Star Butterfly (Adopted Mother)

Nia Butterfly (Adopted Sister)

**Asterossa** "**Astro" Tartarus Butterfly** is the adopted son of Star Butterfly, and older brother of Nia Butterfly. He is the biological son of Typhon and Rosetta Butterfly, and is the Captain of the Queensguard.

## Background

Astro was born to Typhon and Rosetta Butterfly. His father, being an former enemy of the Magical High Commission, worried for his safety and decided Rosetta should take him to Earth to hide until he was able to free himself and join them. After being discovered the Commission came to take him, which resulted in the death of Rosetta. Afterwards he was taken in by Star and raised as her son.

Feared as a threat by the Commission, and doubted by the citizens of Mewni, he strove to prove himself to them. At the age of twelve, he started training to become a knight, and he quickly rose through the ranks. By the time he was fourteen, he had become captain of the Queensguard. He became the pride of the Butterfly kingdom, and everyone grew to see him as a hero.

Eventually, he travels to Earth, mostly to protect his sister Nia, and despite his best efforts he ends up getting involved in the battle between the Young Blood Alliance and the Vanguard League. Because of one of his friends Vera, and because the YBA was responsible for two attacks on his sister, he ends up siding with the Vanguard, joining the Super Natural Department.

## Personality

Astro comes off as a rather stiff and stern type of person to most. He takes his title as a prince very serious and does his best to set a good example for his sister and his people. He's completely dedicated to protecting his sister and defending the kingdom of Mewni. To the people of Mewni, he's seen as a legend, a perfect prince whose kind and untouchable in battle. A champion of Mewmans and Monsters alike. But he's honestly afraid of not living up to these expectations and everyone's judgement about his father.

Astro enjoys relaxing things like gardening, drinking tea, and playing music (he can play pretty much any stringed instrument). He also likes taking his Dragon-cycle (Sear) out for rides, and training on his spare time. He has also began taking an interest in video games. He has a massive sweet tooth and a soft spot for small animals. Despite his stern attitude, he usually ends up caving when it comes to the women in his life (his Mother, Nia, Vera, etc...) He's very polite and he usually ends up bowing to people a lot (it's become sort of a habit now). Though he also has a love for fighting, he doesn't like to show it since he sees it as unbecoming of a prince.

In a fight, especially in his monster form, he becomes far more arrogant (though not careless). He is very protective of his friends and family, and will not hesitate to put himself in danger to protect them. He is especially protective of Star and Nia, and tends to grow far more violent when either is threatened.

## Appearance

Astro is a tall boy with light skin, teal combed back hair, mauve eyes, and purple skulls on his cheeks. He wears a sleeveless purple hoodie over a black t-shirt, blue jeans, a belt with a skull buckle on it, and a pair of white and purple tennis shoes. He carries his sword at his side in the form of a snowflake shaped key-chain.

After going off to train with his father, his hoodie gets destroyed and his horns can no longer go back into his head. He also starts wearing a pair of finger-less gloves.

In his monster form, he grows more of his father's traits. The whites of his eyes turn black, he grows curved horns and a long pointed whip like tail, his teeth turn razor sharp.

## Relationships

### Family

He is very close to his mother, seeing her as the (mostly) perfect example of a queen. She tries to teach him how to lighten up and relax, and while he tries he feels like he still has to act royally, which sometimes drives Star crazy. But overall they are very close and love each other. Moon is like a mentor to him. He learned all about how to act like royalty from her. He looks up to her and will often to go her for advice. They both usually end up nagging Nia about behaving like a princess. River is a father figure to him, and he tends to act a bit more relaxed and playfully around him. They wrestle often, though he tends to hold back since he doesn't want to hurt the aging fellow.

### Nia Butterfly

Astro has always been protective of Nia. He made a vow when he was young to always protect her and he's hellbent on keeping it. This does lead to him being overprotective at times. Around her, he acts much more like a big brother and is less concerned with coming off as a flawless prince. He admires how easily she'd able to get along with others, and is incredibly proud that she looks up to him.

