In the forest camp...

The members of the Vanguard were waiting for Dabi's fire signal to start their attack om the unsuspecting heroes.

Dabi and Twice were in the middle of the forest waiting for their own signal to start. Suddenly a prescense alerted them both from behind. They turned to see a pair of purple eyes staring at them.

William: Its time, come on you weak-asses.

William walked passed them and stared at the camp. Dabi growled and used his quirk to set the woods on fire.

William: Now then....

William walked further into the forest while Dabi and Twice stared at his back.

Dabi: I cant beleive I have to follow Mr. Grape fucker's orders.

Twice: I feel bad for whoever encounters him../ No i dont!

Dabi: At least we are not with that brocoli pimp, we only met him for like 5 minutes and I hated every single second of it.

Flashback.

The Vanguard was in the room of the LoV's hideout when suddenly a portal opened, and Izuku stepped out of it.

Izuku: Hey Handy! I am back.

Shigaraki: Stop calling me that you rotten bush.

Izuku: Hey hey hey! No need to be rude!

Shigaraki: Whatever, this is the group who I told you about, did you get your comrade to join?

Izuku: Yes I did! And oh so this are the ones!

Izuku looked at the group and approached them.

Izuku: So who are you?!

Dabi: The name is Dabi, and step back dont you know personal space?

Izuku: Mmmm, No I dont!

Izuku stepped closer to Dabi who in turn used his quirk on him, Izuku began to laugh as he was on fire.

Izuku: Ooohhhh you are making me hot!

Dabi: The hell?

Izuku: Thats my home!

Suddenly the flames disappeared and Izuku acted as if nothing had happened.

Izuku: You are?

Mr. Compress: I am Mr. Compress! Do you want to see a magic trick?

Izuku: Blow my mind!

Mr. Compress raised his hands to show two marbles in his hands, he turned his hand and wiggled his fingers and suddenly they were gone.

Izuku: Hahahahaha! That sure was a fast hand trick! I wonder what else you can do with those hands! Say! I also know a magic trick! Let me shuffle the functions of every hole in your body!

Izuku snapped his fingers and suddenly Mr. Compress' mask fell to the ground and everyone could see what Izuku had done.

Izuku: Hahahahahahahahaha!

Shigaraki: Midoriya stop it now!

Izuku: Ugh! You are no fun.

Izuku snapped his fingers again and Mr.Compress returned to normal.

Izuku kept watching.

Izuku: And who are you?!

Toga: I am Toga! I like blood!

Izuku: Hello you are totally not a yandere copy!

Muscular: I am Muscular.

Izuku eyed him for a while.

Izuku: Someone is overcompensating.

Moonfish: I... Want fleeeeshh!

Twice: I am Twice, a pleasure to meet you!/ No it isnt.

Izuku: You are weird! Hahahahaha, I like you!

Mustard: I am Mustard.

Izuku suddenly stared at him deadpanned.

Izuku: Seriously? Mustard? I see you are lacking a bit on the brain department.

Magne: I am Magne.

Izuku: Oh and what can you do my feminine fellow?

Magne: Well... I can suck your D.

Izuku: Ha! No!

Izuku stepped aside from them to look to the last person on the room.

Izuku: And who could you be?

Spinner: Dont talk to me as if we were pals! You killed Stain! Shigaraki! You didnt tell me this guy was with you!

Spinner took out his katana and pointed it at Izuku's face who just watched him with a smile on his face.

Spinner: I am going to kill you! You are going to suffer the most horrible way to die possible! Stain was a saviour and you murdered him! Its only fitting for your death to be start of the new hero killer who will cleanse this society!

Izuku: Wow that is a lot coming from an overgrown lizard.

Spinner: You are dead!

Spinner slashed his sword at his neck but Izuku instantly regenerated the damage.

Spinner: What the-

Izuku: Mate if it was that easy to kill me...

Izuku suddenly appeared in front of Spinner and stabbed his hand through his chest and ripped out his heart, just like he did with Stain. Spinner dropped to the ground and Izuki dropped the heart.

Izuku: Anybody in for some Iguana burritos?

Everybody looked digusted at Izuku, except for Moonfish.

Moonfish: Me!

Shigaraki: Stop this nonsense they have to get prepared. That ally of your better be worth the man you just killed.

Izuku: They? What about you?

Shigaraki: I am injured remember?

Izuku: Oh yeah I guess you could better say you are handicapped.

Shigaraki: Ugh go away!

Flashback ends.

Dabi: I swear if he had stayed for just one minute more I would have burned myself to a crisp. Lets go Twice you know what must be done.

