Yuga's Quirk gives him the ability to fire sparkly lasers from his navel.
The lasers can range from short to long-ranged ones, with strong enough recoil to propel the user through the air at a high speed. The beams are powerful enough to destroy metal, and because of their brightness, the Quirk can also be used to illuminate dark paths or to act as a beacon, allowing others to locate Yuga's current position. Yuga can also control the width of his beams and is skilled enough at maneuvering them, to the point of being able to write perfectly on solid rock through extremely thin lasers.
Yuga's Hero Costume is capable of channeling the energy created by his navel, allowing it to be fired from other openings granted by the costume itself. Abnormally, because of a birth defect, Yuga's Navel Laser can involuntarily "leak out", which means that he is dependant of his Sparkle Belt for his Quirk to function properly. According to Yuga himself, he has been constantly wearing his Sparkle Belt since he was a child.
This Quirk can only be used for 1 second at a time, otherwise overusing Navel Laser will cause continuous damage to Yuga's stomach.
- Art of Seduction (据え膳 Suezen?): Yuga's basic move. He places his hands behind his head and fires a continuous, straight beam from his navel. This move is first used to destroy a robot during U.A.'s Entrance Exam.
- Navel Laser Buffet: Yuga fires successive beams not only from his navel, but also from his shoulders, which are equipped with beam openings just like his Sparkle Belt. As a result, this technique puts more strain on him than when he uses his Quirk normally.
- Like several other Quirks, Navel Laser has its own signature sound effect: "THOOM".
- Yuga's pose when using his Quirk may be a reference to Rudol von Stroheim, a character from JoJo's Bizarre Adventure, who fires a machine gun from his stomach in the same manner.
