There was so much tension in the air that everybody could almost taste it, the Special Training session was about to reach it's climax

You found yourself face to face with the Fusion between Midoriya and Bakugo, Katsuku. You sensed a drastic increase in power within him

Y/N: And who are you supposed to be?!

Katsuku: Me, I don't really have a name yet, but with all things considered, I'll call myself Katsuku: The United Hero!

Y/N: Hm...You're definitely stronger, there's no doubt about that...let's see how you handle Super Saiyan Blue!

With your godly speed you dashed towards Katsuku at full speed, balling your hand into a fist as you gritted your teeth with a grin

The sound of your fist smashing into something could be heard as everybody looked away or flinched, which was why they were surprised to see that he had vanished

Your fist was pretty much stuck in the ground as Katsuku had completely vanished, even catching you by surprise

Y/N: He's fast...I can't tell how powerful this fusion really is since a new method was used...but his energy did skyrocket, he's probably on par with Goku Black the way he is right now...

Slowly looking up into the sky, Katsuku could be seen in the air above you, with bits of orange and green electricity surging through his body

Katsuku: ONE FOR ALL: FULL COWLING: 75%!

Katsuku then caught you off guard with his speed as he appeared directly in front of you in the blink of an eye, clenching a fist as he reeled his arm back

Katsuku: DETROIT SMASH!!!

You then received a powerful punch to your stomach area as his fist dug into your midriff, as he twisted his fist it started to hurt even more as you were then launched backwards

Bits of Orange and Green electricity surging into your torso as you raised a brow in confusion, before you could recover a large chain of explosions occurred directly on you

Uraraka: Talk about Strong!!

Iida: Not only are their powers combined, but so are their quirks!

Ruby: We might have a chance after all! Issei, Keep boosting your energy, we'll hold him off for as long as we can!

Issei: Gotcha!

Rias: You heard her! Let's do this everyone!

As Katsuku gazed upon the large cloud of smoke from his explosion attack, he smirked and looked at your direction with a sense of cockiness

Katsuku: Is that all you got? I was hoping for more! C'mon!

In a sudden flash of yellow light your energy bursted from the cloud of energy, you had changed, you your hair had grew longer and was rocking a certain shade of grey, along with your eyes turning bright red as you emerged from the left over flames from Katsuku's attack

Y/N: Not even close! C'mon show me more of that power of yours!

Katsuku: As you wish!!

With that the both of you rushed each other at high speeds, Katsuku amping his full cowing to 100% as you both clashed fists, resulting in plenty of debris to fly

Katsuku was sent flying from the impact as you rushed after him in a flash of yellow light, with him slowly looking towards you as he flew through the air

Katsuku: That form wasn't that strong when Deku last fought against it...what's going on here...?!

Y/N: That's what you fail to understand about the Primal Path of Saiyan Forms!

You then slipped below him and whacked him upwards with a fierce spin kick, shockwaves flying through the air on impact

Y/N: Super Saiyan 4 evolves and mutates when pushed to the limits, just like how it mutated to create Super Saiyan 5, my Primal power evolves to even greater heights every time I use it!

Katsuku: No way!!

Y/N: Yes Way!!

Katsuku: Then I gotta go all out! KAIOKEN x20!!!

You watched as the fused Hero then gained a large and powerful red aura that produced wind pressure capable of stopping you in your tracks, with you still smirking as your red eyes glistened

Y/N: HA!

Katsuku: HA!

Everybody watched in awe as you and Katsuku started to trade blows with one another, with Bakugo being part of the fusion explosions were going off everywhere

Uraraka: Wow!! Look at them go!!

Rias: Such power! I never thought that in any way a non-Saiyan student would push Y/N this far, Fusion or not!

Todoroki: They've both come a long way.

Amanda: I wish I could fight like that...

Meanwhile: Katsuku's Subconscious

Midoriya: I-I CAN'T BELEVE WE'RE KEEPING UP WITH Y/N!!

As it looked, Midoriya and Bakugo were able to watch the battle between their fused self and you from Katsuku's subconscious

Midoriya was crying up a literal storm as Bakugo sighed in annoyance to his gesture

Bakugo: Stop your crying, it's annoying...

Midoriya: O-Oh...*Sniff*...Right! We've got a battle to win!

Bakugo: Yeah...

Bakugo looked upon the fight from Katsuku's first person perspective, seeing that he was landing as many blows on you as you were on him

Bakugo: Now, Let's kick his ass, Deku!!

For the first time in his life, Bakugo looked at Deku with a smile in his face, not as a way of making fun, but was a way of strengthening a bond hanging by a threat that has been there since the very beginning

Reaching out to him, Deku could only stare in shock before wiping his tears and smiling as well, taking his Rival's hand

Midoriya: Yeah!!

Back On The Outside

You and Katsuku kept exchanging blows at a rapid rate as the land around you began to break and crumble before you

Everyone forcing themselves to gain proper ground as Akko gained a look of determination on her face

Sucy: What's on your mind now...

Akko: That Fusion isn't gonna last forever! It could wear off at any moment! We gotta help them in anyway we can!

Eye-Catch

Eye-Catch

Lotte: But how...? They're moving too fast for us to keep up.

