>>44806686Technically Steven having Alola Sandslash makes sense because it's Ice/Steel type so it is on brand for him in terms of his theme or typing. Rotom is an Electric type primarily, so Elesa using one isn't unusual.
Rosa and Lyra are player characters, so they're not married to the type of their Starter. Also Cynthia as a champion doesn't have a particular typing to use, so Kommo-o isn't that random.
Usually it's the moves the sync pairs are defined by, so it doesn't necessarily mean the Pokémon's full type is represented in the game or contrary to the trainer's type specialty.
