He has a short-lived, troubled relationship with Marcie Cooper, the third Harlequin, shortly before the disbanding of Infinity, Inc. Later, sexual confusion was shown during his tenure in the Justice League, when he told his friend Nuklon that the only two people he could ever love in the world were his sister and him. When Nuklon asked if he was gay, Obsidian did not fully answer, instead asking "Why must there be labels?" After Obsidian's redemption, "JSA" penciller Steven Sadowski stated that Todd's sexuality would be dealt with whenever he returned to that title.
