Yibb-Tstll is one of the Old Ones, ancient deities from beyond the space-time continuum.[1]


At an unspecified point in time, the Ghostbusters fought Yibb-Tstll and stopped it from destroying the world.[2] It went into hiding underground and waited for its next opportunity.

Vladimir Pavel Maximov and his assistant Dmitri Smerdyakov planned to summon an Old One using The Nameless Book.[3] Vladimir was promised by Yibb-Tstll he would become ruler of Earth.[4] In order to keep the visiting Ghostbusters from interfering, they stole the book from a Soviet institute, and blamed the Ghostbusters. Meanwhile, Vladimir and Dmitri met up with an Old One Cult miles outside of Dnepropetrovsk to summon Yibb-Tstll from a secret underground temple thousands of years old.

Fortunately, the Ghostbusters made it to the Yibb-Tstll's lair and were able to stop it before it completely made it to the surface. Slimer was sent back home to get "Big Trouble", a huge apparatus that uses the power of all the Proton Packs to create a rip in space-time, like a black hole, to absorb everything it touches. Peter Venkman bravely threw Big Trouble into the pit and ran way as he saw Yibb-Tstll reveal its hideous form. Big Trouble activated and sent Yibb-Tstll back to where it belonged.
