As far as supervillains are concerned, Marvel has some of the most well-known characters in the comics. From baddies such as Iron Man's Mandarin to Thor's Loki (who is one of the most popular at the moment, thanks to the MCU movies), or from big and well known cosmic threats such as Thanos to the more obscure one such as Molecule Man, Marvel has them all.

In this list, we are trying to find out who are the biggest threats out there, who are those top 10 supervillains who have made the entire Marvel comic book universe tremble. We are not talking about popularity, but about those supervillains who have such tremendous powers that they simply cannot lose in any kind of a fight.

So who are these guys? Who are these supervillains who make the Marvel superheroes give their best?

To be noted, just like any other comic book character, all of these guys have been defeated at one point or another, even by the least powerful heroes (or villains, for that matter). So we will take their most powerful avatars, those versions who wouldn't lose if it wasn't for some writers messing up with their storylines.
