Watt is a female partner in Paper Mario. She was captured by the Big Lantern Ghost in Shy Guy's Toy Box and you had to set her free by attacking the lamp. She will give you a big thanks and she gets excited once she finds out that you're Mario. She then joins you. Her power is electricity. If you use her power in the field, she will light up dark areas and reveal hidden objects. She is the recommended partner for the boss battle against General Guy. She also has a mother who is very worried about her.
