Hero 1 is the former leader of the British-based hero group Dawn Patrol as well as the leader of the Omega Team that sacrificed their lives to put an end to the First Rikti Invasion of 2002. He is also the successor to legendary British superhero Hero One and inherited both his distinctive Union Jack cape and the famed sword Excalibur.
According to Lyon Powers, Hero 1 was secretly married to current Dawn Patrol leader Lady Jane at some point prior to him leading the Omega Team. Prior to leaving he also passed his sword on to Ms. Liberty to protect until a worthy successor would appear.
In honor of his sacrifice, Statesman ordered all heroes to surrender their capes for the first few years after the Invasion.
It is believed his spirit still inhabits his memorial in Atlas Park.
