Hello there, Skylinemaster here with a new fanfiction. This will be called the Leviathan of Halkeginia. Hope you enjoy.

"Summoning speech."

'Thoughts'

"Regular Speech."

Disclaimer: I don't own anything from Supernatural or Familiar of Zero.


The Leviathan known in the Human world as Dick Roman took out his frustration and anger out on the unfortunate Vampire in his path.

Dick punched the Vampire into a tree before stabbing his hand through the monster's chest as the Vampire went forward.

Dick retracted his arm and the Vampire slumped forward.

This is the seventh Vampire that Dick has killed since returning back to Purgatory yesterday.

Dick frowned as he remembered how the Winchesters and Castiel managed to kill him and send him back here.

Dick knew that Dean and Castiel were pulled in with him, and relished the opportunity to meet them again and kill them here.

He still needed to find them for his revenge though. As such, Dick made his way through Purgatory to find the Leviathans that are still here and resume his place as their king and absolute leader.

Since he was in Purgatory since the beginning of time, he knew the place very well.

He is following the river of bile that leads directly into Leviathan territory, and is killing anything unfortunate enough to get in his way.

His victims include three Gorilla-Wolves, twelve Werewolves, two Shapeshifters, and the seven Vampires that were just killed by Dick.

Dick contemplated traveling in his ooze form but then decided against it. It would alert the Leviathan that he was coming back, and he doesn't want that. He wants to see who dared take his spot as the leader of Leviathan. Dick rubbed his hands together at the thought of making said Leviathan bib itself as punishment for daring to usurp Dick's throne.

Dick walked along the river before stopping and frowning.

He is hearing a female voice in his head as he turned his head to see if anyone was near him.

Nope.

"My servant that existed somewhere in this vast universe…."

No one makes Dick Roman their servant.

…. my divine, beautiful, wise, powerful servant…"

Dick laughed as he heard divine. He is the possibly the worst mistake God has ever made and he knows it.

He did nod his head at beautiful, wise and powerful through.

"…..heed my call, I wish from very bottom of my heart and add to my guidance and appear!"

With that, a greenish portal opened up in front of the Leviathan leader.

'Interesting. Someone is powerful enough to summon me to Earth.'

A smile appeared on Dick's face.

"Big mistake."

With that, Dick Roman, the leader of the Leviathans, walked into the portal.


I hope you enjoyed this chapter.

I saw that there were no Supernatural/ Familiar of Zero crossovers, and I wanted to be the first one to write one. I thought it would be very interesting to see Dick Roman in a place with close to no technology, and especially no Winchesters to stop him.

Please follow, favorite, and review! Reviewing will tell me what you think of this, and what I should add to the story.

If the story is popular enough, I will attempt to update once a week. If it is not that popular, updates will be sporadic.

Until then, Skylinemaster out.
