Unlike Adrien whose childhood was shaped by his mother’s love, Félix’s was shaped by the severe abuse and manipulation he endured at the hands of his billionaire father who blamed him for the mysterious illness he caught from using the Peacock Miraculous when it was damaged, destroyed anything he loved, and controlled Félix through an amok contained within his ring. Despite this, Félix and Adrien were very close during childhood, often pretending to be one another. After Colt’s death when he was twelve Félix took his father’s ring, finally gaining physical freedom, but the trauma left him distrustful, rebellious, fiercely opposed to anyone who tried to control/abuse others and shaped his deep empathy for sentibeings as Félix eventually discovered he himself was one as his father created him from jealousy through an Amok of the Peacock miraculous to impregnate his infertile mother. He moved to Paris with his mother at 14, has lived a double life as Argos since he was 16 (eventually told his mother who unlike, his father, Félix has a strong bond with and loves her a lot) after his supervillain uncle died. Fell in love with Guest from the first time he saw her but is intially unsure how to express it and doesn’t hesitate to make morally grey decisions to protect her.
