Onie's first role was portraying four year old Harlow Moon in WeCrashed, playing opposite to her on-screen parents, Anne Hathaway and Jared Leto. In 2023, Black Flies was released in-competition at Cannes, in which Onie played Sylvie, who was the daughter of Sean Penn and Katherine Waterston's characters. And, since, she has had enormously joyful acting experiences and hopes for more to come! Also, Onie has her own YouTube Channel called "Onie-ing It with Onie"- a fun art show with songs and special guests!
