Luz the Supergirl
is a The Owl House and The DCU crossover, where Luz is the daughter of none other than Superman, and gets dragged to the Boiling Isles while on the way to visit her father.
- Adaptational Badass: Luz, being half Kryptonian, with the full set of abilities that her father's heritage gives, is a lot tougher than she was at the start of canon.
- Fusion Fic: This story combines Luz's Earth with the DC Universe, Luz herself being Superman's daughter.
- Living Battery: Darkseid brought Luz to the Isles to serve as a living power source for the rebuilt portal.
- Not Me This Time: Lex is obviously the main suspect when Luz disappears, but he's completely innocent this time.
- Villain Team-Up: Belos and Darkseid have made a deal with each other; Darkseid gets the Demon Realm as his newest conquest, and in exchange Darkseid helps Belos wipe out all the magical beings on Earth.
- What If?: The core concept is that Luz's Earth is the DCU, and that Luz is the half-Kryptonian daughter of Superman. Several things change as a result.
- Eda destroyed the portal at some point before Luz came to the Isles, with Belos getting the remnants earlier.
- Luz coming to the Isles was part of a plot by Belos and Darkseid,
