Larry Lance's original appearances pertained to being a civilian love interest for Dinah Drake (Black Canary's alter ego), a male "damsel in distress", and occasionally as a crime fighting partner and capable detective to Black Canary; a dynamic of equality similar to the relationships between Steve Trevor and Wonder Woman or Mera and Aquaman.
[1] In Justice League of America #73 (August 1969), Larry plays a larger role as he tends to Starman after the hero is wounded in a battle with a cosmic powered villain called Aquarius.
After a universe spanning battle in Justice League of America #74 Larry sacrifices himself to save his wife from a blast of cosmic energy directed at her by Aquarius.
This conversation happened at a society event which was interrupted by a serial killer later dubbed 'The Blonde Slasher', who left a victim for Larry and his wife to find.
In this new timeline, the Dinah Drake Black Canary is re-established as a singular heroine and is supposedly on the run from the law for the murder of her husband, Kurt Lance.
[5] Later, a member of Amanda Waller's task force known as Team 7 is revealed to be Kurt Lance, alive and well, working deep undercover.
