This thick volume collects the first 17 issues of the series, which starts 35 years from now, in which a great many of the Superheroes have been killed or assimilated by Brother Eye, which has transformed them into robotic, Borg-like creatures. To prevent this horrible future from happening an elderly Bruce Wayne/Batman sends "Batman Beyond" back into the past, which turns out to be five years from our future, after "the War" with Apokolips has occurred. Lots of things have happened, including the death of Green Arrow. Perhaps the most interesting sub-plot is that of Ronny Raymond, half of FIRESTORM, who has turned into a complete douche-bag. I found this an interesting read, particularly in that it introduces the television animated character into the mainstream DC Comics Universe. Recommended.
