Mertle Edmonds is Lilo's rival and a recurring antagonist in the Lilo & Stitch franchise. She has been voiced by Miranda Paige Walls and Liliana Mumy.
Personality
Mertle is an incredibly spoiled little girl. She is the leader of a clique of girls who follow her every command. She has a strong disliking towards Lilo and refers to her as "Weirdlo" for most of the franchise. She is shown to be unforgiving and holds grudges against people, even when they apologize, as shown when Lilo apologizes for tackling and biting her earlier, she does not forgive her and only says rudely "Apology not accepted." It's shown in the TV series that her "friends" aren't too fond of Mertle's mean and bossy attitude, implying that, despite the fact that they hang out with her, they don't actually like her. Mertle takes great pleasure in putting down, insulting, bullying and making fun of Lilo.
Appearances
Lilo & Stitch
Mertle is a young girl attending the local hula class alongside Lilo, Elena, Teresa and Yuki. She gets into a fight with Lilo during one of their practices. After Lilo adopts a "dog" named Stitch, Lilo introduces her pet to Mertle, Elena, Teresa and Yuki. However, Mertle openly expresses her disliking toward the creature, calling it "the ugliest thing she has ever saw."
Lilo & Stitch 2: Stitch Has a Glitch
In the official sequel, Mertle serves as the main antagonist. She enters a hula competition against Lilo, which prompts the latter to practice really hard, ignoring Stitch and putting a strain on their friendship.
Stitch! The Movie
Mertle is a minor character in the film, appearing back and forth throughout the picture.
Lilo & Stitch: The Series
She became a recurring character in Lilo & Stitch: The Series. Throughout the series, it is established that she is from a relatively wealthy family and is a spoiled brat who lives with her mother. In one of the episodes, it is revealed that she keeps Gigi (Experiment 007) as a pet, but does not realize she is an experiment. Mertle is also associated with Hämsterviel.
In the episode "Finder", she mistakes Dr. Hämsterviel for a gerbil and keeps him as a pet for a short time.
In "Shush", when her friends break up with her after Lilo wrongly thought she hated them, she teams up with Dr. Hämsterviel, who apparently turns her into an android in order to catch all the other experiments in place of Gantu. However, she was rescued by Lilo and Stitch, who took her to Jumba to de-robot her. Lilo tries to be friends with Mertle in several episodes, but this usually just results in even more social rejection.
She is rejected by her friends in "Tank" and teams up with Stitch to capture the experiment. They fail and are captured but manage to escape in Stitch's dune buggy while Gantu gets the experiment. She initially tries to tell her friends about it, but stops and becomes friends with them again.
Leroy & Stitch
In the final film, Hämsterviel plotted to rule the galaxy using an army of Stitch clones named Leroy. He orders Leroy to kidnap all 623 experiments, including Gigi. When Gigi was captured, Mertle was taken as well. At the final battle, Mertle ran in fear while Stitch and his cousins battled the Leroys. In the end, Mertle and Gigi joined Lilo and her ohana in a huge family picture.
Comics
A few comics for "Lilo & Stitch" were released before the movie. The very first "Lilo" comic featured Mertle, but she was named "Jenny."
