Elena, Teresa, and Yuki

Elena, Teresa and Yuki are three girls from the Lilo & Stitch franchise. They serve as Mertle's friends/minions and Lilo's rivals.

Personality
Not much is known about their personality because their character was not focused on a whole lot. They obviously enjoy the art of hula dancing, since they attend a hula class along with Mertle. While they are mostly mean towards Lilo and Stitch, they are also kind to them as well, usually when Mertle is not around at all, so it's hard to tell whether they are nice or mean hula girls.

Family and Relatives
At the the very end of the episode "Wishy-Washy", there is picture of each hula girl with her parents just to show what they look like, but this is about all that is known about them. Also in the episode "Finder", Yuki apparently has an uncle as well, when she remarks, "I wonder if he could find my uncle Jimbo."

History
They usually travel in a group with their leader Mertle, and seldom say anything other than a sarcastic "Yeah!" in unison when agreeing with whatever mean thing Mertle has just said about Lilo. It is often hinted that the three hula girls would probably actually like Lilo if Mertle didn't make them think that they didn't. They have even ditched Mertle to hang out with Lilo for a while, like in the episodes "Tank" and "Shush", and they seemed to have enjoyed their time with Lilo on both occasions up until going right back to Mertle in the end. Also in the episode "Mr. Stenchy", Elena says to Mertle, "Hey, there's Lilo! Should we invite her, too?", referring to one of their little tea parties at Mertle's house, and sounding as if she wouldn't mind having Lilo join them.

Trivia

 * In Lilo & Stitch 2: Stitch Has a Glitch, Moses calls Teresa "Aleka" for some reason.
