"I am Gene, the Master of the Rock Club! Rock is good...Isn't rock good, <player>...? Rock is hard and strong! Doesn't crumble under pressure! After you duel me, you'll know I'm right! Come! Show me what you're made of!"
No: "I have no time for a softie like you! Come back here after you've hardened your nerve!"
Yes:"Our duel will be played with 6 prizes! You won't get the Rock Medal unless you defeat me!"
"Wonderful... Your persistence - persistence that can even break rock - has led you to defeat me! You are worthy of receiving this Rock Medal! And take this booster pack, too. ...And another booster pack: Mystery."
3 Years on a Rock Deck (Japanese: いわのうえにも３ねんデッキ) is played by Gene. Defeating Gene in a 6 prize card match grants the player the Kabuto Coin. Additional prizes upon any victory are one Island of Fossil booster pack and one Beginning Pokémon booster pack. Players also have access to this deck in Auto Deck Machine 1.
At the start of the game, Gene was approached by GR1 when the player arrives, and unlike most of the other Club Masters, Gene was able to defeat GR1 and successfully defend the Rock Club. Players are required to battle Gene in order to be able to challenge GR1 at the Fighting Club.
Gene's deck in GB2, いわのうえにも３ねんデッキEven 3 Years on a Rock Deck, is a reference to a Japanese proverb; even a rock could be warmed if one sat on it for three years. The proverb is meant to teach the value of perseverance.
