After returning back to Hammerlocke with the Ballonlea Gym now defeated, you will next head towards Route 7 (after running into Bede). However, on your way to Route 7, you will run into Hop, the first time you've seen him since your battle in Stow-on-Side. Now finally having caught up to you, Hop feels it's the perfect time to have another battle. He team has changed dramatically once again, featuring even more Pokemon that he has never used before. Should you defeat him, Hop will tell you that he knows he's getting stronger (just not as quickly as your trainer).
