Butterfree (Greta Parker)

Caterpie is the first Pokémon Greta Parker caught in Pocket Monsters. Before Caterpie was caught, she used to live in Pallet Jungle.

Kanto Journey - The Beginning
After Greta was given a task to catch a wild Pokémon in Pallet Jungle by Professor Oak in, she visited the jungle with Redwald Walker. After she and her Nidoran battled a wild Spearow in the jungle, they encountered the Caterpie on a tree, eating leaves. Greta stated that she always dreamed of catching a Caterpie, which led them to have a Pokémon Battle. Caterpie's opponent was Nidoran. During their battle, Caterpie showed how good she was at climbing and walking on upright objects such as trees and walls. Also Caterpie would use her String Shot as a defense mechanism to slow down the foe and attack them with Tackle fastly. The Pokémon Battle were almost in a draw for the whole time until Nidoran's Poison Point was activated and Caterpie got poisoned for touching her. Eventually, Greta caught Caterpie and so she became the member of her team.

Caterpie appeared for the first time in after she was caught. While Greta, and  were in danger, she was called out of the PokéBall. She had been domestic and loyal to Greta. When her owner ordered Caterpie to use String Shot move, in order to slow down a wild Kangaskhan who was chasing them behind in Pallet Jungle, Caterpie did her best to stop her for a while.
