Heroes for the greater good

This is a BNHA Warhammer 40k crossover.

This story was actually voted on ages ago when I was still writing Death Korps Hero but I kind of forgot about it when GW pulled their usual BS around fan works. So to those who had looked forwards to this I apologise for the delay. For those who were reading Darkest Hero it will continue on.

Please note that Tzeetch will be a bit confusing to read and that is on purpose. One second they are a female entity with a cat head and human hands, the next they are a male octopus with feathers and a pair of feet instead of eyes, that is just the nature of the god and I apologise in advance for how headache inducing it will be to read, I hate writing like that so I'll endevor to write the god of change as little as possible in the story.

Yes this is a story about demonic entities screwing with reality if it offends your religious beliefs then please read something else instead of sending dozens of PMs with text from religious texts decrying me as a sinner who deserves to rot in a lake of fire which I received while writing Darkest Hero. Not only is this annoying it borders on harassment at times furthermore why the heck do you do this every time I post? it is childish, just unfollow my account if you are that offended. To those who are able to handle it without going hyper religious, thankyou.

To avoid any complaints here is the current warning list. Contains: romance, swearing, body horror, lemons, violence, death, demons, daemons, daemonic gods, supernatural themes and gore.

Chapter 1: Godly intervention.

Magnus was old, that was a fact. Even though he had survived the curse that turned his sons to ashes he himself was now too turning to ash within his armor, it was not the work of any curse, weapon or virus but simply time. Looking back on his long life he could only lament on all his mistakes, probably the worst being how he tried to warn his father about Horus. But such things mattered not anymore. Here he was, kneeling knees deep in the blood and gore of the world eaters who had at one point held command over the ship the Conquerer. Before him, twisted and fused to the pilot's chair by daemonic tendrils and fractured metal was a black haired human woman, a bloodied hand print was visible on the tattered remains of her uniform amists several pipes that fed into her chest and abdomen. Next to her laid the headless body of what was once Khârne the betrayer, the finest mortal champion of the blood god. With a weary breath he brought his hand to the head of the drooling corpse of a woman before crushing their skull to a meaty pulp with a wet squelch and crunch.

"There. My task is done." Magnus panted as he fell to his side, his legs now nothing but ash as his hands started to crumble. "As you promised Tzeetch you must help humanity." With a final breath the primarch was no more than a pile of ash slowly soaking up the blood that it sat in.

Within the warp Tzeetch blinked all ten dozen of her eyes owlishly before he huffed in annoyance. Old gnarled hands reached out through the warp looking for a suitable target to help humanity as little as possible while still fulfilling the bare minimum of the deal. His feathered hands eventually settled on a Tau craft stranded amists a warp storm currently dealing with some of her pink horrors. It was a simple matter for her to snatch up one of each cast through the lack of Gellar field on the craft as her tentacles grabbed a cosmically large glass jar to store each in as his single eye blinked at the five Tau trying to break free, none able to perceive them asides the ethereal who was shaking with fear, her eyes trained directly on the quivering tau who stared back in horror.

"Hmm, these will do." It hummed as the ethereal fainted. His hands clasped the bottle and shoot vigorously liquifying the tau inside. "Now, harvest the knowledge from these ones and send it to a human to help humanity." The now dog headed being hummed as its crab claw let go of the container. "Ill send it to a side reality! Keeps the contract valid. Poor magnus didn't know what he was betting the fool."

With a burst of multicolour techno vomit that was the warp a small blue orb formed from the slush inside the giant jar, no bigger than a pinky toe bone. "Lets send this somewhere else." They cackled as the god of change flicked the small orb through a purple and negative rift and into another world.

[Side reality B79244-C.]

An athletic and rather tall green haired woman hummed happily to herself as she set about making breakfast for herself and her son Izuku, her husband had already left for work for the next few months the night before. The man worked overseas making business deals with various other companies contracted to the one he worked for but he always made sure to come home when possible to spend tim with his family and to send money back home to support them. With a satisfied smile she floated the knife over to the sink using her quirk as she walked the two plates of omirice to the table and sat them next to a cup of juice either side of the small round table.

