What a very strange sequence of events. So Booster Gold goes back in time and saves Batman’s parents from being murdered. Why? Because he thought giving Batman a timeline where he grows up normal with his parents was the perfect wedding gift. But when the time came to take Bruce Wayne back and fix the timeline, Bruce destroyed Skeets, Booster’s companion and time machine, and chose to live out this fake timeline. I call it Boosterpoint to differentiate it from the other alternate timelines.
So Booster Gold decides to spring Catwoman from jail thinking that if Batman sees her, he’ll remember his love for her and come to his senses. The only problem is Catwoman turned out to be a psychopath with a grudge against Thomas Wayne. While she was savaging him with her sharp claws, the Batman in this alternate timeline decides to join in on the fray. It’s Dick Grayson with a serious Jason Todd attitude as you can tell with the guns.
After the dust settled, we get the catalyst for Bruce Wayne becoming Batman in the first place.