In the forest William kept walking like a predator searching for his prey. He then saw at the distance a group of 5 1B students. They looked scared, just like he liked them to be. In almost the blink of an eye he reached were the students were. The students feeling a presence behind them turned to see William.

William: Hey kids!

The kids stared in shock at William who moved in the blink of an eye and used his axe to chop their heads off, their horrified expressions still marked on their faces.

William: That was way to easy! I like it when they fight back, it makes it more excitng Hahahahaha!

???: What the....

William turned his head back to see a girl with orange hair and green eyes along with a boy with grey hair and eyes standing behind him.

William: Oh? More guests have artived!

William turned completely to face them and smile widely at them. He moved fastly to attack the two students.

Tetsutetsu: Kendo watch out!

Tetsutetsu activated his quirk throughout his whole body and stepped infront of Kendo to protect her. William's axe smacked his kneck and managed to cut through a little. William widened his eyes. Suddenly Tetsutetsu used his quirk and snapped William's axe in two. William stepped back and stared at them.

Kendo: Tetsutetsu! Are you okay?

Tetsutetsu: Y-yeah this is nothing.

He then pulled the axe out of his neck but somd blood also came out.

William: Impressive! Finally someone who fights back! Lets see for how long you two can hold out! Hahahahaha!

Suddenly a kinfe appeared on his hand, as he watched the teenagers tremble he began to laugh.

Meanwhile in another part of the camp the hero students were fighting back the villains. Magne and Muscular were a formidable duel. They managed to kill Pixie Bob in an instant meanwhile Uraraka and Tsuyu were fighting Toga back and Mustard was fighting against Momo. Moonfish was trying to eat Mezo and Tokoyami meanwhile Aizawa was able to locate Dabi and Twice and was fighting them back. Angela and Todoroki joined the fight against Muscular and Magne, and they were able to change the tide of the battle with the abilities the hell flame gave them. Suddenly Angela, Todoroki and Aizawa felt a chill go down their spine.

Angela: What the....

Todoroki: You felt it too?

Angela: Yeah...

Todoroki: Something bad is in there.... Its like the hell flames are telling us that...

Angela: We are the only ones who can fight a demon so we must go.

Todoroki: Yeah.

Aizawa: 'What is this.... A bad prescense is inside the forest.... Something really bad... I will tie this guys up and go check that out'

Meanwhile in the suicide forest.

???: Its been a while since we had visitors right Ender?

Abaddon: That voice... Nightmare?

Nightmare: Hello Abaddon how long has it been.

Abaddon: Dont tell me you joined that bastard!

Nightmare: Its just bussiness, why would I remain on the losing side?

Albert: This guy is Nightmare? That really ancient and powerful entity?

Abaddon: Yeah.

Albert: Are you one of this Lords of Hell?

Nightmare: Me? Oh no, I am an advisor to the lord.

Abaddon: I am not sure if that is a higher or lower rank.

Albert: One way to find out.

Albert's arms were suddenly engulfed in blue hell flames.

Abaddon: Right.

Abaddon took a fighting stance.

Nightmare: I have never met someone so eager to die.

Suddenly Ender attacked Abaddon and kicked him away from the battlefield. Meanwhile all the shadows attacked Albert who had to create an energy shield to protect himself. Albert jumped and as he did, he ignited the ground with fire, the shadows retracted but then launched themselves at Albert, who summoned his hell flame sword and began to cut through the shadows. Albert ran towards Nightmare and was about to stab him when suddenly a second mouth appeared on Nightmare's belly, black fire came out of it and Albert jumped away from Nigtmate to avoid it, then more shadows emerged from the mouth. Albert created another shield but this times all the shadows pierced through the same spot at once, Albert was surprised and jumped away to avoid being pierced himself, but the shadows followed him, Albert summoned a fire ball and threw it at the shadows, they dispersed but then they engulfed Albert in a dome of shadows. Suddenly a bright light started to emerge from the inside, piercing through the shadows and then dissolving them. Albert then came out of there.

Albert: Thisnis going to be a lot harder then I thought.

Meanwhile with Abaddon.

Ender landed on top of Abaddon who used his arm blade to try and cut Ender who just teleported away. Abaddon stood up and looked around but couldnt see Ender. Suddenly Ender appeared from behind and smashed him in the head into ground. Abaddon quickly rolled and turned to shoot Ender with a blast but when he did, Ender teleported away, again. Abaddon stood up, wary of his surroundings.

Abaddon: This will be difficult....

Back at the camp, Todoroki and Angela were running through the forest. They felt the evil prescence was closer and closer with every step they gave.

