Personality and Characteristics
Chuchu is a kind and caring Pokémon, much like her Trainer. Chuchu cares greatly for Bayley and is often the only one of her teammates outside of her. Much like her Trainer, Chuchu doesn't enjoy fighting, and only does so when it's necessary, such as in order to protect her Trainer and her mate, Pikachu.

Upon meeting Edge's Pikachu, she instantly sparked a connection with him and has since become his mate. Chuchu also cares greatly for her son, Pichu, and goes to great lenghts to keep him safe, and despite being rather saddened to do so, decides to leave Pichu in the care of Miguel after Pichu gained an immediate connection with the Trainer upon hatching.
