Sue is described as a "jock" by Blythe. Indeed, she does seem to have a knack for sports. She also has shown to be passionate and a little easy to frustrate sometimes. She seems to take things more seriously than others would as shown when Blythe temporarily befriended the Biskit Twins.
She also appears to idolize Blythe, as shown when she tried to emulate her in "Russell Up Some Fun."
