Trini is a kind, thoughtful and compassionate girl. She is also the second most mathematical and scientific of the original Rangers, next to Billy Cranston. She alone was able to understand Billy's technical jargon early on, and loved to assist Billy in the creation of many of his devices. Trini also cared greatly about the environment, but Trini does not have many fears, but fear of heights is one of them. Trini only fights if provoked. Like her fellow rangers her true identity must be secret.
