Lambda Urban has long been dedicated to their studies in Dental Surgery but has always held an interest in the Universal Primate Captivity Crisis and has now become committed to a missionary in the Doctors' liberation efforts. Lambda was raised on a far rim colony on the New Frontier where they were eventually stationed at the Libertad Sector in a support role, where word of primates in captivity on Earth reached and spurred many into action. With their sights now set on Earth, Lambda and the Doctors will do what is needed to bring freedom to the wrongly imprisoned primates that remain.
