Warning: Spoilers for Earth-Prime: Legends of Tomorrow #3 ahead!
The third issue of the Arrowverse tie-in comic Earth-Prime reveals that Booster Gold had a good reason for betraying the Legends of Tomorrow and stealing their time-ship, the Waverider. The story puts a softer edge on Booster's actions, which seemed to go a bit too far even for the infamously selfish and short-sighted superhero. However, the story also reveals that for all his noble intentions, this version of Booster Gold is still something of a scoundrel and has a long way to go before becoming the Greatest Hero You've Never Heard Of.
The Arrowverse version of Booster Gold was introduced in Legends of Tomorrow's season 7 finale, played by Scrubs' Donald Faison. Introducing himself to the Legends as «Mike» (in a nod to Booster's comic book secret identity of Michael Carter), this version of Booster Gold is a time cop assigned to act as a fixed point guardian of the incident that inspired Dr. Gwyn Davies (Matt Ryan) to discover time travel. Mike seemingly goes crazy with the revelation that his job is essentially pointless, as no sensible time traveler would be stupid enough to try and change the fixed point responsible for making time travel possible. He abandons his post, stealing the Legends' time-ship to make his escape. The episode ends with Mike returning to the Legends, seemingly having come to his senses, but really helping his bosses set an ambush to arrest the Legends for their crimes against the timeline. This would have led to Donald Faison wearing Booster Gold's armor had Legends of Tomorrow not been canceled after seven seasons, ending the show on a cliffhanger.
