Aseefa is a main character in Planet Sheen.
Aseefa is a Glimmorian, a humanoid alien creature with a ponytail. She's a warrior princess, a beast-master and Sheen's love interest. She's cute, quirky, tough, punky and really likes Sheen as well, but Sheen is too nervous to say that he likes her. Aseefa owns a pet Chocktow, which is the most feared and dangerous creature on Zeenu.
Aseefa seems to take Libby's place as Sheen's significant other, but her personailty is more like Betty's. For some reason, Sheen never brings up Libby or even thinks about her in the series (or any of his other friends for that matter).