Todoroki: I'll try to use my ice to keep him in place for as long as I can.

The trio of witches looked over to Todoroki in surprise seeing as he was willing to lend a helping hand, with Akko giving him a smile

Amanda: We'll help too! You three can't go in alone!

Diana and Jasminka nodded in agreement as Hannah and Barbara remained silent, Todoroki preparing his biggest and strongest ice attack as all of the remaining witches rushed towards the battlefield

Ruby and the others were doing their best to keep Issei on his feet, with every piece of land in the area bing destroyed by the battle, it was quite difficult to do so

Ruby: So what are you planning once you're done charging up...?

Issei: I'm gonna transfer this boosted power into Midoriya and Bakugo, then they can hit Y/N with one final strike!

Ruby: Oooh!

Meanwhile, You and Katsuku were still going at it as the fused hero suddenly aimed his palm towards you with a smile on his face

Katsuku: DELEWARE AP SHOT: AUTO CANNON!!

Y/N: STARLIGHT BOMBER!!

Quickly smiling after Katsuku, both of your attacks which both consisted of multiple projectile attacks began to collide into one another

Katsuku: Just how long do you plan on keeping this up, Huh?!

Y/N: Until I strike you down!!

All of a sudden a large bit of ice started to form under your feet, catching both you and Katsuku by surprise as the ice enveloped over half of your body

Y/N: What the hell?! Ice?!

In the distance, Todoroki could be seen with his hand in the ground, along with a large path of covering the distance between you and him

Todoroki: We don't have to beat him...just outlast him, it's almost nightfall!

Y/N: You think some ice is gonna hold me down?!

Todoroki: NOW!

As you broke your way through the ice, 8 ropes of magic energy, all different colours all wrapped around your body and held you in place, you went wide eyed at this as Katsuku gave everyone a thumbs up

Katsuku: Thanks for the help!!

You struggled to break free from the many ropes holding you down as they quickly began to drain the energy out of your body, strengthening rope, making you weaker and the witches stronger at the same time

Y/N: D-Dammit...!!

Issei: Yo, Fusion Guy!

Katsuku then turned around to see Issei running towards him, eventually reaching him and placing his hand upon his back

Issei: Take this!

TRANSFER

Katsuku then felt a massive increase in both energy and power, his muscles autonomously flexing and swelling similar to All Might as he smiled

Katsuku: So much power! Thanks a bunch!!

Issei: No Problem! Finish the job!

As the witches rope continued to sap you of your energy, you slowly reverted to Super Saiyan 4 against your will, gritting your teeth as you struggled greatly to break free

Y/N: Get...Off!!

Amanda: No way! This one's for Constanze!!

Katsuku: Let's do this...

Upon receiving Issei's Boosted power, Katsuku activated Kaioken x20, One for All 1,000,000%, Deku's God Ki, and the Boosted Dragon Power all at the same time, leaving everyone with a terrifying result

Just by standing there the fused hero was now quaking the entire continent as he readied one final attack to finish this fight

You watched with wide eyes as you reverted back to Super Saiyan 3 against your will, making it even easier for the witches to hold you down

Y/N: DAMMIT NO!!

Katsuku: HOWITZER...DETROIT...

Y/N: C'mon!! Get loose!!

Katsuku then suddenly appeared right in front of you with all of his power channeled into his one fist, this was it, the end of the battle

Katsuku: SMAAAAAAAAAAAAASH!!!!!!!

Upon letting out their loudest battle cry, the powerful fusion smashed his fist into your torso as bits of lighting of different colours began to surge onto your body, doing massive amounts of damage as you even coughed up blood

Y/N: I...WON'T LOSE TO YOU!!!!

All of a sudden as a last ditch effort you simply started pouring out energy, similar to Vegeta's Final Explosion, however this version being a lot more powerful

Y/N: HAAAAAAAAAAAAAAA!!!!!!

Almost instantly breaking free from the Witches' ropes, everyone in the surrounding area was instantly blown away by your energy, including Katsuku who was doing his best to hold it off

Katsuku: Damn!! You're not getting rid of me THAT easily!!!

However, with time not being on his side, Katsuku suddenly glowed white for a short moment before splitting back into Midoriya and Bakugo

Midoriya: O-OUT OF TIME...?!?!

Bakugo: DAMMIT!!!!!

With that everybody was engulfed in the massive dome of energy that continued to spread across the entire training field

Meanwhile, Kalasha, Aizawa, Whis, Sirzechs, and Kasai all watched from the distance as a massive explosion engulfed the entire training grounds

Kalasha: Looks like they even managed to pin Y/N down.

Aizawa: In all honesty I underestimated those witches, I guess they have their use after all.

As the explosion finally started to disperse, smoke covered the entire landscape as everybody was lying on the ground as a result, however, a few students managed to survive the explosion unharmed via rubble

Asia: W-What happened...?

In the distance you could be seen on your knees, all around you with the witches, Midoriya and Bakugo, Issei, Ruby, and Todoroki, all unconscious as you panted heavily while facing down at the ground, there wasn't even a shine in your eyes anymore

You couldn't form any words, nor could you exactly move properly, all you could do was pant for air as the remaining students slowly began to surround you

You had lost
