A Hostile Species is an entire race of evil creatures and/or entities, common in sci-fi and fantasy genres. Some later redeem themselves, and some individuals within a species may differ in their beliefs. Sometimes Hostile Species with hierarchical structures, multiple races with common goals, and/or imperialistic tendencies can be overlapped with Evil Organization category.

They are also difficult to defeat if, despite being naturally hostile, sadistic, dangerous, xenophobic, or genocidal, they are capable of having children or making families; thus, killing a hostile species that is capable of reproducing naturally would still be considered an act of genocide.

• ONLY ADD RACES, SPECIES OR GROUPS OF ENTITIES to this category. Individual villains never count. They are never be able to be morally ranked (Due to the Villainous Benchmark Wiki recently now banning Hostile Species) because they all do the same or similar things, making them unable to stand out from each other, which keeps them from being (VB, IH, NPE, or CM). Also, since hostile species are a kind of team, groups of hostile species do not have moral agency (even if individual members of the species meet the criteria) meaning only said individuals can be ranked. The only exception are certain Hive Mind Species.
• Since Hostile Species refer as groups, should a particular species wants all, apply imperialist category instead of hegemony.
