Lux Riege is a student and superhero who is the current holder of the Bull Miraculous. With his magical helix located on his ears, inhabited by a kwami named Elliot, he has the power of strength and can transform into the superhero Bruno.
Lux was born on U.S. soil to Australian Diplomat Elena Riege who was visiting at the time. Although he was unexpected (Elena didn't even know she was pregnant) Lux was born healthy. Elena treasured young Lux, taking him all around the world with her while he was homeschooled by his Nanny. Eventually Elena married a man named Michael Riege who treated Lux like his own son. Despite everything Lux was always fascinated by his Birth Place, America, and eventually left to live there. During his time around the world, Lux received his Miraculous in Morocco from an elderly woman.
Lux owns a lasso when in Bruno's form. Much like Ladybug and her yo-yo, he is able to purify with his lasso.
Elliot is Lux's Kwamii.
