Best is detail-oriented, more grounded yet often stressed, typically by the antics of his twin sister Bester. He is polite, yet sometimes quick to judge certain behaviour that may be seen as unnecessary or holding things up. However, he still enjoys the company of his sister, and the rest of the Bettervale citizens.

Best’s default bodiless form is a light magenta, crown-like object. What he and Bester turn into in each episode of "Best & Bester" is what they stay as until each episode ends.
