Michael Jon Carter, better known as Booster Gold, is a time traveler and a superhero. He is close friends with Ted Kord.
Injustice 2[]
Booster Gold came to say his farewells to Ted Kord and alluded to his upcoming demise. He helped Ted prepare but couldn't intervene as he had already tried three times and was several years older than the version of him from their last meeting due to the consequences. Before he left, he reassured Ted that he'd be there at the end.
Booster Gold visited Ted during his last living minutes.
Booster Gold visits Blue Beetle weeks later (hours for him) to be his mentor as he promised to Ted. Booster and Blue Beetle received later that night a message from Skeets that both of them will be responsible for Ra's his downfall.
Booster Gold, Starfire, Superboy, and Wonder Girl later meet up with Blue Beetle in an attempt to recruit him to the Teen Titans, Jaime wants to postpone his decision and the Titans leave asking him to think about it. However, Booster and Jamie are suddenly ambushed by Lobo, who captures Jamie to take him to Metron. Booster and the Titans break into the Hall of Justice and steal the Javelin to rescue Blue Beetle. When they reunite, Metron informs them all that the universe requires Blue Beetle's scarab in order to defeat Starro the conqueror.
Metron teleports them all to Oa, where the Green Lantern Corps is being desolated by the Red Lantern Corps. While the Titans engage the fighting, Jamie stays behind from feeling insecure about his control over the scarab. Booster stays behind and inspires Jamie to join the war. The three would chase after Starro to stop the conqueror from reaching Earth. While they pursue, Skeets determines the future isn't fixed and the fight could end anyway, meanwhile, Booster himself has a new memory of his death but he refuses to indulge it. Despite their best efforts, they are not powerful enough to defeat Starro until Jaime asks the Scarab to tell him how to beat Starro. Booster observes and is horrified to see Jamie remove his Scarab in order to sacrifice his life to defeat Starro. Booster reach's Jamie's floating body, and he gives Jamie his oxygen mask and orders Skeets to get Jamie to safety. Booster awaits his fate, but is then surprised when a temporal portal is opened by another version of himself. A past version of Ted Kord greets him. Ted explains because of the rules of time-travel, he cannot intervene to save Booster's life. Despite that, Ted can at least say goodbye to his best friend and waits beside Booster until he passes.
