Teresa is a minor character in Disney's Lilo & Stitch franchise. Alongside Elena and Yuki, she is among the students in Lilo Pelekai's halau hula (hula school) and a sycophantic part of Mertle Edmonds's posse. Oddly, despite being named in Lilo & Stitch: The Series, she is referred to as "Aleka" by her kumu (hula teacher) Moses Puloki in Lilo & Stitch 2: Stitch Has a Glitch.

She is of Hawaiian descent, like Lilo, and has long, dark brown, wavy hair. She typically wears purple clothing for her casual outfit, wearing a purple headband in her hair, a light purple v-neck t-shirt and dark purple shorts, as well as black sandals. She also appears to be the tallest girl in the posse.

Lilo & Stitch: The Series vaguely implies that she has an interest in technology, showing a drawing of hula-dancing robot in "Cannonball" and helping Mertle cheat using an Internet-connected laptop and wireless voice communication in "Spike".
