Question: pokemon sword and shield how old is marnie?
Answer: where is her age stated? You have to be at least 10 to go on a pokemon adventure but the main character and all the rivals look like they're teens (you can't convince me a 10 year old is that tall) so I've guessed around 13. I believe around 13 or 14 is the general guess. Somewhere around 13 or 14.
