Toge was bullied by Team Skull grunts during her first appearance. Gabe and her friends sent out Litta, Rowlet, and Rainy to protect Toge and Team Skull threatened to take Litta, Rowlet, and Rainy away along with Togedemaru. Erika told them that they're not taking anybody's Pokemon. The Pokemon fought and scared off Team Skull. A young boy with his own Togedemaru who was revealed to be female along with Toge helped heal Toge and Toge chose Gabe as her trainer.
Toge distrusted humans at first due to being abused by Team Skull and would cower in fear. But when she met Sophocles, Gabe and her friends, she warmed up to them. She decided to go with Gabe knowing she could trust her.
