Several generations ago, a small group of Kroot was mistakenly left behind on a uninhabited planet that was lush with jungle life. Though uninhabited by sentient beings, the jungle was teeming with lizards of all sorts, many of them huge, deadly, and aggressive.

Forced to defend themselves, the Kroot killed and ate many of the giant lizards that attacked them. The Kroot soon came to rely upon the lizards for food. Over the generations, a select group of Kroot slowly began to evolve in order to adapt to this new world.

These newly evolved Kroot were excellent at hunting down and fighting off the local lizards. Now, the Razorback Hound serves as a vital part of this marooned Kroot colony's survival.
