Part 10: The eight Kanto gyms
Not a mission: the gym leaders can be fought whenever you reach them, and their teams (Lv 33 to 47) sit between Bill's and Lance's. Listed here so they fall in a sensible place in the level-cap table.
The eight Kanto gyms opens 6 areas. There are 20 trainers standing in them. The fights at this checkpoint are Brock, Misty, Lt. Surge, and 3 more.
