I do not own anything. All characters belong to their rightful creators.

So this is a Harry/SLASH crossover series of one shots.

Koldy wants - Harry/Lucifer (Supernatural)

It was so easy, Harry mused, to steal away the Winchesters' pet. They were so focused on trying to keep themselves from becoming vessels that they had neglected the safety of their friend. The angel was surrounded by holy oil, again, and at the mercy of Harry and Lucifer.

"Come now, Castiel," Harry grinned teasingly at the fallen angel. "Do you really think Sam or Dean are going to risk their necks to save you?"

"I am their friend." Castiel jutted his chin out stubbornly.

"You hear that, Lucifer?" Harry looked over at his lover with a smile. "He thinks that the Winchester boys are going to save him." Harry turned back to their prisoner. "Deany-boy isn't going to let his baby brother anywhere near Lucifer, not that Lucifer needs Sam, anymore."

Castiel's head jerked up. "What do you mean?"

Harry giggled.

"Magic is an incredible thing." Lucifer spoke up, stepping out from the shadows. "Especially when wielded by my lover."

Castiel's eyes widened as he caught sight of the Devil's vessel. No longer was Lucifer's host degrading, instead it looked new, as if the human was made for him like Sam was.

"Impossible." The word slipped out before Castiel could stop it.

Both Harry and Lucifer laughed in delight at the horror and disbelief that was now shining out from sapphire blue eyes. Harry danced over to Lucifer's side and tilted his head up expectantly. The fallen angel chuckled and obliged to Harry's silent demand. He dipped his head down and pressed his lips against Harry's, his tongue licking against the seams of the wizard's mouth where the latter eagerly gave in and allowed Lucifer entrance. Harry mewled and molded his body against Lucifer's, enjoying the domination.

Finally, after several long minutes, the two pulled back, and Lucifer turned to Castiel with a grin.

"Do you really think that God will do anything? Or the Winchesters? Or Michael?" Lucifer's grin darkened. "I have the master of death by my side, little brother."

Castiel's eyes widened, and his head shot back round to Harry who gave him a low bow.

"The master of death?" Castiel's face was pale, and it was only by staring into his eyes, that Harry could gleefully detect the flicker of hopelessness and was that... defeat? It was delicious.

"Yup." Harry clapped his hands together. "Surprise!"

Castiel closed his eyes and turned his head away.

"Aww, Cass, don't be sad!" Harry pouted, dancing around the ring of fire. "It's not all bad. I mean, yeah, humankind is going to be obliterated, but the planet will still be here. The animals that your father created, and all the beautiful variety of plants. That has to be some comfort. No matter how small."

"You think that wiping the world of humans that your life will be better?" Castiel suddenly snarled. Harry mentally applauded the angel for finally showing a backbone. "What happened to you, what did they do to you that was so awful that you would rather see them all slaughtered?"

Lucifer took a threatening step forward, a glare in place. Harry shot him a warning look, a hand out to halt the devil's movement. Harry took a deep breath and met Castiel's infuriated gaze.

"You want to know?" Harry asked. Castiel blinked at Harry's change in mood. "I'll tell you. I'll tell you about how I was betrayed by the people I loved and trusted the most because of their prejudice. Of their fear and hatred for things different from what they believe is normal." Harry's hands curled into fists. "As a child I was hated because of my magic. Then I was hated because people and their flaw to jump to conclusions. At the time completely false. Then jealousy, and presumed assumptions of what I should be like because in their minds, they have built up an illusion of what they think I should be like." Harry's mind flashed to Lupin and Black. "And when I finally saved them all from being tortured and murdered by a group of psychos, they turn on me yet again, because of their fear of my power. They started to hate me again for something I couldn't control."

"So you're punishing them." Castiel concluded.

Harry blinked, reigning back his emotion.

"They feared me because they hate the thought of something being more powerful than themselves. So I'm giving in to their needs for that." Harry laughed coldly. "I will kill each and every one of them. I will make their nightmares of me come true."

"And I will help." Lucifer finally stepped in, placing a hand on Harry's shoulder.

"Not all of humankind is like that." Castiel said. "Don't destroy the whole race because you have experienced pain from a group of them."

"You are too blinded for you love of your father, your faith, that you cannot see their greed. Their hatred for everything different." Lucifer scolded.

"And you cannot see their compassion or loyalty, their capacity to love." Castiel shot back. "I can. I am not blinded by resentment."

"We are not the ones blinded, brother." Lucifer cocked his head. "It's too bad, you seem to hold such promise."

"Too bad it;s all wasted on the humans." Harry added, wrapping an arm around his lover's waist.

"You were once human," Castiel pointed out.

"I was." Harry conceded. "But then I became the Master of Death. No longer human, but near immortal that has control over the four horsemen. Which I will have once again put together since the Winchesters sent two of them into catatonic states."

The satisfied look that crossed Castiel's face just then almost made Harry want to lash out with his magic, but a whispered command from Lucifer forced Harry to reconsider. Lucifer looked back to Castiel, and stared him in the eye.

"The rings the two idiots have will become null and void once Harry recreates new ones." The dark fallen angel explained. "The magic and power within them will disappear, making them nothing more than normal, everyday rings."

"That's not possible." Castiel said, eyes wide. "The rings of the horsemen hold their power, you cannot simply take that away from the rings."

"I can." Harry smiled darkly. "And I will. The Winchesters cannot kill me, Lucifer does not need Sam, and we both will eradicate this earth."

"I am sorry, little brother." And Lucifer actually did sound sorry. "But you are either with us, or you're with the humans."

"I will never join you." Castiel declared.

"Then in which case I cannot let you live."

Harry turned his head and gave Lucifer a reassuring kiss to the jaw before skipping back. As much as he now wanted Castiel dead for rejecting his brother, Harry didn't want Lucifer to hurt. And killing Castiel is something they both had wanted to avoid.

A pain-filled scream cut through the air, followed by a flash of blinding white light, forcing Harry to cover his ears and close his eyes. It was for the best, Harry thought, if they wanted to save the world from the parasitic creatures that contaminated it.

How about this? And I know that I have killed Castiel in this one *Ducks and hides behind desk* but that's where my mind took me. I love him really!
