A very energetic character born in Texas mere hours before Super Mario Sunshine was due to be released. Secretii Rules state that a Secretii has to be at least 20 years old to design a secret level, so Chuck had to be rapidly aged from an infant to the mentioned 20 years of age. She also had to make up a level on the spot so that Super Mario Sunshine can be released successfully. Many lives were lost on that level, and most of the blame was on Chuck's high energeticness.
Chuck has Peak Human Strength. This is fitting, as per her secret level.
Chuck is the heaviest Secretii. (and out of everyone in the Human Sunshine Project)
Chuck could arguably have the shortest hair in the Human Sunshine Project (her competitor is Blaine Cole). This could extend to Chuck having the shortest hair out of all of the Secretiis.
Chuck's gender can be very confusing, as the Secretii Rules state that Chuck has to be female.
