(Y/N) and Ult.Brainstorm stood oppose to the newly named Ult.All Might who gave them a menacing grin. Ult.All Might then lets out a war cry and rushes towards the two. Ult.Brainstorm lifted one of his railgun like claws and fired out a couple of electrical blasts at him. In response a barrier appeared around him completely nullifying the blasts shocking Ult.Brainstorm. The shield then dropped once he made it to them and he punch Ult.Brainstorm away. (Y/N) slashed at him with her lance trying to hit him, only for him to dodge out of the way. (Y/N) continued to try to and slash him with him constantly dodging out of the way of them. He soon caught her lance shocking her and causing him to grin. He then struck her with a punch to her gut with her spitting up some saliva. He then quickly spun around and threw her away into a wall. Ult.All Might grinned at this before he heard something. He turned and caught another electrical blast from Ult.Brainstorm. Smiling at this he crushed it before he then disappeared and reappearing behind him. He grabbed him by his head and threw him up into the air and quickly appeared above him knocking him into ground below covering him with rubble. Ult.All Might laughed as he descended down to the ground.

Ult.All Might: How's that Mr. Hero, how's it feel to be put into the dirt

He suddenly felt something, and he dodged out of the way of a ball of light magic. Looking over he sees (Y/N) with multiple balls of light and fire magic around her. She then pointed her lance at him causing all of the light and fire magic balls to fly directly at him. Ult.All Might just smirks at this and began dodging or deflecting them. A growl escaped (Y/N)'s lips as she then pointed her shield at him firing a shield of the just towards him. Ult.All Might again just smirked at this and lifted his hand causing a gap to open up in front of him. The beam went inside the gap and another gap opened up behind (Y/N). (Y/N) quickly turned and was met with her own attack hitting her in the back kicking up a lot of smoke. Ult.All Might laughed at this as a green flash burst from where Ult.Brainstorm was along with burst of Holy energy from where (Y/N) was. The smoke around (Y/N) dispersed revealing her in her Dukemon form her holy aura surrounding her. A claw then emerged from the rubble where Ult.Brainstorm was with him then emerging completely from it though instead of him still being Ult.Brainstorm he was now transformed into his Appoplexian form Rath. Rath lets out a tiger's roar as he growled towards Ult.All Might.

Rath: LET ME TELL YOU SOMETHING YAGI WHO HAD ESCAPED FROM THE NULL VOID PRISON! RATH DOESN'T CARE HOW MUCH POWER YOU'VE STOLEN! RATH WILL BEAT YOU INTO A BLOODY PULP AND PUT YOU BACK BEHIND BARS WHER YOU BELONG!!!

With that the two rushed at Ult.All Might who just smirked at them. Rath went for a punch that Ult.All Might simply blocked, then throwing his own punch into Rath's gut stunning him before he was thrown away. Dukemon stabbed at him with her lance that he parried leaving her open for Ult.All Might to then fire a blast of magic into her gut sending her flying back. Rath roars out in rage before jumping at him going for a punch that Ult.All Might dodged. Rath growled in rage before attacking him again. Rath kept attacking while Ult.All Might continued to dodge his attacks. He went for another punch that was countered by another magic blast from Ult.All Might sending him flying back once again. He was sent into a wall with some chunks of it falling onto him. He then looks over seeing  Dukemon getting back up, he smirks at her causing her to growl in rage. She lifted her lance charging energy at the tip of it. She drew her lance back once the energy fully charged and launched her Lightning joust towards him. He smirked again and lifted his hand blocking the attack. He then closed his hand shattering the attack. Dukemon looked on in shock as Ult.All Might rushed towards her hitting with a strike to her gut before knocking her back. He held his hand up to her as multiple gaps opened up all around her shocking her. Seconds later multiple beams came out from them and hit Dukemon all around. They soon stopped as Dukemon fell to a knee, being injured from the blasts. Ult.All Might was about to approach and finish her off but was stalled when Rath jumped at him and began to grapple with the magically charge ex-hero. As they grappled Dukemon heard a voice in her head.

Grani: Are you alright? I feel your energy dropping

Dukemon: Yagi managed to steal the magic from the queen and sages. We're having trouble dealing with him

Grani: I see, I'm on my way to help then

Rath continued to struggle against Ult.All Might until he was pushed back and was hit with a magic charged punch to his face. Rath stumbled back a bit before growling and rushing back into to the fight. Dukemon continued to try and pick her as she then felt the digital biohazard begin to heat up, but it felt like power begin to flow through her as well. Outside with Grani they began to glow as well as they approached the castle. Grani fired out a blast towards the roof where they were blowing the roof open creating a hole. This caught everyone's attention, though this also left Ult.All Might open for Rath to hit him with a stomach punch. This distracting Ult.All Might once again as he continued to battle the Appoplexian. Once Dukemon lays her eyes onto Grani she felt the power grown along with the glowing getting brighter. Grani had felt this as well.

Dukemon: Grani, what's going on?

Grani: It seems that the Digital Biohazard had begun to start the fusion process between us

Dukemon: Fusion process?

Grani: Yes, it will be better for you to see for yourself. Now come let us begin

Dukemon nods and jumps towards Grani as they flew down towards her. Once they make contact with each other a sudden burst of light shot out around them catching the attention of Rath and Ult.All Might. The light then shot down to the ground and landed. It soon dissipated seconds later revealing Dukemon kneeling there, now in crimson red armor with six wings coming from her back now. Her lance had transformed into a dual side lance and her shield had transformed into a sword.

 Dukemon got up and looked at herself.

Dukemon: What's happened?

She then heard the voice of Grani in her head.

