>>39601901>probable scenarios:As far as I remember, when a character highlights an unknown pokemon with the pokedex, the dex itself is usually what tells the person the name of the pokemon. Maybe the dex is either being updated constantly by researchers across the globe that have already named the species and it's just rare. Or, maybe the dex is scanning the biological entity and assigning it a scientific name based on the organism's defining traits.
>actual scenario:It's a show/game/series/etc. made for 10 year olds so nobody actually cares or thinks about this stuff.
