The ursadon thrives in the snowy frozen wastelands of Braxis, and possess no natural enemies. These carnivorous animals hunt in the icy water for food. Instances of attacks on humans are rare, but the few recorded instances of an enraged ursadon attack have always ended in tragedy. The Koprulu Wilderness Society recommends keeping a safe distance from ursadons, for the safety of both the observers and the animals.
Ursadons can resist "flash freezes", which are found on some planets they live on, such as Kaldir.
Ursadons have been found on a dark moon that Dark Prelate Zeratul encountered on one of his journeys. Three were subjected to experiments by Clandestine Mercenaries, causing a broodling to emerge from one of their stomachs upon death.
During the Second Great War, a protoss base on Kaldir, a planet where ursadons could be found, was attacked by the zerg. In order to avoid the flash-freeze effects, Sarah Kerrigan ordered her troops to slay an ursadon matriarch and use its DNA to enhance her zerg ability to withstand the extreme cold.
Ursadons are the only critters in StarCraft to leave a corpse.
Ursadons can "leap" down cliffs. They became especially aggressive during flash freezes, and packs of them will spawn and attack protoss and zerg indiscriminately.
The ursadon charges towards nearby enemies. Can be set to autocast.
- In order to access the free minerals/gas cheat in StarCraft 64, the player must surround an ursadon which asks for a "hug" with his units.
- The ursadon is also a popular critter in tournament maps - one is usually included on them. Tournament commentator Nick Plott has nicknamed the ursadon "pandabear guy" - the name has stuck quite persistently.
