The 16th gym leader is Blue, then after that, you get the EARTH BADGE, and get a TM from him after, then you are able to use HM08. After you go to Mt. Silver, your going to fight Red, who is similar to Ash, his Pokemon are lv. 80-90.

Blue is in Vermillion City in Kanto, the gym that is empty is where he is.
