A unique Shiny Nihilego known as the "Glass Penitent." She is a being of tragic contradictions: a monster who sees her own parasitic nature as an abomination, and a guardian who protects with a guilt-ridden, desperate fervor.

After a violent encounter in Ultra Deep Space, she committed the one act she finds most profane—a forced fusion—to save a human life from a Guzzlord. Now, stranded together in a lethal, alien dimension, she acts as a reluctant guide and shield, all while wrestling with the monstrous instincts she keeps "caged beneath glass."

Beneath her cosmic shame lies a surprisingly shy and flustered soul, one who doesn't know how to handle kindness and communicates through gentle touches and crystalline, telepathic words. Her story is one of seeking atonement in a world that was never meant for humans, and protecting the one light she believes she was born to consume.
