Alexander: Why did father have all of us meet here?

Sarada: He said he had something important to do with us.

Amity: Uh...why is he here?

Mitsuki:*waves* Hello.

Luz: Moral... support?

Suddenly a portal opened in the middle of the room and a figure flew out of it and landed in front of everyone

Dominic: Ah. So you've all arrived.

Sarada: Papa!

Alexander: Father! Why did you tell us to be here? And why do you not have your coat on?

Dominic: It's quite simple really. I want you all...to fight me.

Amity: F-fight you!

Mitsuki: You want to test all of us. See how far we've come.

Dominic: Correct. You've defeated those who could be labeled as "superhuman" but you are still far from defeating beings of my caliber. Even when Nero was apart of that cult he was strong. You're all years behind that Nero. But now I'm here to test you all and evaluate your strength.

Luz: But what about Amity and me? We're just witches.

Dominic: Magic will only get you so far my dear. Your own wits and skills with your hands will help you survive.

Alexander: So are we fighting you one at a time or all at once?

Dominic: Do whatever it takes to win. Fight with the intent to kill me. But know this, you won't even get a chance to bruise me~

Sarada: Gh! We can do this guys! If we work together we can get at least one hit on him!

Alexander: Our strength alone won't help us. But I am my mother's son. So I always have a few aces up my sleeve.

Alexander reaches into his pocket and pulls out a red fruit

Mitsuki: What is that?

Alexander: This is fruit from the Tree of Might. It amplifies ones power for a while. It should give us the edge in fighting our father.

Sarada: But... wouldn't that be cheating? He wanted to see our own strength and eating that would be wrong.

Alexander: He said to attack with the intent to kill. Besides, father isn't above eating forbidden fruit to gain power over his rivals.

The image of Urizen holding the fruit of the Qlipoth in his hand flashes for a second as Alexander breaks off a few pieces of the fruit and hands them to everyone

Alexander: Don't be shocked by the power it gives you. Just stay calm and keep a clear mind.

Alexander was the first to consume his piece of the fruit and his power skyrockets. He begins growling as his hair grows out a bit and his teeth turn into fangs and he gets into a tiger like stance with a yellow aura exploding from his body

Sarada eats hers next and her sharingan activates and evolves immediately into it's third tomoe state and her jet black hair turns white and a purple aura surrounds her

Mitsuki was next and his piece brought him into Sage Mode immediately. The power he felt was like he could never grow tired or hungry

Luz and Amity ate their pieces and although they were just ordinary children with magic it benefited them by boosting their magical prowess to near master levels with both of them summoning a four armed abomination

Alexander: Now is the time....we fight!!

Dominic: Yes. Fight me! Do not run when the devil is staring you right into your soul. Run towards him shouting! Make him try to kill you! Show me the fire in your souls! Show me you are worthy of being called the heirs of Sparda! FIGHT!!

Dominic flew in towards the group of his children and they all charged at him. It was an all out battle. Four warriors against a demon king. A tale as old as time.

Mitsuki and Sarada both attack Dominic with a flurry of punches and kicks but the elder devil just blocks their punches while staring at them

Alexander appears behind Dominic and throws a kick at his head but his leg was grabbed by Dominic and he was used as a living weapon against Sarada and Mitsuki.

He was then throws into the air and punched in the gut by Dominic who them elbows him back down onto the hard metal floor. Dominic then lands on Alexander hard, snapping his back and using his body as a base for him to launch himself at Sarada and knee her in the chest making her cough up blood

Dominic: Ah my princess. It took a fruit to show everyone your true form. You truly are my spawn~

Sarada falls to the floor clutching her stomach and she doesn't see Dominic bringing his foot up and smashing her face into the floor

Dominic: Heh~

A quick gust of wind catches Dominic by surprise but when he catches an image of Mitsuki passing him he smiles and stands still

Dominic: Ah yes. I forget sage chakra amplifies everything in a person's body. Your senses, your strength. But too much of it and it will kill you. Luckily I don't have such weakness that I need to use that chakra. And besides-

Dominic strikes Mitsuki from behind which sends him flying across the floor

Dominic: I can see you just fine my son.

Mitsuki grunts as he tries to pick himself up off the floor

Dominic: Confused on how I saw you from behind? Well let me tell you a secret that you will all soon experience. We can see in the third person. Basically, imagine a third eye floating behind you at all times. It allows us to see our opponents coming from every direction. And on how I struck you so fast, well..I am me after all. I'm a big deal.

Mitsuki grunts and extends his arms out and wraps them around Dominic's legs holding him in place

Dominic: Oh?

A shadow looms over Dominic and he looks up to see the four armed abomination standing over him. It throws a punch down at him and sends smoke around the arena upon impact. Once the dust clears it reveals that Dominic had caught the abominations fist with one hand

Dominic: A good trick. But a trick is all it was.

Mitsuki: Not...done..yet!

Dominic: Hm?

Alexander came back running on all fours and with a loud roar he lunges at his father, spinning through the air

Alexander: Leo Vortex Crusher!!

Dominic: Rh!

Dominic pushed away the abomination and throws his hands forward, catching Alexander but his attack was still going and it begun to push Dominic back

Alexander: Sarada! Now!

Sarada came up from behind, her hand flowing with lightning release chakra along with her eyes glowing red as she ran towards her father at blinding speeds

Sarada: Chidori!!

Dominic catches Sarada's hand with his other arm and now he was trapped holding two of his children's attacks and Mitsuki holding him in place

Amity/ Luz: Haaa!!

Both witches bring the abomination together and remake it into a large wyvern and send it flying towards Dominic

Dominic: Oh no!

Dominic takes a look at his surroundings and sees nothing he can use to escape until he spots Sarada's hand. He smirks and summons his doppelganger which the uppercuts her in the face, disorienting her and giving Dominic the opportunity to use her hand to create seals to which he takes in a breath and shoots a ball of fire from his mouth at the wyvern abomination melting it

Dominic: Playtime is over, time to step it up! GAAAAAAAHH!!

Dominic shouts and his body explodes in a bright blue aura that sends everyone away from him

Dominic: Excellent work you all! I admit I was caught off guard by that attack. Sarada, if that Chidori had hit me it would have definitely hurt me. A plus for that. But now let's see if I can hurt you all to get you to transform. Besides Amity and Luz. Yet~

Dominic brings his hands together and flows his chakra into the ground beneath him

Dominic: Corrupted Wood Style! Qlipoth Infestation Jutsu!

Roots begin sprouting out of the ground and attacking the children causing them to go on the evasive as Dominic was carried above them by a bundle of roots

Dominic: Ha! Nidhogg Duplication!!

Out of the roots, came multiple grey humanoids with blades for arms and they rushed the children as Dominic stood on top of his makeshift tower

Dominic: Ah. A father bonding with his children. What more can anyone want?

Dominic created a chair made out of roots and sat on it waiting for his children to inevitably make it up to him. All he had to do was wait.
