Big Malibu is an extraterrestrial half-blood.
From which system it comes it is not clear, she is the first to claim that she does not remember it, just as she does not remember from whom or how it was born.
Fortuitous circumstances, strange coincidences and her adventures have led her to know and ally herself with the Ancient Legio, with which she shares principles and morals.
She has often given herself to exploration up to Colonia and Sagittarius, but all her commitment is to become a valid pilot and to design and test her ships, constantly improving their potential.
