Butterfree much like in PMD Rescue team Red and Blue has lost her baby catterpie and Milo and Riley offer her help to go into Tiny Woods and rescue her baby from the dangerous fissures that have opened up in Tiny Woods.  Later on in the chapter she offers Milo a place to stay in her tent as Milo has no where to go since he isn't from that world.  She even offers a few apples and berries to Milo and Riley on their travels to Mt Steel.  She is a very supportive character when it comes to helping those around her as she is very open to having conversations about certain topics.

Butterfree's personality she is a very caring and kind hearted pokemon that is very open to helping those around her.
