Thorn beast



Thorn Beasts are used as food by the Covenant, and Jiralhanae in particular. They appear to be docile herd, and may have been domesticated for consumption. Their neck and head contain high concentrations of neurotoxins, likely a defensive adaptation against predators. While they are found on planets other than Doisac, Its popularity among Jiralhanae may show that it inhabits a variety of worlds, perhaps transplanted there by the Forerunners' after the Halo Array activated.

Thorn Beasts were originally meant to appear in Halo: Combat Evolved, but were cut from the final game. They finally make an appearance in-game in Halo Wars. The game developers state that they react to units and battles around them. In the videos seen so far however, they merely run away from units, not battles; if there is a bombing next to it, it will not flinch. However, since the videos were made as the game was still in development, this lack of a reaction may have been changed for a more real gaming experience. It's first canonical appearance was in Halo: Contact Harvest, where it is consumed by a Jiralhanae pack. In the book Contact Harvest it is described that Thorn beast is served back up showing it's five spikes and it's legs splayed though the head and neck is cut off (due to the high amount of neurotoxins).

Trivia

 * In Halo: Contact Harvest, it supposedly gets its name from the five "thorns" that ridge its back.
 * Because they are served as food, it is a possibility that they were kept at the agricultural ship Infinite Succor and perhaps the deranged, half infected creature seen by the Spec Ops Elites moments before being consumed by the Flood, was in fact a Thorn Beast.
 * The Thorn Beast's entrails could be reduced into dipping sauces.
 * Jiralhanae seem especially partial for the animal. Chieftain Maccabeus enjoyed eating the ball of muscle under the smallest of the five thorns that ridge its back when it was properly prepared, and the Brute Army Commander enjoyed it immensely. Given the Jiralhanae's enjoyment of the animal, it may be native to Doisac.
