It was a cavern: dark, musky, water dripping off the stalactites that lined the ceiling. Goku and Vegeta, our clown and our prideful, stuck-up… I mean, our two intrepid heroes, were carefully walking between the stalagmites that littered the ground.
"Hey Vegeta, do you notice how some of these pointy things are broken at the top?"
"Amazing Kakkarot, for once you made a useful observation. Yes, now I see the pattern. Hmm … it appears as if they were all broken off at an even level."
"Yeah, like something really big and huge just stepped on them all!"
"Yes, Kakkarot," Vegeta sighed. "Yes."
The two saiyans continued their walk through the dimly lit cave, their only source of light coming from several Ki balls they kept hovering around them.
"Vegeta, why is there a wall right in front of us?"
"It's not a wall, Kakkarot. It's some type of structure. Send a Ki ball up towards it. Do I have to think of everything for you?"
"Right Vegeta," Goku said, ignoring the Saiyan Prince's taunt. A Ki ball zoomed away from the small group that was hovering around them to go and explore the structure. It was a midnight black color, and was extremely large. It was shaped somewhat like a pyramid, but with numerous encampments in the structure for weapon platforms.
"What is it, Vegeta?"
"I don't know, Kakkarot. But there is an opening over there. This structure has piqued even my curiosity. Let us explore."
Several minutes later, after flying up into the opening, the duo was walking along a straight hallway. There were numerous outcroppings, however, each one seeming to blend into a side of the walkway. Within each outcropping was a faint green light, almost like a nightlight. Curiosity getting the best of him, Goku went over to one to investigate it.
"Look Vegeta. There are things in there. They look almost like humans. But they're metal. Ahhh! They are androids!"
"Idiot, they are normal robots. They don't look human enough to be androids. Besides, they all appear to be offline."
Of course, with that statement, Murphy's Law came into play, and as Goku and Vegeta turned away from the outcropping to continue their exploration, the dull eyes of a Necron warrior started to light up. Intruders had bypassed the Monolith's defense system. Intruders must be eliminated.
"Vegeta," Goku said, trying to start up a conversation again. He was getting bored walking through all these hallways, and they all looked the same.
"What Kakkarot!?"
But whatever Goku was going to say was stopped by the clinking of metal on metal. Turning around, the two Saiyans saw a horrifying sight. Approaching them stood a Flayed One, his robotic body covered by the skins of his deceased enemies.
"That's just gross," said Goku.
"Hmmpph. I'll just blast it." Vegeta charged his palm with Ki energy and let loose. Seconds later, all that remained was scrap metal.
The celebration was ended, however, by a feeling of dread. It was as if death was approaching, as the air temperature lowered and a feeling of gloom arose.
"Vegeta? What's that feeling? It's wrong. Even worse than Frieza."
"Yes Kakkarot. I feel it too."
As the feeling of dread increased, a dark individual emerged from the shadows. Cloaked in darkness, the being approached the fallen Necron. Pulling out a staff from within the shadows, he smashed it on the ground, unholy green light arching out towards the broken Flayed One.
Remains glowing, the pieces started retaking their form, coming together to reconstruct the Necron's body.
"That is just wrong." Goku said, as the fallen warrior stood before them once again. "This whole place is evil. I feel it."
"Going to let me blow it up, Kakkarot?"
"No Vegeta. I need to use a spirit bomb. Its pure energy is the only way to permanently erase this taint."
Charging up a Final Flash and blasting through the ceiling, Goku and Vegeta flew up into the air to prepare a spirit bomb. Looking down upon the Monolith, they could see its systems reactivating. Ancient weapons powered up and shields reactivated as the Life-Destroyers prepared to fire upon the Saiyans.
"Now Kakkarot! Now!"
"Alright … Vegeta!" shouted Goku as he released the Spirit Bomb. Powered by not only whatever life had regrown on the current planet since the Necron's last culling, but also by surrounding stars and solar systems, the Bomb blasted through the Necron Monolith, wiping out their plague.
"Ready to go, Vegeta?"
"Yes Kakkarot. Although I am a little disappointed you were the one who got to blow it up. I need to stay in shape, otherwise I will never be able to beat you!"
"Don't worry Vegeta, I have this strange feeling we'll be getting home sooner than later."

AN: Well, as that last line might hint, the next chapter will be the last one. I'm running out of alien races to use, so I've decided I should just send the duo home. After all, it needs a happy ending! Well, maybe not, as I'm writing this I'm remembering I forgot about the Inquisitors and the Space Marines. After all, who doesn't want Vegeta to feel the 'wrath of the righteous.'
