Killkrumpa charges through the Warp portal, roaring his war cry. He barely notices the insane screaming of the Warp gits that surround him for the split second he passes through their realm. His mind is completely focused on the bug-eyed gits he is about to krump. He passes from the lab on the AI's ship and into their nest hundreds of miles away on the other side of the massive space hulk in a second, crunching the heads of several sleeping bug eyes under the massive tread of his new steel boots, or are they his feet since he…ahhh fuck it. He opens fire with his shoulder-mounted Warp shootas, sending green dakka flying everywhere. The four-armed bug eyes, who he knows are called Genestealers, are caught completely by surprise as each of the Warp rounds hit with small explosions that tear into three or four at a time, blasting them to pieces, some of which are thrown into the Warp itself. Killkrumpa barely even notices the silver war mask with glowing red eyes that forms over his face, augmenting his vision.
"Wakey, wakey, ya gits," roars Killkrumpa, a roar intensified coming out of the speakers of his war mask, "My name is Killkrumpa Weirdblitz, and I have come back for round two! I'm here to krump ya all!"
He continues to fire as the bug eyes finally get their act together. Not that he cares but he is outnumbered about a thousand to one. They start to swarm him, and Killkrumpa laughs as he wades into them with his crackling arm choppas. Despite his size, he is faster than he ever was before. The blades carve through them like they aren't there and like the dakka sends pieces of them into the Warp. His shootas keep firing on their own. He barely notices this as the female Ork AI takes control of them as smoothly as blinking. He is a Warp-fueled Orkie whirlwind of slaughter, and he is just getting started.
"Hey, Red," yells Killkrumpa as he cuts four bug eyes in half at once, "Why do they have four arms, and I only have two? And these shoulder shootas are the business, but can't I have some for my hands?"
"Red," says the AI in his head with a sigh, "I suppose I do need a new name for this new life of mine. You are such a child, but that does give me a chance to test these out."
Nanobots swarm out of a port in Killkrumpa's back, where they are stored by their billions. He has several of these ports all over his new body. They moved into place to form two more arms below his current ones. I'm the hands of these two new limbs are two guns, each the size of two large, grown human men put together. When he fires them, the roars are like an explosion. They fire rounds the size of a human torso. When these rounds hit, they explode in a wide cone of green Warp fire in a cone that continues ahead for a dozen feet.
"Now this is more like it," roars Killkrumpa, as the pure destruction he is unleashing sets his Ork soul ablaze, "That's right, step up so I can knock you down, ya gits! Tell em who sent you! TELL THEM YOU GOT KRUMPED BY KILLKRUMPA WEIRDBLITZ, THE WEIRDBOSS!"
He walks through their claws and fangs like one Ork. WAAAGH comes knocking. With Red on in his head and watching his back, he slaughters everything moving in the chamber and goes looking for more. She opens portal after portal for him to storm through into chamber after chamber, each filled with more and bigger bug eyes to krump. He smashes Warriors, crushes Hormagaunts, eviscerates Carnifexs, and fries so many more. With each kill, his power and bloodlust grow stronger. He is so strong by the time he reaches the Hive Tyrant he simply tires it and everything guarding it to ash and mush without even slowing. The psychic shockwave sent out by this massacre to every surviving Tyranid on the space hulk either kills them instantly or sends them cowering. None of them want any part of what the Weirdboss is serving.
When there is nothing left living in before him, Killkrumpa finds himself calming down until he is calmer than he could every remember being. As this happens, the massive amount of Warp energy he had gathered during his rampage washes from him in waves. Without even realizing what is happening, the Weirdboss changes the chambers of the Hive Tyrants chambers into something more to his liking. He falls onto a throne made of steel and bone big enough to fit him that wasn't there moments before, and the war mask retracts allowing the smell of death and destruction to fill his senses. He reaches down and tears an arm off a dead bug eye and lazily begins to eat it as he sits…thinking. This is new but not unpleasant. It gets more pleasant when a smiling Red appears, sitting on one of his massive legs.
"Well, that was actually quite fun," says Red, looking around at the destruction, "I won't lie, experiencing battle from an Ork's perspective is more enjoyable, even addictive."
"There is nothing more fun than fighting," says Killkrumpa as he finishes his snack, "Fighting is living, and living is fighting. I will say it is less fun without Boyz to enjoy it with. What use is being able to fire Warp dakka and smash bug eyes without someone other than the ones you smashin' to see it?"
"I am already ahead of you," says Red with a smile, "While you were killing everything in sight, I was searching the Warp. While Orks don't appear in the Warp like normal beings, in large enough numbers, they do appear. I have found a large force of Orks nearby. Well, as near as anything can be in space. Most likely a WAAAGH or just a big ass group of Orks."
"Then what are we waiting for," says Killkrumpa standing up, "Let go introduce them to their new Big Boss."
Red appears on his shoulder and, raising her hand opening another Warp portal that leads to the bridge of the chosen Kill Kroozer, unleashing the Weirdboss on the galaxy.
