Who are the bad guys in World of Warcraft?

Answer 1

There are many characters in World of Warcraft that can be considered the bad guys, depending on your point of view.

Generally the Horde believes the Alliance to be oppressive and militant, while the Alliance believes the Horde to be uncouth barbaric rabble out to despoil the country.

In Classic WoW, the main bad guys of the story were the Twilight Hammer Cult (Elemementalists who seek the return of the old gods), the Qiraji (insect creatures under command of the old god C'thun) and the Black Dragonflight under command of Nefarian and Onyxia.

In The Burning Crusade, the main enemies were the demons of the Burning Legion, with highlights fighting Illidan, Kael'thas and Kil'jaeden.

In Wrath of the Lich King, the main enemies were the forces of the Scourge and the Lich King. The Old God Yogg-Saron also was an opponent, but seemed to be more of a threat to the side, dove-tailing with the Scourge.

Now, in Cataclysm, the elemental forces have combined power with Deathwing and the Black Dragonflight. This means the main opponents are the elemental lords (Al'aqir, Ragnaros predominatly), the Twilight Cultists under commands of Cho'gall and his master C'thun - and Deathwing as the main visible threat.
