The Interdimensional Rift is a wormhole and the byproduct of combined portal fluid from The Citadel during Evil Morty's escape from the Central Finite Curve. It was later seen spawning inter-dimensional worm-like monsters when Summer, Beth, and Space Beth raid The Citadel and was finally fixed by the Dinosaurs after Rick caused them to destroy a meteor. It first appeared in "Rickmurai Jack" and last appeared in "JuRicksic Mort".
