European Version of Apep/Apophis

Anyone one know if there's a European version of Apep aka Apophis. He's kinda like the God of Oblivion in Egyptian mythology, the God who's warded against, rather than prayed to. Ancient Egyptians, it seems, wanted to appease him to stay away, rather try and gain his attention. (Unless they were trying to sic him on their enemies...)

He's different from Set who is the God of the Desert, desolation, and death. Basically, Set is the opposite of Osiris and Horus, the gods of the fertile Nile Valley. Osiris and Set are pretty much different sides of the same coin.

Basically, I"m looking for a God that people are trying to avoid, such as is the case with Apep. Or if they do leave offerings, they're trying to buy the God off in order to leave them alone. I'm not looking for Gods of Death. I already know several that I can look up.

I just need a name and the Pantheon they're a part of to point me in the right direction. Greek or Roman will do but I rather have European, for my story.

For the record - I am not looking for the Christian Devil. There's plenty of works on the Devil or Satan, etc. I'm looking for something from European mythology or Pagan point of view.

Yes, Nordic, Germanic, Spanish, Portugese, Celtic, Romanian, etc. Greco-Roman mythologies tend to be classified as a group unto themselves, rather than with other European mythologies. I didn't want to say non-Mediterranean because I am interested in Spanish or Portugese mythologies.

Um, no, I'm not really looking for trickster gods, any more than I'm looking for gods of death. Gods like Hel or Annwyn ruled over places where spirits go after death. So in a sense, spirits still go someplace after death. Loki was a trickster god and caused trouble but he also tended to help clean up the mess afterwards, more often than not.

But it could be a monster. Basically something you don't want to attract the attention of because it's considered a destroyer of worlds or bringer of oblivion.

Thanks, all! I wasn't expecting to find a one-to-one match but the Chaoskampf sounds like a good starting point. And from what I read, there were some spells or incantations that humans used to appease Apep so he'd leave them alone. Or help leave Re alone.

Anyway, I'm looking for a god/force/monster that my villian is in the process of trying to recall back into 'reality'. The mages in my WIP are descended from old pagan priests. My villian learned of a grimoire that he thinks is from his family's past. He thinks he can use the grimoire to his advantage if he can get his hands on it. But the grimoire is from one of my MC's family and contains spells to keep a totally different entity under wraps, this Destroyer/Chaos entity.
