Genocidal Villains are a step above your average Mass Murderer and a step below the Omnicidal Maniac; they seek to exterminate an entire race or species. They usually commit genocide to further their own race's (or species') power, fulfill some insidious political goal, or eradicate a particular race perceived to be practicing religious heresy. Or, they could simply view another race as a threat or commit genocide for their own selfish gain. In rare cases, there are various villains out there who commit or attempt genocide for fun or out of pure sadism. Thus, they have no real reason to committing genocide apart from taking pleasure in harming others.

Genocide has long been considered a violation of not just international law but also basic morality, making those guilty of participating in such acts extremely difficult to redeem; in spite of this, some Genocidal Villains may be praised by intolerant or misguided individuals who may not be aware of how far the villain is willing to go in their quest to "cure," "cleanse," "purify" or "fix" the world.

Genocide comes in some notable subtypes such as:

• Genocidal hegemony - Marked by a desire to be the sole surviving race, species, or faction in an entire planet, solar system, galaxy, universe, or even multiverse. Thus, they will target all other species for extinction in favor of their own, while a standard genocidal group or character targets only a few select groups in a society. Some parasitic species will even use other species as hosts by which to reproduce and effectively wipe out all competing life. Examples are Koba, the Daleks, Emperor Palpatine, Abaddon, Riot, and Commander Tartar.
• Ethnocide - The deliberate destruction of a people's culture, nation, and identity, as well as often, the enslavement of said people, who are annexed into the enemy ranks. Many evil empires, rogue A.I., or similar do this, and it is the only form of genocide that is not necessarily mass-murder, though it is still very much the deliberate destruction of a select group. Examples include the Borg, Syndrome, Kai Chisaki, and the Cybermen.

NOTE: Please do not add Xenophobes as not only is it obvious that they hate another group and it isn't for people out to kill the group despite seeing them as inferior.
