The Lumas are one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the Super Mario franchise.
Lumas are star-like creatures that appear in Super Mario Galaxy. They are Rosalina's adoptive children and unlike most Stars, they have a tear drop-like shape, and come in many colors. They are much like Power Stars, but they are more circular in shape and able to talk. Lumas boast the ability to transform, from minor objects to entire planets and galaxies. Most of them make their home in the Comet Observatory, and others make their home with Lubba on Starship Mario.
Grand Interdimensional War
During Fate of the Multiverse, Grand Emperor Enoch orders his son, Eron, to kill a yellow Luma. Rosalina came to the defense of the Luma and took out her wand in protest. However, when she was about to use her magic, Enoch deflected her magic back and forced her to watch her child die at the hands of his son. As Eron is about to kill the Luma, he experiences a vision upon looking into it's eyes; unconditional love, the heart of the child. It is enough to break the Dark Spark's hold over him. From that moment on, Eron rejects his father's legacy and heritage as his son, bravely standing up to her father alongside his sister.
