The name of the serpent often associated with the end of the world in various mythologies is Leviathan in Judeo-Christian traditions. Similarly, in Norse mythology, the creature known as Jörmungandr (the Midgard Serpent) plays a crucial role in apocalyptic events, particularly during Ragnarök, the final battle. These serpents symbolize chaos and destruction, embodying the ultimate struggle between order and chaos. Their appearances in mythological narratives signify profound transformations and significant upheavals, often marking the end of an era or the commencement of a new one.
