If Misty appeared in Advance Battle series involving Ash vs Juan, she should’ve visited Sootopolis City because it was a beautiful place especially for Water Pokémon. Juan and Wallace are from that city, and the former is Wallace’s teacher. Speaking of Wallace, he’s the Contest Master and hosted the Wallace Cup. Misty should’ve tried out this event especially meeting Wallace himself. Love to see her reaction to those famous Water Pokémon Trainers.
