7. Dr. Doom
I've heard people call Dr. Doom the greatest comic book supervillain of all time, and when you look at his track record, it's pretty hard to argue.
Victor von Doom was a little Romani boy from Latvaria whose mother died in a botched deal with the devil. Like, the literal devil, or as close as Marvel comics comes to the literal devil. Victor was offered a scholarship at State University in New York, where he met Reed Richards and Ben Grimm. He then settled on his ultimate machine: a device that could let him visit Hell and save his mother. Reed tried to warn him about a miscalculation in his plans, but Victor ignored him, and the machine exploded. It ruined Victor's face and got him expelled.
Victor next went to Tibet, where a group of monks built him a suit of armor that would cover his destroyed face. After this, Victor, now christened Doctor Doom, returned to Latvaria, and conquered it.
Doom fought the newly formed Fantastic Four numerous times, using his skills in science and witchcraft to devise new master plans. He also stole ultimate power multiple times, first stealing the Power Cosmic from the Silver Surfer and later taking the Beyonder's reality warping abilities. Dude also took Thor's hammer once.

6. Loki
I mean, come on, how was I gonna leave a Norse God of Mischief off this list? Loki was crazy powerful.
Odin adopted Loki, son of frost giant Laufey, as his son, to be raised alongside Odin’s biological son Thor. Loki didn't like Thor. Especially how everyone else liked Thor's bravery and combat skills, which Loki lacked. Loki decided eventually that God of Mischief wasn't enough, and took the formal title God of Evil, which was a step up. He also spent a ton of time trying to murder Thor. Just so much time doing that. These schemes and flim-flams eventually got him turned into a tree by Odin as a magical means of saying, "Hey, knock it off, maybe?"
Loki was eventually freed, and he kicked off a long career as a supervillain. He caused the formation of the Avengers, tried to team up with Dormmamu to pit the Avengers and Defenders against each other, and even helped Odin and Thor repel Surtur during his siege on Asgard for the Twilight Sword. Loki died in Ragnarok, but came back as a lady. She teamed up with Norman Osborn's Cabal during Dark Reign, died, and was reborn as a young boy who joined the Young Avengers and fought for good, minus his older self's dastardly influence. Well, for a time, that is.
