Ferro Lad is a member of the Legion of Super-Heroes in the 30th Century. Born on Earth, he has a mutation that allows him to transform into living iron. His brother Douglas Nolan also shares this power. He died shortly into his tenure as a Legionnaire, sacrificing himself to stop a Sun-Eater and save the solar system. In Reboot Legion continuity, he is born in the 20th Century and uses the name Ferro. He meets the Legion while they're trapped in the past and fighting a Sun-Eater during The Final Night. This version survives the encounter. There is no counterpart to Ferro Lad in Prime Legion continuity. Ferro Lad was created by Jim Shooter, first appearing in Adventure Comics #346. (1966)
