COMIC BOOK BIO BY DC DATABASE
Little is known thus far about Obsidian of Earth-2 save that he is a member of the Justice Society of America and that he is searching for two of his missing allies, Superman and Power Girl. The Earth-2 Obsidian bears a strong likeness to his New Earth counterpart Todd Rice, who was originally indigenous to Earth-Two prior to the collapse of the first Multiverse during the Crisis on Infinite Earths event.
