When he was first introduced, the hero known as Booster Gold was kind of a putz. A time-traveler from the 25th century, Booster relocated to our era to use futuristic technology to fight crime and get famous. Naturally, his headline-hogging attitude didn't endear him to many other heroes. After the events of Countdown To Infinite Crisis, Booster finds his edge. He returns to the 25th century and redoubles his efforts, coming back to our time with a new attitude that helps him save the Multiverse from the maleficent Mr. Mind.
