Intergalactic warrior Star Butterfly arrives on Earth to live with the Diaz family. She continues to battle villains throughout the universe and high school, mainly to protect her extremely powerful wand, an object that still confuses her.

As tradition dictates, Star receives the royal magic wand for her 14th birthday, but her parents worry that she is not ready for the responsibility and send her to a place they deem safe - Earth.

Star's best friend from her home dimension pays a visit and feels threatened by Star's new friendship with Marco.

Star fails her first test, so she tries to play match maker for their classroom teacher to get a better grade. However, she winds up turning her into a troll.

While Marco is distracted by protecting his friend, the new school mascot, from being kidnapped by their football rivals, a confused Star believes this to be an upcoming battlefield and starts making plans of her own.

Marco breaks his arm before a Karate tournament. Star uses her wand to fix it, but accidentally gives him an evil sentient tentacle arm.

Star vies for attention with a foreign exchange student who is visiting the Diaz family.

Star is feeling down when her crush Oskar has no calls from her, so Marco tries to cheer her up only that he accidentally summons Ludo and his army of monsters.

Star and Marco must go to "Quest Buy", a maze-like store to find a charger for Star's wand.

Star takes the Diaz family out vacation to her home dimension of Mewni.

Star doesn't get invited to Brittany's birthday party and is desperate to get into it.
