Golden Age Origin

Kalthar the Giant Man was chief of the Urgana tribe and protector of the jungle. He was adopted by the tribe after his father died to save the Urganas from Arab slave traders. The Urganas gave him the name Kalthar meaning “God-Son.” He learned to speak to animals and when he reached manhood, Kalthar was given a gift from the witch doctor, Talo. Kalthar is given red grains of growth which allow him to grow up to fifteen feet tall. The green grains return him to normal. Besides growth and animal communication, Kalthar also had some invulnerability as he survived both bullets and explosions. His enemies include Abdul the Arab, Queen Loha, Pierre LeBrun, Leopard Men, and the Hordes of Shem. Kalthar marries Kate Goodwill, the daughter of Professor Goodwill.
