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.

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.
• Cultural genocide - 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 and 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. Do not add it with Murderer either as genocide is murder on a larger scale and it would be redundant UNLESS the Villain is a Murderer who attempts genocide but fails.