"Izuku, breakfast!" Inko called as she used her quirk to pull cutlery from the drawers to the table where they neatly arranged themselves. A loud yelp and thud filled the apartment followed shortly by a scream of shock and excitement. The green haired woman rushed down the hall towards her son's bedroom, the first aid box flying behind her with a green glow.

"Izuku!" She gasped as she ripped open the door. Her son had managed to wrap himself in the blankets and had fallen out of the bed again. With a soft sigh the medical box placed itself neatly on her son's desk as she knelt down to help untangle her son. Within seconds her son's messy mop of green hair was once more free of the blankets.

"Mum! I got my quirk!" Izuku shouted with joy as he pulled the blanket away from his face and legs almost making Inko faint with joy and shock, thankfully the woman merely froze in place. "I got horse feet!"

Overnight her son had gone from an ordinary green haired four year old boy to having hooves and slightly larger than normal eyes with no nose.

"Oh my goodness!" Inko gushed excitedly as she picked up her son, spinning him around while hugging him tight. "My little baby finally got his quirk! We have to call your father!"

"Yay!" Izuku cheered as inko sat him down only for the small boy to loose his balance and fall over. "I think my horse feet are wonky."

"Hooves izuku, they're hooves. Come on, I'll help you get up." Inko chuckled softly as she helped her son back up. With wobbly knees the two made their way to the main dining area where Izuku pulled himself into a chair infront of the omnirice. "Eat up sweetie then we'll call your dad."

"Ok mum." Izuku nodded as he dug into his food while Inko turned towards the phone. He swallowed his third mouthfull only to stop abruptly and gag.

"Izuku?" Inko asked in worry before yelping as her son threw up across the table infront of him. Panicking she rushed back to the table to try and help her son.

"It hurts." The green haired boy groaned in pain as he clutched his stomach.

"Its okay sweetie, mummy will get you a doctor." Inko hushed izuku as a roll of paper towels flew over with a green glow and began to mop up the mess while she pulled the phone off the reciever and dialed the nearest doctor's office.

With another groan izuku stumbled out of the chair and tripped over, barely catching the side of the bin before once more he vomited, thankfully this time the mess was contained to the garbage bag within the bin.

"Hold on sweetie, I'm getting them now." Inko tried to console her son as she glared at the omnirice, thinking it was probably a bad ingredient in the food that caused this to her son.

[Elsewhere]

Hisashi Midoriya sighed as he stuffed the picture of his wife and son back into the pocket of his black jeans and donned a heavy respirator that covered his throat and lower face allowing only his eyes to be seen. The warehouse he was in was dimly lit but several vats with a amber liquid were spaced around, each containing a hideously mutated being. Standing to the side of a computer hooked up to the vats by thick cables was a hunched grey haired doctor with thick bottle cap goggles and a mist like man in a butler's uniform, a silver collar around their neck.

The sound of a Nokia ringtone echoed through the warehouse as Hisashi glared at the doctor who was fumbling with his phone.

"Hello Doctor Daruma speaking." The doctor started before his face grew progressively paler as the conversation went on. "Of corse, I'll be over right away. I'll see you soon."

"Who was it?" Hisashi asked, his voice distorted by the mask.

"Your wife sir." The doctor gulped. "Your son has food poisoning."

"Damnit." Hiashi growled in annoyance as he clenched his fist. "I can't even be there for my family without raising suspicion and putting them at risk. Leave now and make sure my son gets better or so help me Daruma I will strip you of your quirk!"

"O-of course sir!" The doctor stuttered before bowing and rushing off for the door.

"Sir, should we put this off?" The mist man asked curiously.

"No, send me to him, I want to wipe the blonde bastard off this planet so I can raise my family in peace." Hisashi barked back. "Him and his fucking predecessors have always been major pains in the ass but the blonde idiot really fucking takes the cake."

The mist man bowed politely as a misty vortex portal opened up infront of Hisashi. "Of corse All for one."

End.
