*“You wear a helmet in the gym shower one time and you're labeled for life!”*

―Marco's rant about his safe kid monitor

**King Marco Ubaldo Diaz** (born November 28, 1980[32]), is the titular deuteragonist of Aurora: The Princess of Another Dimension franchise. He is the son of Rafael and Angie Diaz, as well as Star Butterfly's best friend on Earth and an adult king of the Kingdom of Mewni/Earth (located in another dimension).

In a theme song, Marco and his best friend Star Butterfly sent his daughter and Sam to Animal village (main characters in *Star vs. the Forces of Evil*) after an attack on his daughter's life.

## Background

### Personality

Marco is practically the exact opposite of Star. He is very wary and tries to avoid any trouble or exposure. Because of Marco's cautiousness (and the one time he wore a helmet in the gym shower), he is labeled by both his peers and school staff as the "safe kid". Ironically, despite his predilection toward practical caution, Marco seems to enjoy the prospect of combat and adventure (In the pilot episode, he even expressed a desire for "some action and danger in (his) life"). Marco also seems to want this to be opined so with his reputation, as well; Marco openly expresses disdain for being considered a "Safe Kid", and has repeatedly attempted (to little avail) to persuade others to view him as otherwise.

Marco has proven to be notably irritable, as seen in his rambling about his reputation in the pilot episode, and his very quickly losing patience with Star in the same episode. He has also demonstrated poor sportsmanship, elevating himself and slandering his opponents in the Arcade Dimension of the episode immediately following, though this may have simply been on account of his anger and defensiveness against Pony Head, due to her mistreatment and threats against him.

Marco seems to have studied martial arts extensively, namely Karate, as seen in the pilot episode, in which he employs it to combat the monsters who come to assassinate Star (even explaining it as such to her). He can also briefly be seen in the introductory animated sequence about to break a wooden board, a common test of strength and technique in East-Asian martial arts.

### Appearance

Marco is a medium-sized adult with a slender build, tan skin, dark brown hair and brown eyes. He also has a small mole on his right cheek.

#### His past in *Star vs. the Forces of Evil*

As a a fourteen or fifteen-year-old teenager, he is typically shown wearing a light gray shirt, a red hoodie jacket, dark gray jeans, and an olive-and-white pair of sneakers. In episodes like "Sleepover", he wears a turquoise vest instead of his red jacket.

## Appearances

### Aurora: The Princess of Another Dimension

5 years ago, a 19 years old Star Butterfly and Marco Diaz married after the dimensions of Earth and Mewni have been "cleaved" together (since following from the previous episode, Cleaved). Later in 7 years, He is first seen by Star's sickbed while she is heavily pregnant with their daughter, Princess Aurora Angeline Butterfly, and lighting the lantern with Star later on after Aurora's birth.

11 years later, Aurora inherits the ring of Star Butterfly and Marco Diaz for Aurora's 14th birthday.
