South of Pallet Town is a patch of grass on the shoreline, but after that the route stretches off into the ocean. To the south lie the ruins of Cinnabar Island.
Trainers with a telephone symbol by their names will give their Pokégear number to the player, and may call or be called for a rematch with higher-level Pokémon.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Cinnabar Island
The remains of Cinnabar Island
Sometime over the last three years, the volcanic Cinnabar Island erupted. The Poké Center was rebuilt since then, but the rest of the town was either buried in rubble or swept into the water. It is here that you meet Blue, contemplating the power of nature. He heads back to the Viridian Gym to await your challenge, but you need to defeat the Cinnabar Gym Leader first. Without a Gym, Blaine was forced to relocate to a cave in the Seafoam Islands to the east.

Route 20 is a short stretch of water that surrounds the Seafoam Islands. The islands were damaged by the eruption in Cinnabar; the west island is blocked completely, while the east island has been reduced to a single small cave. It is this cave that Blaine has taken as his temporary Gym.

Cinnabar Gym
Blaine's cave in the Seafoam Islands
Blaine's quiz machines were destroyed, so there are no puzzles here to solve. The Gym Leader is a Fire-type specialist, so you may want to bring a few Burn Heals. All three of his Pokémon are susceptible to Water- and Ground-type moves, but his Magcargo is especially vulnerable. Though his Pokémon are at respectable levels, they still shouldn't pose much of a threat. However, Water Pokémon should still be careful of Magmar's ThunderPunch.
Cinnabar Gym
Trainers
There are no Gym Trainers in the relocated Cinnabar Gym.
Continue east to explore Route 19, the final ocean route in Kanto.

By the time you return to the beach near Fuchsia City, the debris from the Cinnabar eruption has been cleared away. Defeat the few Swimmers here for some quick cash, then Fly back to Viridian to battle for your final badge.

Viridian City
Viridian Gym
Viridian Gym
Blue is the only Gym Leader that does not have a preferred type; instead, he uses the team he had during his time as Champion. He has the most diverse team of all the Gym Leaders, so defeating him is not going to be easy. Use Electric-type attacks to take down his Pidgeot and Gyarados, Water-type attacks for his Rhydon and Arcanine, and Ghost- or Dark-type attacks for Alakazam and Exeggutor. Restore your Pokémon's health often to protect against Gyarados' Hyper Beam, Exeggutor's SolarBeam, and Rhydon's Earthquake.
Defeated, Blue awards you the Earth Badge, the sixteenth and final badge.
Having defeated every Gym Leader in Kanto, you can now return to Pallet Town to tell Professor Oak of your adventure. As a reward, the professor arranges for you to venture into Mt. Silver, a large mountain that is off-limits to most Trainers due to the powerful wild Pokémon found there. To reach it, head west from Viridian to Route 22.
