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!

This poor Riolu lost an arm, so their friend Beldum was willing to offer itself as a prosthetic. Beldum usually bond with other Beldum to form the arms of Metang, but as a Psychic powers it's not impossible that they could sync their mind up with the mind of their partner and move as though they are one. Riolu currently has a smaller range of movement in their new arm but it's sturdy and offers the benefit of Psychic powers to the little fighter.
