Secret Pokémon Campaign
Dr. Grant Hammonds
Dr. Grant Hammonds is the Pewter City Gym Leader.
David’s Assessment: Dr. Hammonds is a surprise for many trainers, they are expecting a rock type gym, then here comes rock water types and a rock flying. I would highly suggest bringing a grass type to this gym to deal with the Omanyte and Kabuto. Grass type moves will clear those two incredibly quickly, then all you have to do is deal with the ringer. Grass is less effective vs. Aerodactyl, for him I would suggest water, rock or ice types.
