Outwardly, Glisten is a charismatic, prideful and outgoing Toon. He enjoys being the center of attention and being included by the other Toons, and is obsessed with appearing perfect in both his appearance and capabilities.

However, underneath his flamboyant persona, Glisten is rather insecure, as implied in many of his interactions, notably with Sprout, Toodles, Rodger and Astro, becoming defensive when they point out his shortcomings. He often overworks himself in maintaining his flawless facade, which is best showcased in 2 of the notes lying on the floor of his room in Roleplay Mode.
