Booster Gold was the first major new character to appear in The DCU after Crisis on Infinite Earths. He first appeared in "Booster Gold" #1 (February, 1986), created by Dan Jurgens. Born in the 25th century, Booster Gold, born Michael Jon Carter, was a famous college football player, until he got caught betting on his games. After that, his life was a wreck: he was disowned from his family, expelled from college and he couldn't play football anymore. It wasn't until he got a job at the Metropolis Space Museum as a security guard that he got the idea to go back in time to become a superhero and make a little money at it too. So he stole the Time Sphere and brought along Skeets, a security droid that he had befriended.Originally intending to call himself Goldstar, at his first public appearance he flubbed it, combining his football nickname Booster with his intended superhero name. Booster then went on to be a part of the Justice League International, where he met and befriended Ted Kord, the second Blue Beetle.Was the star of his own series once again, from October 2007 to August 2011, in which he roamed the timestream protecting history from enemies who — if they ever saw past his foolish reputation and realized he was the one foiling their schemes — would not only kill him but do it in such a way that Booster Gold never existed. So now instead of promoting himself, Booster had to do everything in his power to make people think he was an inept idiot, in order to carry out his mission to defend time itself. However, with the New 52 relaunch on the rise, this series — along with a number of others — was canceled. Booster was in the New 52's Justice League International series, though that has also been canceled with #12.Also frequently appearing in Batman: The Brave and the Bold.And for the last time, he's not the Green Lantern.
Tropes that can be found in Booster Gold:
Aborted Arc: At the beginning of Volume 1, Trixie Williams was being developed to being Booster Gold's love interest; then, wthout explanation, after the 25th century story arc, she was abruptly shipped with Dirk Davis. Again, in the last issue of Booster Gold Vol. 1 (and after Dirk Davis was inexplicably revealed to be a villain), Booster confess his love to her, the two kissed and... he flies away. The two will share a few panel in the subsequent decades.
Back from the Dead: Michelle, Booster's sister. This happened to Booster himself back in the JLI, he died on the operating table but because of the situation, was (effectively) a zombie for about a day. Then Ted built him a Power Armor suit that would double as life support.
Blue Oni Red Oni: Booster (Red Oni) and Michelle (Blue Oni) have a bit of this trope.
Break Out the Museum Piece: Though the point of going to the 20th century is that these 25th century "museum pieces" are still incredibly advanced tech by our standards. Though the flight ring and force field belt are actually future tech, they were e left behind in "modern" times by Brainiac 5 who originates in the 30th/31st centuries depending on the continuity.
Butterfly of Doom: Features in the various time travel plots. Such as Max Lord taking over the world because Ted lived.
Character Development: Booster's increasing popularity is largely the result of enormous amounts of character development following Ted Kord's death. A good measure of how far he's come? 1980s JLI had Booster as largely ineffectual comic relief. 2010's JLI has Booster quickly asserting himself as the natural leader.
Chest Insignia: Both Booster and Goldstar share a simple blue 5 pointed star.
Civvie Spandex: When Booster saves Cyrus's life at the end of the story, he adds a longcoat to his uniform.
Crouching Moron, Hidden Badass: The series revolves around this trope. Back in the day, Booster was a shameless glory hound (though his heart was in the right place) with a reputation for screwing up. Now, he's just the opposite: he's developed into a truly great hero, but his mission depends on convincing the world that he's still just an egocentric dope.
Daydream Believer: When Booster suggests they make a pit stop in the 1950's, Rip answers, "for the last time, The Fonz is a fictional character!" Booster replies that Rip is just being mean.
Evil Counterpart: Maxmillion to Skeets, the third Supernova for Booster. Maybe the Chronos Twins to Booster and Goldstar.
Fake Ultimate Hero: Or he would have been if anyone had taken his boasts seriously. An Inverted Trope after his character growth - he's a genuine hero whose effectiveness relies on almost everyone thinking he's still an attention whore.
