Arctic Spawn are an organism presumably indigenous to the planet Arcterra in the Tetra Galaxy. They are psychrophilic by nature, and therefore actually require low temperatures in order to survive, let alone thrive. They are territorial to the extreme — likely because of being apex predators — and will attack any perceived threat by hurling immobilizing shards of razor-sharp ice, which are so cold that they can instantly freeze a foe.

For an unknown reason, they are in stark but nearly identical contrast to a similar creature known as the Fire Spawn, which may indicate that one or both species had been manipulated by the Alimbic before their mysterious disappearance. It has also been speculated that they have been exposed to some form of mutagenic substance, although it is not considered to be Phazon.
