I love the idea of Symbiotic Pokemon partners, two different pokemon species that have found a way to work in tandem with one another like Slowpoke and Shelder or my own Sunny the Charmander and Noctis the Gastly. I wanted to come up with more possible symbiotic pairs as well!

As a Poison type, Bulbasaur is immune to the Toxins of Glimmet who can sit comfortably within the hole of Bulbasaur's bulb. Bulbasaur can protect Glimmet from water type pokemon and glimmet can protect Bulbasaur from Fire type pokemon.
