Kirin appear to be capable of surviving in any environment. The known habitats of Kirin in the Old World consist of the Snowy Mountains, Old Jungle, Jungle, Old Swamp, Battleground, Tower, Tower Summit, Jurassic Frontier and Everwood.
It is unknown how Kirin fit into the ecological niche, however, they are known to be the natural prey of Rajang.
Kirin have white fur used for picking up electricity. When enough electrical currents are picked up in the fur, Kirin will glow brightly and its hide will deflect most attacks. From this, the Hunter's Guild believe that Kirin's high metabolism helps it pick up electricity as well. A Kirin's most vital feature is its long horn. This horn is used to summon lightning from the sky, even when there isn't a storm cloud in sight, to strike any foes that threaten it. However, even if this horn is destroyed, Kirin can still summon lightning bolts with little effort.
Some of the more rare, older, or just stronger individuals are known for having unusually strong electrical powers that are yet to be fully understood. Some of these extra-rare Kirin are able to harness bolts of red thunder much like the equally rare White Fatalis when feeling threatened. Some of the larger, more stronger muscles are located in its legs, capable of delivering deadly kicks. Equipped with such powerful legs, all Kirin posses the ability to run at speeds so unexpectedly fast they appear to teleport, leaving behind a trail of blue electricity. The strongest ones can do this 3 times in a row in a red thunder rage before its horn loses its red charge again.
Kirin are a highly unpredictable species. Sometimes Kirin are calm, other times they are aggressive. In one legend, it was said that a Kirin actually destroyed a whole village with its electrical powers.
