An Archenemy is the main enemy of the protagonist. The reason why the particular villain stands out more than the rest varies; they may be the hero's strongest enemy, be the complete antithesis to the hero, have strong connections with their hero's past, pose the greatest threat, or may be the most recurring villain like the Big Bad or the Right-Hand enforcer or even the Rival. They can also be an enemy to other villains, leading to an evil vs. evil conflict.
