"Booster Gold", created by Dan Jurgens, debuted in DC Comics' "Booster Gold" #1 (February 1986), initially depicted as glory-seeking 'showboat' from the future, using knowledge of historical events and futuristic technology to stage high-publicity heroics. 'Booster' develops over the course of his publication history and through personal tragedies, evolves into a true hero weighed down by the reputation he has created for himself :
"...'Michael Jon Carter' was born poor in the 'Gotham City' of the 25th century, speaking 'Esperanto' as his first language. He and his twin sister 'Michelle' never knew their father because he left after gambling away all their money. Luckily for Michael, he was a gifted athlete and he managed to get into 'Gotham University' on a football scholarship.
"In college, nicknamed 'Booster', Carter became a star quarterback with a bright future. His father then reentered his life and convinced him to bet on games and then throw them. He was exposed and his once bright future shattered.
"He took a job as a night watchman at the 'Metropolis Space Museum', where he began to study displays about superheroes and villains from the past, particularly the 20th century.
"With the help of a security robot named 'Skeets', Carter stole devices from the museum displays, including a 'Legion of Super-Heroes' flight ring and a force field belt used by 'Brainiac 5'. Using a time machine, also on display in the museum, previously owned by 'Rip Hunter', Carter travels to the 20th century, intent on becoming a superhero and forming a corporation based around himself to make a comfortable living..."
