Tierra

Tierra (Japanese: ナツキ Natsuki) is the character of the day in the anime who appeared in the episode Control Freak!. She is an archaeologist who was trying to find a secret chamber in which a magical mask having the power to control the minds of Pokémon was supposed to be placed. Ash, Misty, and Brock first met her when Brock's Golbat flew away while they were having a meal. Brock followed Golbat and he came across Tierra, lying unconscious. Brock, as always, immediately fell for her and helped her regain her senses. Tierra was then introduced to Ash and Misty. Later, the four managed to find out the magical mask Tierra was seeking, only for Jessie to steal it and use the power of the mask to control Brock's Geodude and Onix, Ash's Pikachu, and Misty's Togepi. Brock's Golbat managed to break through the power of the mask, but was attacked by Geodude and Onix and was buried under rubble. Brock risked his life to dig out Golbat because of this, it evolved into Crobat and blasted Team Rocket away. After that, Tierra kept the mask for further study and the group waved goodbye to her as they continued their journey to Olivine City.
