This is still one of my favorite comics of all time. This book shows humor that you don't often see in superhero comics and most of it comes from the interaction between the heroes. Every character has a distinct personality that doesn’t mesh with the group, Batman is the frustrated leader, Guy Gardner is the 80s action star, Black Canary is the feminist, Captain Marvel is the innocent child, Martian Manhunter is a former leader with survivor’s guilt, Blue Beetle just wants to be taken seriously, Dr. Fate acts as Batman’s right hand, and Dr. Light is the diplomat.
Back in the 90s, DC ran different themes with its annuals, one year it was Elseworlds stories, one year it was an alien invasion with Armageddon. In 1993, it was Bloodlines. DC had a universe-spanning annuals theme that featured aliens attacking humans sucking out their spinal fluid and leaving the the unlucky ones that survived with superpowers. It was meant to create new, exciting characters but the only notable character that came from this storyline was Hitman. This book features Jean Paul Valley, Azrael, as Batman but before he adopted the entire costume.
