Among the Young Six, Yona is portrayed as very excitable and clumsy, initially frequently tripping over her own hair. Like most yaks, she speaks in broken English and in the third person. She harbors a lot of pride and love for her home of Yakyakistan, repeatedly proclaiming everything yak-related to be "best" and wanting to share that with the other creatures of Equestria. Her pride for her heritage at the expense of other creatures is somewhat conceited at first, but after getting to know some of her fellow students, her jabs at other creatures become more playful. In What Lies Beneath, it is revealed that Yona suffers from arachnophobia, a fear of spiders, but she overcomes it with the help of a spider named Spindle. In She's All Yak, Yona becomes self-conscious about fitting in among pony society, wanting to be the "best pony pal" for Sandbar.