Flanderization: Booster Gold started as a well-meaning hero whose love of money often got him in over his head. Over the course of the '80s and '90s, writers forgot about the "well-meaning" part and turned him into a money-grubbing jerk. Thankfully, over the course of Infinite Crisis and 52 in the mid-'00s, DC built Booster back up, and now he's a genuine hero again—though the lure of fame and fortune still occasionally tempt him. Even better, he now intentionally acts like that, so no-one except Batman and Superman realises that he's grown into a competent hero in his own right, whilst he roams the timestream protecting history from enemies who — if they ever saw past his foolish reputation and realized he was the one foiling their schemes — would not only kill him but do it in such a way that Booster Gold never existed. So now instead of promoting himself, Booster must do everything in his power to make people think he's an inept idiot, in order to carry out his mission to defend time itself. Even before 52, some writers had started pointing out that there was more to Booster Gold than met the eye. At one point one of the other heroes muses that, being from the future, Booster must have been aware that Doomsday was a monster that was fully capable of killing Superman. And he still stepped up and took the first actual punch Doomsday aimed at a hero on his personal forcefield, to protect another member of the League. Both this acknowledgment and the moment itself hint that some people never completely forgot that Booster was kind of badass.
The Greatest Story Never Told: Booster's Justice League Unlimited episode, the Trope Namer. Also part of Booster's current title, as he has to let history think he's an idiot in order to do what he does.
Green Eyes: One of the first things you notice about Sondra Crain.
Heroic BSOD: Booster, on learning that his only legacy will be the egotistical Peter Platinum. Michelle, when she finds out that she should have died.
Legacy Character: Goldstar; the first Goldstar was Trixie Collins. Blue Beetle — in fact it has all the Blue Beetles (including the futuristic Black Beetle) in one shot. Michelle and Trixie (as stated above). Booster becomes Supernova at one time, then gives it to Daniel Carter and in the future Booster's father even has the suit! Not to mention it's been hinted that Rip would take up the Booster Gold mantle at some point. So yeah.
Secret Keeper: Booster discovered that Batman had the photos of him trying to help Barbara Gordon when he tried to prevent The Killing Joke. When Batman acknowledged that Booster has a more important job to do, he became Booster's Secret Keeper.
Secret Legacy: Played with. Booster thinks that the only legacy that he's going to leave behind is the egotistical Peter Platinum. In actuality his legacy is that his family becomes the Time Masters. Also, in the Millennium event, it was revealed that Booster is a descendent of the Chosen and will aid in humanity's evolution; he still doesn't know about this.
Tarot Motifs: In Trinity, Booster makes an appearance in the Justice League Arcana as the 15th of the major arcana (the Devil, which represents over-attachment to material things - fitting for Booster).
Tears of Remorse: What sent Booster over the edge at Blue Beetle's funeral was his inability to speak.
Took a Level in Dumbass: Like most of the characters in Justice League International, he underwent a fair bit of Flanderization in the title. He started off as a fairly likable, competent hero in his own book, but got progressively stupider and more vain once he joined the Justice League. It's even Lampshaded in Formerly Known as the Justice League, where Blue Beetle points out that Booster used to be fairly intelligent, and accuses him of acting dumb and childish on purpose. Later on, it is confirmed to be (mostly) an act.
Would Hit a Girl: In Booster's first Justice League International appearance. He justifies this by saying that his future is one of gender equality, meaning that female villains get the same treatment as men.
You Can't Fight Fate: Downplayed. While it is possible to change some things in the past to affect the rest of the timeline, this can lead to a Butterfly Effect that can change everything; usually the only reason Booster can affect the past is because it has already been changed/is in danger of changing on it's own due to timeholes. The theorem of "solidified time" explains: some events in time become so important to future events that they cannot be changed or will happen regardless of inference. For instance, Booster can't save Barbara Gordon because if he did she wouldn't become Oracle, Blue Beetle still dies "officially" because then the events leading to Max Lord's death won't happen, which stops Infinite Crisis from occurring, which in turn means The Multiverse wouldn't exist.
