8. Mephisto - As Old As 'Hell'
Mephisto is a demon based on the Faust legend, and with his place of birth being Hell itself (albeit not the Biblical Hell), the character has literally been around since the beginning.
Introduced in Silver Surfer #3, comics fans will recognise Mephisto thanks to his relationship with the Spirit of Vengeance, AKA Ghost Rider. The demon has had a long-running rivalry with Zarathos (whom he eventually defeated), and has been a staple of Marvel's supernatural scene for decades, dating all the way back to his first appearance the Marvel bullpen-era of the 1960s.
He's a darker trickster than Loki - the God of Mischief - and with the demon commanding such a massive influence throughout the occult, it's little wonder that he's become one of Marvel's biggest villains.
