Argus is a character in the Mortal Kombat universe who plays a significant role in the lore, particularly in Mortal Kombat: Armageddon. He is an Edenian god and the Protector God of Edenia.
Key details about Argus:
* Family: He is the father of three sons: Taven, Daegon, and Rain.
* Taven and Daegon are his sons with his wife, the sorceress Delia.
* Rain is his son with a mortal woman, Amara, an affair that Argus kept secret and for which he abandoned Rain. This abandonment is a major source of Rain's antagonism toward him and his family.
* Role in the Lore: Argus, along with his wife Delia, foresaw the coming of Armageddon, a final battle that would result in the deaths of all the realms' warriors. To prevent this, they created a plan involving their sons, Taven and Daegon, to either defeat Blaze or kill all the kombatants. This quest is the central storyline of Mortal Kombat: Armageddon.
* Status: In the original timeline, Argus is killed by his son Daegon. His death and his legacy continue to be referenced in later games, particularly through his sons' stories. In the new timeline established in Mortal Kombat 1, Argus is still mentioned and appears to be a Protector God, though his role and status have been altered.
