You'll soon discover that the Viridian City Gym has recently reopened, and the head trainer has issued an open challenge to all comers. Who could this mysterious trainer be, and where was he hiding? As it turns out, you know him pretty well already

With Blaine out of the way, only one more Gym remains. That's the one in Viridian City that has been locked up until this point. Inside waits your nemesis, Giovanni. His protegé trainers are no slouches, and seemingly easy paths around them are complicated by the special tiles that bounce you around like a pinball. Bring plenty of Potions and head back to the Poké Center if you take too much damage. And keep your eye out for a free Revive inside the gym.

After his defeat in Saffron City, Giovanni returned to his old job as the leader of the Viridian City Gym. Now that he's given up on crime, he'll gladly reward you—if you best him in battle that is! The hardest trainer yet? Not likely, since the same Water-type Pokémon that you trained to defeat Blain can walk all over Giovanni's Ground-types. In Blue and Red, a single Cloyster, Squirtle, or other high-30s level Water-type Pokémon can take everything Giovanni throws at you just by using Surf over and over again.

Things are a bit trickier in Yellow, with higher-level opponents and a Normal-type Persian tossed in to trip you up. Still, stick with Water for the other four and you'll do fine. Your prize is the final badge, the Earth Badge, and TM 27 (Fissure, a Ground version of the inaccurate, one-hit K.O. Guillotine attack). The Earth Badge ensures that Pokémon of any level will obey you.