Grani: We are now merged together, we have now activated crimson mode!

Dukemon: Crimson mode? I guess that makes us Dukemon Crimson Mode now!

Ult.All Might knocked away Rath and approached her.

Ult.All Might: It doesn't matter what you are now, I'll still kill you

Dukemon CM glared towards him and got into a stance ready to fight.

Dukemon CM: We'll see about that bastard!!

The two then rushed towards each other. Ult.All Might threw a punch at her but was shocked to find her parrying his strike. She then swung her sword slashing him across the chest shocking and injuring him. He stumbled back a bit in shock before he was then hit with a kick to his chest. She quickly followed up with multiple slashes with her sword before sending him back with one last slash. Growling in anger before sending multiple magic blast at Dukemon CM, only for her to slash right through them with ease. She rushes towards him and delivered multiple kicks before ending it with one large slash. Ult.All Might held his side in pain as he continued to glare at her. She went for another slash that he quickly avoided by jumping back. He then held his hand up towards her again and opened up multiple gaps around her once again. Beams were about to fire out again, and as they did a being who looked to be made of rock and crystals jumped down in the middle and absorbed the beams as they fired out. This was DOTHOH (Y/N) in his Crystalsapien form Chromastone.

Ult.All Might looked on in shock as the beams stopped firing and the gaps closed. Chromastone reeled his hands back charging up energy between his hands. He then thrusted them forward firing out a large beam of energy at Ult.All Might. It makes contact with injuring him from having his own energy shot back at him. Ult.All Might looked on in anger as magic energy charged all around him, the machine on his arm beginning to glow brightly as well.

Ult.All Might: I won't lose to punks like you! Not when I have all this new power, NOT AGAIN!!!

He charged his energy up to the max and fired out a large beam towards the two. In response Dukemon CM drew back their new lance energy charging all around it. They then thrust it forward sending out a large beam of their own.

Dukemon CM: Final Justice!!

Chromastone helping out too adding more power to the beam, with it completely overtaking Ult.All Might's beam. The two's combined beam hit Ult.All Might directly causing a large explosion along with a large cloud of smoke upon impact. The smoke soon cleared revealing a heavily injured Ult.All Might. Dukemon CM takes notice of the device of his arm and quickly rushed towards him faster than he could react. Once she made it to him, she quickly sliced the device into pieces.

Ult.All Might: NNNNNOOOOO!!!!

 Once the device was destroyed all the magic bursts from it and went back to their rightful owners. Yasaka, the sages and Satori all awoken now that their magic had returned to them. Ult.All Might shrunk back down to his regular form. Yagi looks up seeing Dukemon CM, Chromastone, Yasaka, Yukari, Okina and Satori all glaring down at him. We then cut to a bit of time later seeing the White Fang Members being put into custody of by the Youkai Kingdom and Lunar Rabbits. We also see Yagi in energy restraint cuffs. DOTHOH (Y/N) stood in front of a portal leading back to the Null Void prison, hold Yagi by the arm so he couldn't get away.

DOTHOH (Y/N): Well, talk about a relief. Thanks for helping me get this guy back into custody

(Y/N): No problem, just make sure he doesn't get out again

DOTHOH (Y/N): Don't worry, we got a "special" place for him this time

When he said "special" Yagi growls at him a bit.

DOTHOH (Y/N): Well, either way thanks for the help. Maybe we can meet again, hopefully under better circumstances

(Y/N): That'd be nice, and once we do meet again you'll be owning an apology to all my precious rabbits

DOTHOH (Y/N): R-Right, away I should be off. See ya

He gives them a two-finger salute and stepped into the portal dragging Yagi along with him. The portal closes shortly afterwards. After that (Y/N) lets out a small sigh and turns to the main figures of the Youkai Kingdom.

Yasaka: Thank you for your help in protecting our kingdom (Y/N)

(Y/N): It's no problem we are allies after all

Yasaka: Either way I say this is cause for a celebration. Let us have a feast

They all cheer as the camera fades to black. The camera soon comes back in showing a floating mass of land in a red void like area.

This was the Null Void prison. Going inside we see multiple prisoners going around while being watched by the security. Going further inside we head to the solitary confinement cells, with one being kept far away from others. Inside was Yagi who was basically chained to all the walls, while he also had power nullifying cuffs attached to his wrist at all times now. He sat in his cell mulling over his lost wanting nothing but to break out and kill (Y/N) Tennyson, Midoriya and the last person who had one for all who made a mockery of him.

???: Well, isn't this a pathetic display

Hearing that voice Yagi looks up seeing the one who helped him escape in the first place. A large skeleton like figure.

Yagi: You, get me out of here. I still need to get my revenge on Tennyson and Izuku!

The Skeleton Figure got into a position like he was thinking mockingly. Before he just chuckled to himself.

Skeleton Figure: Sorry to say but no. You've served your purpose

Yagi: What?!

Skeleton Figure: You've proven the suspicion that I had about that world. And now I have no longer use of you. Though I will take the power of that soul of yours

He lifted his hand as a floating skeletal hand with a spike appeared. Before Yagi could say anything else the hand launched into his chest and began to drain his soul. A dark yellow heart was shown as it was quickly drained causing the skeleton figure to laugh.

Skeleton Figure: How ironic, a soul of justice transforming into a soul of corruption, it's almost poetic

Once Yagi's soul was drained his body fell over limp, he was no longer breathing either. The Skeleton Figure began to morph and grow after he did this.

Skeleton Figure: Now, (Y/N) Guilly. You are the one I've been searching for. You hold one of her pieces. Heh heh heh heh
