|Affiliated with:||Beth Smith|
|First seen in:||Big Trouble in Little Sanchez|
In the episode Big Trouble In Little Sanchez, when Jerry wears the Mytholog helmet, Beth's Mytholog is created. It is a giant insectoid, taking traits from spiders, scorpions, snakes and many other creatures.
Being very cunning, Beth's Mytholog creates a plan to escape from the Off-Planet Therapy Retreat (using Jerry's Mytholog). It then attempts to take over the world, being stopped after Jerry and Beth work out their relationship issues and create Ideal Jerry's and Goddess Beth (as well as Self-Congratulatory Jerry).
Beth's Mytholog is largly inspired by many creatures - most notably, scorpions. The tail is very scorpion-like, as well as having very rough, jagged skin. She also has 8 limbs.
- Mytholog Beth makes a cameo appearance in one of the Jerrygotchi mini games from the Rick and Morty Rickstaverse game. An 8-bit version of her appears in a nightmare of Jerry's, who subsequently urinates.
- She heavily resembles the Xenomorph Queen from Aliens and has four mandibles reminiscent of a Yautja from the "Predator" franchise, making her overall image a possible reference to the Predalien from "Alien vs Predator: Requiem.
