Even in Pokémon, there are lions. They follow me everywhere :D
But anyway.

Levina and her first, as well as the main, Pokemon, Shinx (I don’t know yet whether she will give him a nickname or not).
They have a very strained relationship, the lion cub does not always obey her, but does not harm Levi, like Pikachu to Ash. The first time he traveled with Levina, he preferred to spend time in pokeball and appeared out of great need (battle / pokemon catching / helping his trainer etc). Also, for a very long time, Shinx carried out the "instructions" of the girl's father: to protect her, monitor safety and help. Therefore, he did not immediately ignore them and realized that it was possible to be friends, and that Levina loved him very much.
Also, Shinx is strongly irritable and often dissatisfied with something, however, with Morton and her other Pokémons, he is more affectionate and calm.

P.s. yeah, I moved away from the anime drawing of Pokemon and decided to add my own style "a little".
