Having now explored nearly all of the Kanto region, it is a good time to tie up any loose ends, the most important of which is the Power Plant. To get there, fly back to Route 10.
Route 10
To reach the Power Plant, use Surf to follow the river southward past the Rock Tunnel entrance. It is only a short distance away, with a single PokéManiac outside the building.

The Power Plant is an industrial complex that was abandoned years ago, though some of the machinery still works. Many forgotten items can be found lying around, but beware: some are actually Electrode that only look like items.

Pass through the entrance room to get a Max Potion. Continue in a clockwise direction to the large, central room to find TM17 (Protect) and an Elixir. Collect TM25 (Thunder) in the southeast room, then follow the narrow hallway northward. Grab the ThunderStone from the northeast corner of the northeast room. Continue westward to reach the final room.
VS Zapdos
Zapdos is the last of the legendary birds that you will encounter. Use Rock- and Ice-type attacks to weaken it quickly, then follow up with Grass, Flying, and Fighting moves to wear its health down further. Like with Articuno and Moltres, it will be useful to cause status ailments like Sleep to increase the odds of catching it.
In the time it took to collect the seven other Badges, the Gym Leader of Viridian Gym has finally returned. Giovanni resumed his position as Gym Leader shortly after his defeat in Saffron City. The Viridian Gym specializes in Ground-type Pokémon. Grass-, Water-, and Ice-type attacks will be the most useful. Flying-type Pokémon are immune to Ground attacks and Flying moves will deal serious damage to the several Fighting Pokémon inside. Psychic moves will work wonders against Poison-type Pokémon.
Like the Rocket Hideout in Celadon City, the Viridian Gym also employs spinner tiles to confuse and disorient any challengers. Go north through the center room. Battle Ace Trainer Warren and Black Belt Takashi, so that Takashi walks away from the north wall. Return to the entrance and follow the spinner tiles north and west to reach the Gym Leader.
After the battle, Giovanni awards you the Earth Badge, which ensures obedience from all Pokémon, regardless of level. As a prize, he also gives you TM26 (Earthquake), a TM he claims to have made when he first acted as Gym Leader. He seems remorseful of his actions, and officially disbands Team Rocket before disappearing.
The Path to the Summit
Having won all eight Gym Badges, the next destination is the Indigo Plateau, far to the northwest. The elite Trainers there are tough, but before you can challenge them, you must first survive a grueling cave known as Victory Road. Gather your strongest Pokémon team with access to Surf and Strength, and visit a Poké Mart to replenish your supply of Potions and Poké Balls.
