Ashley is a serious, easily angered person. Ashley also seems to have a large ego (as stated in her theme song), and is prone to bouts of laziness; on one of the WarioWare: Smooth Moves secret boards, Red is said to take care of his and Ashley's laundry, and she orders Red to write her blog entry for her on the Japanese Smooth Moves website, although it may be out of shyness. Ashley is portrayed as shy and distant; both Touched! and Game & Wario show her not dancing with the other WarioWare employees (including Red) at the end-of-game party and her response to comments made by her coworkers on her blog entry is simply "Everyone... I hate you." Her resentment may be the result of her shyness and loneliness, however, since her theme song, her Game & Wario character card, and her trophy description all state she wants to have more friends. WarioWare Gold depicts Ashley opening up as she is shown playing cards with everyone else during the Potluck Gang stage, and her embarrassed blush in the stage's concluding cutscene hints she enjoyed her time with the others, and her "character trailer" published after the game's launch likewise shows Ashley visibly moved when other WarioWare employees invite her to trick and treat with them.

She has an annoyed, monotoned voice that brings emphasis to her angsty nature. But also sounds a bit shy in the process.
