his mouth and snapped the blade of the sword in half. Kiba tried to pull back but Ben grabbed his head and kneed him in the face. Ben then threw Kiba into a tree before backing up slowly. Ben then ran at Kiba who was slow to get up, Ben would then jump into the air above Kiba.
"Sheer Cosmic Drop" Ben yelled as he came down on Kiba
Kiba tried to roll out of the way but was unable to avoid Ben's attack. As Ben got up off of Kiba, he grabbed Kiba by the leg and lifted him up.
"After this is over, never talk to Rath AGAIN!!!" Ben yelled at Kiba with a loud roar before he threw him away
With everyone but Asia defeated Ben felt as though he was done
"Rath won't hurt you little Asia but you tell Rias to leave Rath alone, his soul is his own" Rath told Asia before walking away
"I'll make note of that" a voice said
Ben turned around and saw Rias standing there next to Asia
"You want some of Rath too?" Ben asked getting into a stance
Rias looked around and saw that Ben had defeated all of her peerage
"I told them to not use violence" Rias said with a sigh
"Maybe you should get new slaves" Ben suggested
"They aren't slaves, they are my peerage, my family" Rias replied
"Sure looks like that from where I'm standing" Ben said sarcastically with his arms crossed
That angered Rias, hearing someone say that about her peerage
"Listen Benjamin, I will only give you one more chance to end this and come with me peacefully" Rias told Ben
"Let Rath think about that for a minute…how about no" Ben said
"Fine then, you leave me with no choice, I won't force you to join us but I will get revenge for what you've done to my peerage" Rias said as she formed a magic circle around her hand
Ben grinned hearing Rias say that
"Finally, Rath has been waiting for a good fight" Ben said popping his knuckles
Ben then ran straight for Rias, Rias used her destruction magic to push Ben back. That didn't stop Ben, he went to attack her again but Rias used her destruction magic one more time. This time Ben was planted into the ground and pushed back even more.
"Let…me…tell you…something" Ben said as he slowly got out of the crater his body created
Before Ben could get all the way out, Rias hit him one more time with her magic pushing Ben down even deeper into the ground. Rias walked over to the crater and looked down and saw Ben laying there.
"And to think that I had high hopes for you" Rias said before she walked away
Suddenly a flash of green light caught Rias's attention, she turned around and looked back into the crater. As she did that a sonic wave hit her and sent her back. As Rias got up slowly she saw a gray little robot looking thing jump out of the hole. This robot wore what looked headphones and didn't have any eyes or a nose. This was Ben's Sonorosian form he called Echo Echo.
"You are just full of surprises Benjamin" Rias said as she fixed her hair
"You…have…no idea" Ben said in a robotic voice
With that Rias readied her magic and went to attack Ben once more. As Rias's magic came at Ben, Ben unleashed a sonic attack and somehow stopped the magic from hitting him. Rias was surprised to see that happen but she was even more surprised to see Ben clone himself.
"Clone yourself as many times as you want, it doesn't matter to me" Rias said
"You know" one clone started
"It didn't" a second clone continue
"Have to" a third clone also continued
"Be…this…way" a fourth clone finished
"I know but it looks like there wasn't any other way this could of gone" Rias replied
"Sorry…for…this" Ben said
"I am sorry" Rias said before unleashing a wave of destruction magic that destroyed a few of Ben's Echo clones
Ben cloned himself a few more times before unleashing an attack
"Wall…Of…Sound!!!" Ben yelled unleashing a strong sonic attack at Rias
Rias fell to her knees from the attack and tried to get up but was unable to do so. Seeing this, Ben turned up the attack before stopping.
"Don't…come…after…me" Ben said walking away as his clones merged back into his body
As Ben walked away, Rias got up as her eyes began to glow crimson red
"I am Rias Gremory, member of the Gremory clan, my brother is Sirzechs Lucifer, king of hell and I won't be defeated so easily" Rias said
Ben turned around and saw Rias throw a bolt of crimson energy at him, as the bolt hit him, Ben cloned himself before his body was destroyed. Rias now had the upper hand in this fight, every time Ben tried to attack her, Rias would stop him. She kept destroying his echoes as he created them to avoid her attacks.
"Things" one clone began
"Aren't looking" a second clone continue
"So good" a third clone finished
"You will submit to me now" Rias said as the crimson energy float all around her body
"You know…what…they say…when…going hero…doesn't work…you can…always…go…Ultimate" Ben said
Ben then merged with his echoes before twisting the omnitrix badge before hitting once more. A light green light washed over Ben in his Echo Echo form. Echo Echo, got taller and looked even more like a robot, he became blue and had discs all over his body. The omnitrix symbol was on his chest and had four prongs sticking out of it.
https/insane-mane/art/OV-Ultimate-Echo-Echo-813786791
"Ultimate Echo Echo " Ben said in his ultimate form
"Regardless of the forms you take, you won't beat me" Rias said
"We'll see about that " Ben said
Rias went to attack Ben but Ben lifted his arms up and hit Rias with an even stronger sonic attack. Rias was caught off guard by that and tried to get up before Ben hit her once more. Once Rias was on the ground and couldn't get up Ben lowered his arms.
