Driftveil City Pokémon Gym Leader: Clay "The Underground Boss"
Pokémon Black and White
When the player first arrives in Driftveil City, Clay will be mad at them because when the Driftveil Drawbridge was lowered in order to let them into the city, a group of Team Plasma members Clay and his underlings had caught escaped. Thus, Clay only lets the player challenge the Gym once they've found and beaten Team Plasma at the Cold Storage.
The Driftveil Gym features a number of elevators that are in the mine shaft layout which must be navigated up and down and girders which need to be crossed to reach the central elevator, which will take the player down to Clay at the bottom of the mine shaft. There are five Trainers on the way down, though the player only has to battle three to reach the Gym Leader.
One of the Trainers in the Gym mentions that the depth of the Driftveil Gym helps to remind Clay that he once started at the bottom with nothing.
Pokémon Black 2 and White 2
The Gym no longer features the elevator puzzle, but is instead replaced by a conveyor belt puzzle that takes the player to landing platforms. Each time the player lands on a new platform, it lights up. Occasionally there will be viewing platforms, which allows the player to see several platforms from above. Whilst most of the conveyor belts take the player directly to the next platform in any one direction, there are some that jump a platform by traversing underneath it, leading to the one beyond it instead. This time, there are seven trainers available to battle in the Gym. However, only two of them need to be battled in order to reach Clay. As the player lights up more of the platforms, the ground becomes more visible, stalagmites of crystal can be seen jutting out of the ground, as well as air vents that connect all the way through the Gym, one of which can be seen next to Clay's golden platform. Various drilling machines, wheelbarrows and shovels also litter the floor throughout the Driftveil Gym.
The Driftveil Gym made its debut in The Mighty Accelguard to the Rescue!. However, only the outside of the Gym was shown in this episode due to Clay being too busy to have his Gym battle with Ash.
The inside of the Gym made its debut in Battling the King of the Mines!. Like in the games, the battlefield is located at the bottom of the mine shaft, requiring an elevator for access. Ash had a Gym battle with Clay in exchange for bringing him a bag of Revival Herbs from Milos Island. During the final round between Ash's Roggenrola and Clay's Excadrill, Roggenrola evolved into a Boldore, allowing Ash to win the match and earn himself the Quake Badge.
Pokémon used in Gym
Krokorok
Clay's Krokorok first appeared in Battling the King of the Mines!, where it was used to battle Ash's Oshawott. At first Krokorok used dust to blind Oshawott, allowing it to land many successful hits. However, finally Oshawott was able to clean his eyes with his own Water Gun and then defeat Krokorok with Razor Shell.
Clay's Palpitoad first appeared in Battling the King of the Mines!, where he was used in a Gym battle against Ash. He easily defeated Ash's Oshawott, after which he battled with Snivy. Snivy started by using Attract on Palpitoad, which became infatuated, thus making him unable to attack and an easy target for Snivy, which hit him with all of her attacks and finally defeated him with a Leaf Storm.
Clay's Excadrill was used in a Gym battle against Ash's Snivy. It was easily able to block all of Snivy's attacks and then knock her out. Next Ash used Roggenrola. Thanks to its AbilitySturdy, Roggenrola could avoid being knocked out by Excadrill's Horn Drill. Later Roggenrola evolved into a Boldore and defeated the Subterrene Pokémon with its newly learned Rock Blast and Rock Smash attacks, despite being at a major disadvantage.
The Driftveil Gym appeared in Mine Mayhem and Underground Showdown, where Black challenged the Gym. Due to all the Gym Trainers being away at the time, Black was able to reach Clay at the bottom floor of the Gym without any difficulty. During the Gym battle, Clay told Black how he had heard of him from the other Gym Leaders, and how he had some time ago discovered the Dark Stone while digging at the Desert Resort. While battling Clay's Excadrill, Black's Nite accidentally sent a rock flying at the power box, shutting off the lights. This gave Clay's last Pokémon, Krokorok, an advantage over Black's final Pokémon, Costa, as it had the ability to sense the body heat of its target, even in the dark. Using himself as a decoy, Black gave Costa a chance to attack and defeat Krokorok, winning the match for him.
Trivia
One of the Trainers inside the Gym says that Clay is a company president. It is not known what business Clay actually owns.
In the English versions only, two Trainers (Isaac and Felix) share their names with main characters from the Golden Sun series, who are both associated with the element of earth.
In Black 2 and White 2, this is the only Gym in which Trainers that were not fought can be battled after the Gym Leader has been defeated.
