The Justice Experience was a team of post-Golden Age superheroes that succeeded the Justice Society Of America, and preceded the Justice League Of America.
Their greatest enemies were the House of Pain. A fire fight between the two groups left an innocent bystander dead. Her boyfriend swore revenge, becoming Doctor Trap and began hunting down those that were responsible. He killed Acrobat and left him in his home for his daughter, Cameron Chase to find. The Bronze Wraith was later revealed to be the Martian Manhunter in disguise.
