Giovanni

Gym Leader of Viridian City - Ground-type specialist.

Team (Pokemon Yellow):

Reward: Earth Badge and TM27 Fissure.

Badge effect: Earth Badge is the eighth and final badge. With all eight, the Route 22 and Route 23 guard posts let you through to Victory Road.

How to beat him or her: The Viridian Gym Leader is GIOVANNI, the boss of Team Rocket - this is your third and final fight with him. Water, Ice and Grass hit his Ground team hard; Rhydon takes 4x from both Water and Grass. Lapras with Surf and Ice Beam is the star. Bench Pikachu entirely - Electric does nothing to four of his five Pokemon.
