Callisto "Cal" Langford is the son of legendary power rangers Andros Langford and Ashley Hammond. He was raised on KO-35 by his parents. Cal came to Earth to go to school, and he got an internship with SPD to further his ambitions of studying the Morphin Grid. He eventually became the white ranger. Particularly, he is close to Bridge Carson due to them both being aliens on a team of Earthlings.
