Want to write a crossover with DC/Batfamily, but I’m not too well versed in their dynamics

Basically I want to write a The Boys x Batfamily crossover in which the cast of The Boys gets thrown into Gotham, and you know how well that might go, but as much as I’m familiar with The Boys’ universe and characters due to watching the show, my knowledge of Batman is limited to The Dark Knight movies and the newest Matt Reeves movie. I have only surface level knowledge of the Batman rogues gallery, members of the Batfamily, dynamics of Gotham etc. Are there any resources/essays/wikis I can read to familiarise myself with it and be able to be more authentic in my fic?
