Starco

Starco is the het ship between Star Butterfly and Marco Diaz from the Star vs. the Forces of Evil fandom.

Canon
When Star was sent to Earth, Marco began her first friend. Even though he wasn't so sure about Star at first and didn't like the idea of her staying with him and his family, since Star's magic is "glitchy" and brought him trouble, until villains from Star's world gave him the exactment Marco longs for.

In "Here to Help," Star and Marco head down to a pig-goat shack to sort out every single. While doing so, Star, glad that they're alone together, brings up what Marco said in the Realm of Magic. Unbeknownst to him, he claimed he loves her, which he admits. In fact, he's been feeling this way since they first met, even before the whole Blood Moon Curse. This has gotten a lot stronger overtime, which Marco never said a word about, as he thought Star just wanted to be friends. Ultimately, they kissed, and Star admits she loves him back. With the whole thing cleared up, the two happy couples evacuated the pig-goats heading back to the castle.

Fanon
Starco is the main ship of the fandom and when it became canon in the final season it pleased fans to know that the show's two main heroes got together.
