"I am Nikki, the Grass Club Master. What? You were looking for me? Oh my... I'm very sorry to keep you waiting. I was doing a little research here. I assume you would like to duel? I only duel at the Club. I'm sorry, but could you meet me at the Grass Club? I will head back to the Grass Club and I wait for you there."
"I'm Nikki, the Master of the Grass Club. I'm sorry I kept you waiting. Shall we duel?"
"My duel with you was... quite fun! Please allow me to duel you again!"
Max Energy Deck (Japanese: MAXエナジーデッキ) is the only deck played by Nikki. She will battle a 6 prize card battle when challenged. Defeating Nikki gets the player two Island of Fossil booster packs.
At the beginning of the game, Nikki is not present at the Grass Club. Players must dual with and defeat Brittany in order to cause Nikki to appear at Mr. Ishihara's House. When found here, Nikki gives the player the Be Gone! GR2 Deck and the Oddish Coin. She will return to the club after GR-2 is defeated, but will only battle the player after the GR Coin is completed.