"Stay down, now, I won't warn you again " Ben told Rias
"You'll have to kill me, I won't let those who hurt my peerage get away with it" Rias said as she got up off the ground
"Here's something you should know about me, I'm a hero, I don't kill my enemies, I take them down, not out " Ben told Rias
"Good to know" Rias said as she charged up an attack and sent it at Ben
Ben was quick to react and sent his floating discs and had them surround the attack before using a sonic attack to contain it. Once the spell dissipated, Ben had the discs stop and return back to him. Seeing that there wasn't going to be any end to this unless one of then couldn't fight any longer.
"There won't be an end to this so it looks like I'll have to be a bit more forceful " Ben said before sending his discs at Rias
Rias got into a defensive stance and was waiting for Ben to attack her. Ben let out a sigh before he unleashed an attack
"Sonic DOOM!!!" Ben yelled unleashing one of his strongest attacks on Rias
The attack hit Rias from all over and caused her to fall to the ground and close her eyes. Seeing that Rias was down, Ben stopped the attack, he then sent one of his discs over Rias's body.
"Still has a pulse, good, hopefully they'll leave me alone from now on " Ben said as his disc returned to his body
With that Ben transformed back to normal Echo Echo before transforming back into himself. With this opportunity Ben grabbed his bag and ran all the way home as fast as he could.
Time Skip
Ben's Apartment
Ben had finally made it all the way to his apartment, as he quickly opened the door he got in and closed it even quicker. Ben locked the door and made sure that no one had followed him home. Ben may of won against Rias and the other devils but he didn't know if they'd come back for him with even more devils.
"What is with all of the panic Benjamin?" A voice asked Ben
"You'd be in a panic too if some group of devils may come back for revenge against you" Ben answered
It took Ben a minute to figure out what was going on, he turned around and saw a familiar figure standing in his living room. It was professor Paradox and he was chewing on a gumball.
"Professor Paradox, it's you" Ben said surprised
"Of course it is me Benjamin, who else would it be, the Tooth Fairy?" Paradox asked with a laugh
"Paradox, I really need your help" Ben said
"I wouldn't worry about lady Rias and the others, there are far more important threats that you need to worry about" Paradox replied
"Wait, you know about all of that?" Ben asked confused
"I am a time walker, I know everything" Paradox answered
"Of course you know, hey wait a minute, you knew about all these devils and fallen angels?" Ben asked angered
"Benjamin my dear boy, there is a lot that we need to talk about" Paradox said
A/N: Alright, looks like Ben beat Rias and the others and now is going to have a long conversation with Paradox who has finally made himself known. I hope all you readers enjoyed the fight with Ben against the occult research club. Also I hope you enjoyed seeing Rath being Rath, I had fun writing this fight scene. Now, you've seen another ultimate form and this time it is ultimate Echo Echo. You will see more ultimate forms in future chapters and even more new ultimate forms. Oh, before I forget, this story is taking place before the rating game between Riser. So you'll be seeing Ben helping Rias and the others with all of that. Who knows, you might even see Ben throw down with Riser just a bit.
Now, I am going to be answering questions and respond to questions from the last chapter. Maximum Rhapsody, I can't exactly answer that question without spoiling a few things. But I can say that a few key figures know about it and know what Ben has done, they just don't know what he looks like. When it comes to doing a DC/Marvel/Ben 10 crossover, I had thought about doing something like it but I just didn't know how I would start it, which continuities I'd use and how it would go. Zero-Nightmare, none of Ben's villains are responsible for the fallen angel attack on Ben but there is someone who is, can't exactly say without spoiling things but it is a second plot line I have going.
With those questions answered, let's get to responding to comments from the last chapter. kratsbroth, I was waiting for that one as well and it took me awhile to get to it. Maximum Rhapsody, don't worry at this point I doubt that I will make a devil, you and every other reader has made their opinion known to me about that. When it comes to Ben 10 villains coming to Japan, I wouldn't exactly worry about that, I'm kind of keeping the spotlight on Ben and just Ben being in Japan, so none of his villains will be appearing in the story, only in mentions and callbacks. Bromega2477, you better be adding some butter to that popcorn.
Th3Gr3atestSyl4r, sorry but Ravel isn't in the duo love interest, you're a little late on the vote and hardly anyone wanted to see her in the first place. Zero-Nightmare, thanks for that and you have made a lot of good points, I can't exactly reply to all of them but, I will be thinking a lot about what you said. Lionsleeps, I wouldn't exactly be worrying about that at this point. TeenBenIsGreat, like I've been saying throughout this whole time, Ben is not going to be a devil so hopefully people will stop asking me about that. Ben will help them out without joining their peerage, who knows he might become an honorary devil or something like that. I've made Ben as strong as I could in this story so he'll be able to give some devils and gods a run for their money.
Guest-Questioner, thank you for that long reminder, I and a few others didn't see the need or point of it but you do you and trust me they learned something. Argofuckyourself, I hate to tell you this but you're the only one who thinks that about this story. If you don't want to read another DxD crossover then don't read one. That doesn't mean be an asshole and give me your garbage take on a story your not going to read. Go be a beta on Reddit or Discord not on here and not with me. With that off my chest now, Lordhavemercy, don't worry Ben won't be a devil but that doesn't mean he won't be helping them out every now and then also I was thinking about doing that but I might not do it since there probably isn't any guy sports at Kuoh since they only recently became Coed.
With all of the comments responded to I am going to finish up now. Thank you for reading and for your support, I will be seeing you all later