### Typhon

Typhon is Astro's biological father and a former member of the Magical High Commission. He originally thought he was responsible for his birth mother's death, and aimed to kill him out of revenge. But after discovering the truth the two have aimed to reconnect as father and son. He regularly visits and trains with Typhon, who teaches him to fight "more like a monster".

### Maria Kelpbottom

Maria is the princess of the Waterfolk kingdom and Astro's girlfriend. He genuinely feels she's too good for him and constantly puts her on a pedestal. He cares for her deeply and for the most part the two are always on the same page. However when Maria is angered she won't hesitate to let him know. They're both pretty shy about PDA.

### Vera Lucitor

When he was younger he was jealous that Vera seemed to be loved by all so easily, and also that she didn't have to hide who she was. He does appreciate how protective she is of Nia however, and because she means so much to his sister and Maria, he will protect her just a fiercely as any of his other friends. Since getting over his jealously of her he views her as a close friend.

### Micah Jojo

Astro considers Micah to be his best friend and trust him a great deal. Micah is one of the few people on Earth, to get Astro to lighten up and relax showing him that he's more than just prince, he's a kid just like him. Micah also got him into gaming, regularly beating him and driving the prince to practice and try and return the favor.

### Amber

Though originally distrusting of Amber because of her father's attacks on his family, and way her mother treated him as a child, he has grown to respect her as a warrior, and trust her as an ally. The two have grown somewhat close over time, and get along rather well now.

### The Calamities

Astro is the leader of the Calamities, and has known them for some time. He grew up with Breeze and while the two initially didn't get along very well, they grew a healthy respect for one another over time. As his lieutenant he trust her a great deal to lead in his absence. Fum was his former squire and looked up to him immensely. He shares a brotherly bond with him and wants to groom him to lead the guard someday. Slick often annoys him with his reckless behavior, and always wanting to egg him into a fight. Though he does enjoy their fights against one another and occasionally will get swept up into his more reckless ways.

### Hody Kelpbottom

Hody would constantly mock and insult him every chance he got when they were younger, constantly reminding him that he was a bastard, and this has led to a deep dislike and rivalry between the two. Astro honestly can't stand him, and only tolerates as much as he does because of Maria.

### Magical High Commission

From the second they knew he was born, the Magical High Commission feared that he would be a major threat to the kingdom like his father. While they couldn't do anything to harm him under Star's protection, they made efforts to try and limit his training in magic and combat every chance they got. Astro never cared for them, and after finding out about Rosetta he absolutely despises them. He tolerates them when doing his royal duties, but otherwise wants nothing to do with them.

## Powers and Abilities

### **Abilities**

**Biology**: Due to his monster heritage he is considerably strong and durable. He also seems to have an instinct for combat, and when in his monster form is far more agile and light on his feet. He is endurance is astounding, and he is able to keep fighting even through injuries that would prove fatal to most.

**Swordsmanship**: Astro was taught swordsmanship by both Queen Margo and Higgs the Swift, and is incredibly skilled at it. He is widely regarded as Mewni's greatest swordsmen, but will deny this, insisting the title still belongs to them.

**Water**/**Ice Magic**: He has a wide variety of water and ice based spells. Though he typically relies on brute strength and close combat, he uses this for mid to long range combat.

**Fire Magic**: His fire magic is slightly stronger than his ice based magic, but he has a far harder time controlling it which is why he usually avoids it. In his monster form he has a bit more of a handle on it.

**Dark Magic**: He was tutored by Eclipsa and studied his mother's old books to use dark magic. Because of his biology he is able to use it without the backlash that typically comes with it.

**Monster Abilities:** He is able to absorb magic or energy based attacks and fire it back through his horns, and create portals on his own. Though he very much struggles with this since their rather new abilities. He also seemed to have his father's ability to intimidate other monsters, though this usually only happens when he's angry.

### **Weaknesses**

While Astro is incredibly strong and durable, he isn't particularly fast, and is forced to rely on minimal movements to make up for it. He has a particularly hard time dealing with fast or quick opponents. When in his monster form for too long he tends to act more recklessly and aggressively, thinking far less clearly and strategically.
