The Tsuchinoko originated in ancient Japan where it developed the unique ability to slip between worlds through impossibly narrow spaces, allowing it to witness the evolution of cryptid species across all cultures and time periods. After centuries of observation and accumulating the secrets of every known cryptid, it became omnipresent throughout the cryptid realm, appearing wherever cryptid hunters seek knowledge and occasionally revealing cryptozoological truths to those it deems worthy.

The Omnipresent Tsuchinoko possesses a distinctive thick-bodied, snake-like form capable of compressing to impossible thinness to travel between cryptid domains, leaving behind a faint trail of iridescent scales that briefly reveal doorways to other realms. Its venomous bite doesn't kill but instead transfers ancestral memories of cryptid encounters, causing vivid hallucinations that contain hidden truths about the cryptid world. The Tsuchinoko can speak all human languages and communicate telepathically with other cryptids, serving as both messenger and trickster throughout the cryptid universe.

The Omnipresent Tsuchinoko serves as the elusive keeper of cryptid secrets, appearing unexpectedly throughout all leagues to test worthy cryptid hunters by revealing crucial information or creating misleading trails based on its mischievous assessment of their intentions. Its constant movement between realms creates a network of knowledge that connects disparate cryptid species, maintaining the delicate balance of the cryptid ecosystem while ensuring their continued mystery to the human world.
