Dire Beasts

Dire Beasts are mutated breeds of otherwise mundane animals that have grown to massive proportions. They are usually hostile towards other creatures outside their current and original species and possess intractably foul temperaments that make their domestication a herculean task.
First-generation Dire Beasts generally arise as part of a single brood from a normal mother of their base species. While born at sizes one would expect for their base species, they quickly grow to their dire builds, even without access to nutrition adequate enough to support their abnormal size. Dire Beasts can then inbreed for a generation or two to achieve a sustainable population size, but these second-generation beasts are subject to increased caloric demands; however, they still require less food than regular animals of similar size. While not always physically possible by natural means, if a Dire Beast does manage to mate with a non-dire member of their original species, all offspring born from that coupling will be first-generation dire beasts.

Some Dire Beasts of transcendental potential are able to mutate beyond their original mutations and become Dire Dire Beasts, also known as Double Dire Beasts. These beasts arise as individuals as part of an advanced-generation dire brood.