With William.

William stood over the bloody corpse of Tetsutetsu. He had also killed a blonde hair boy with black stripes and a gnome with purple hair and balls on it who were unlucky enough to stumble with him. Meanwhile on the floor lied a bloody yet still alive Kendo. William turned to look at her.

William: I was really hoping you would last longer but oh well... Time to end this!

He walked closer to her an axe suddenly appeared on his hand, he raised it and brought it down, he was about to hit her when suddenly a barriage of blue flames engulfed his axe and part of his arms. William widened his eyes and stumbled backwards, letting the burnt axe fell to the floor.

Todoroki: That was close.

Angela: Kendo!

Angela quickly jumped to Kendo's side, grabbed her and jumped back to Todorki, he laid her on the ground.

Todoroki: So, you must be the demon.

William: Oh? Pure hell flame? How interesting.

Angela: You will pay for what you have done!

Suddenly Angela clenched her fists and a small trace of blue flames appeared on it.

William: You too? This is something else! But you see, you will need more than that to beat me!

William raised his arms to show them they were unaffected.

Todoroki: H-how?!

William: Those flames only work on demons' bodies.

Angela: You are not a demon?!

William: Oh I am a demon!

He showed them the back of his hands to reveal the number 6 on each one of them.

Todoroki: You are one of the Lords of Hell!

William: Damn right I am!

Meanwhile from where she was Kendo was hearing everything, her mind tried to comprehend what was going on.

Kendo: 'Hell flames? Demons? Lords of Hell? What is going on?'

Todoroki: Then why are you unaffected by it?!

William: As I told you those only work on Demons' bodies. This is a human body.

Angela: What?!

Todoroki: You possesed someone?

William: No, this is my body! Let me explain, all demons that follow Izuku used to be humans, evil humans who died and went to hell, including the lords, they followed the new lord and in exchange he gave them power and demon bodies. I was a different case. I used to be a security guard on a kids restaurant in th 1980s, I used my positions to kill kids while diguised as one of the mascots to prevent being discovered. I murdered them to harvest their souls, I was sure I could use them to become immortal! But it all went wrong, the souls escaped and trapped me, I used my old disguise to hide from them, but the disguise had a malfunction and it activated the robot mode as it was one of those old springlocks suits, it killed me, horribly, well at least it should have, but I was cursed, I got what I wanted, immortality, but I would have to spend the rest of eternity inside that suit suffering the pain that should have killed me for over 200 years. Then the lord found me, and offered me a second chance as his server he gave me an enchanted material that freed me from my curse and now I am here.

Todoroki, Angela and even Kendo had disgusted looks on their faces as they processed what this man had done.

William: And that is the end of the tale.

William summoned two knives and grabbed them.

William: You die here kids!

Todoroki: As if!

Todoroki used his normal fire against William who jumped away he then landed to be greeted by a huge ice barriage. He used his knives to be able to cut through them. He then jumped high and summoned a bunch of knives around him which later threw themselves towards Todoroki. Todoroki managed to jump away then Angela dodged the other incoming knives and using the boost she had she jumped and managed to punch William back into the floor. Angela landed back as well but had to quickly dodge the incoming knife attacks from William. She barely managed to dodge even getting a cut in one of his cheeks. She jumped back and flicked her finger sending a wind wave against William. William jumped and then saw the incoming fire attack from Todoroki, William spun mid air and dodged the attack. William landed back and ran towards Todoroki, who then used his ice to generate ice spikes. William couldnt stomp in time completely and one of his arms was pierced. William jumped back and regenerated his arm, but as he was distracted, Angela came and kicked him in the back, sending him flying straight into new ice spikes Todoroki had generated, impaling him in several places. William managed to get off the spikes and regenerated.

Wiliam: Thats it...

William the dropped his knives and charged against Angela, hebgrabbed her from the leg and raised her then slammed her back into the ground, making a crater. He then in the blink of an eye appeared near Todoroki and slammed Angela against him sending them both to the ground. William then summoned an axe and looked down at them.

William:

William was then suddenly kicked in the face and sent back.

Aizawa: Stay away from my students!

With Abaddon

Abaddon kept trying and failing to hit Ender, his teleportation was really starting to get on his nerves while he was also getting tired of getting hit.

Abaddon: 'There must be a way to kill this guy'

Abaddon turned to look at Ender and looked at the pearl in the center of his chest.

Abaddon: Hm, that looks important! Well time to show you why I used to be one of the regents of hell!

Abaddon suddenly started to bulk up while red veins appeared through his body.

Abaddon: You will regret fighting me!
