Superpoder directly translates to "superpower." It's an engaging and somewhat playful word that immediately brings to mind comic book heroes and extraordinary abilities.
In the song, Paulo Londra asks, "Si esta noche vas a mostrarme tu superpoder" (If tonight you're going to show me your superpower). He uses this word metaphorically to refer to the unique and captivating qualities of the woman he's singing about, hinting at her special charm and allure in a romantic context. It's a fun and memorable way to describe someone's exceptional qualities.
Paulo Londra opens with a simple compliment and means it literally. "Mujer maravilla, eres tan sencilla" ("Wonder woman, you're so simple"), he sings, "que ni te maquillas, pero siempre brillas" ("that you don't even wear makeup, but you always shine"). She's a superhero to him, but the whole joke of the title is how little effort it takes her.
From there it turns into a straight invitation. He's got a room booked ("Tengo la suite del hotel, no la dejemos perder," "I have the hotel suite, let's not let it go to waste") and keeps circling back to the same question, three separate times in the song: "Si te llamé, bebé, es porque yo quería saber, si esta noche vas a mostrarme tu superpoder" ("If I called you, babe, it's because I wanted to know, if tonight you're going to show me your superpower"). One line even switches languages entirely, "Tu mirada es fría como winter fall" ("Your gaze is cold like winter fall"), which is a strange thing to say to someone you're trying to flatter. It closes the way a lot of reggaeton tracks do, on a nonsense chant instead of a real verse: "Ba-ra-ra-ra, ba-ra-ra-ra-pa-pa."
