Star vs. the Forces of Evil Wiki

Mariposa Diaz is the baby sister of Marco Diaz and the second-born child of Rafael and Angie Diaz. She is first alluded to in "Marco Jr.", and she makes her first physical appearance in "Doop-Doop".


Mariposa is a female Latina-American infant with tan skin, short brown hair, and large hazel eyes. Like Marco, she has a mole on her right cheek. As a grown teenager in "Gone Baby Gone", Mariposa is of medium height and slightly stocky build, and she has thick eyebrows and very long hair. She is also seen wearing the finger puppet Marco had as a necklace.


Mariposa is first alluded to in "Marco Jr." when Angie becomes pregnant with her. Believing she is going to be born a male, Rafael and Angie preemptively name her "Marco Jr." after their firstborn son Marco.

Later, in "Doop-Doop", Star meets Mariposa for the first time when she goes back to Earth, and she is surprised that Marco's baby sibling was born a girl instead of a boy.

In "Britta's Tacos", Marco babysits Mariposa while trying to eat 50 tacos to win a mystery prize at Britta's Tacos. She is repeatedly mistaken as Marco's daughter instead of his sister by several customers, Sensei Brantley, and Oskar Greason.

In "Beach Day", she appears at the beginning of the episode in the Diaz Household eating her first breakfast quiche while her father Rafael takes pictures of her with an instant camera.

In "Gone Baby Gone", Marco babysits both Mariposa and baby Meteora. When Hekapoo appears to give Marco a warning to stay away from Mewni, she accidentally leaves a portal open to her dimension, and Mariposa and Meteora wander through it. By the time Star and Marco realize this and catch up with them, they have grown into teenagers because of the time difference between Earth and Hekapoo's dimension.

Mariposa and Meteora drug Star and Marco to sleep and attempt to sacrifice them to a wish-granting demon in exchange for giving Mariposa magic powers. But Mariposa changes her mind when she realizes the demon plans to devour Star in order for him to give her Star's magic. Star, Marco, Mariposa, and Meteora team up to defeat the wish-granter, and Mariposa and Meteora agree to return to Earth when Star and Marco entice them with the offer of food, reverting them back to infants.
