Welcome back to Humor Nation. Through the fifteen seasons of the show, “Supernatural” has featured memorable villains. While the storylines of the show captivated the attention of the fanbase, nobody can forget the amazing villains that managed to leave an everlasting mark in the SPN Universe. From cosmic beings to angels and demons, there were all sorts of villains, each bringing a unique flavor of chaos to the show. While every fan has their take on who the greatest Supernatural villain is, undoubtedly, some villains will always be in contention, such as Azazel, the sinister yellow-eyed demon who set the events in motion by striking a deal with Mary Winchester. He was the loyal general of Lucifer who plotted and schemed to free Lucifer and make him strong in the war against the heavenly angels.
Although the character of Lucifer arrived in Season 5, he managed to convincingly play the role of a formidable adversary of the Winchesters. Although there have been times when he teamed up with the Winchesters, showcasing how complex the character truly is. Despite the majority of the villains overpowering the Winchesters and teaming up using their sheer strength, Metatron is one villain who used his intellectual prowess and manipulation to exploit others. Metatron was the Scribe of God, who tricked Castiel into casting a spell that would cause the fall of the angels. He did it to exact revenge from the angels and ascended to the throne.
While angels and demons have been the villains for the most part, Season 7 saw an unconquerable villain in the face of Dick Roman, the leader of the Leviathans. When Castiel absorbed all the souls of Purgatory, he also ended up containing the ancient monsters known as the Leviathans who refused to go back to Purgatory. Even though many fans feel Season 7 was the lowest point of “Supernatural,” Roman surely brought an arrogance that defied the Winchesters at every turn.
Season 11 saw the arrival of Amara, the Darkness who has the level of power equal to Chuck AKA God. Amara was imprisoned by Chuck and the archangels. Since Dean freed her, she shared a unique connection with him, both of sharing a level of vulnerability around each other. She vowed to destroy all the creation of her brother and to an extent, she caused some damage and consumed the souls of humans. Chuck and Winchesters had to enlist the help of Lucifer, Rowena, and Crowley to deal with her.
