He is the son of Alan Scott and Rose Canton and the twin brother of Jade. According to an Infinity, Inc. letter page, Obsidian was named "Todd" after a friend of Thomas. Obsidian made his first live-action appearance on the second season of the DC show Legends of Tomorrow, with a younger version of the character portrayed by Dan Payne, with no speaking lines, and an older version portrayed by Lance Henriksen. Rice also appears in the third season of Stargirl on The CW network played by Tim Gabriel. Fictional character biography Obsidian is the codename of Todd Rice, who is the biological son of Alan Scott and Rose Canton, respectively the Golden Age superhero Green Lantern and villain Thorn. Todd was raised in an abusive adoptive home in Milwaukee, Wisconsin. He finds out in his late teens that he has a twin sister, Jennie-Lynn Hayden, alias Jade. The two meet, discover they both have superpowers and decide to follow in Alan Scott's footsteps and become heroes. The duo begin to operate under the assumption that Scott is their father. Although not certain of this lineage at first, the two eventually learn for certain that they are indeed Green Lantern's children. As Obsidian and Jade, the two were founding members of the superhero team Infinity, Inc., a group composed mainly of the children, grandchildren and protégés of members of the Justice Society of America. Post-Crisis (1987–2011) Obsidian also serves with the Justice League in their satilite-based space station headquarters. Obsidian has many various adventures at the headquarters, including helping the League deal with dozens of aliens who are the last surviving members of their species. During his tenure with the League, Rice undergoes therapy and also has to deal with seemingly permanent injuries to his shadow form. Obsidian apparently inherited a potential for mental illness from his mother, Thorn. Corrupted by Ian Karkull, Obsidian turned evil, using his shadow powers to first steal all the shadows from an entire city before spreading darkness over the entire world. During this time as a villain Rice attacks his foster father. Ultimately, his biological father Alan Scott, fighting as Green Lantern and with the aid of other JSA members, defeats him. Obsidian
