In the emphatic words of Lyla Michaels: The Crisis has begun. And begin is exactly what it did as it unleashed its fury - in the form of a wave of antimatter - across the multiverse, destroying countless earths and universes that unfortunately found themselves in its way.
Among those planetary fatalities was Earth-38 - the home of Supergirl and her Super-Friends - but not before they (and their interdimensional super-friends) evacuated almost half of the planet and breached them to the final target in the antimatter's path - Earth-1.
With a little more time, the heroes should have been able to efficiently plan their next moves, but the unexpected death of the Green Arrow has left them a little uncertain of what comes next, and it's up to Kate Kane to track down a different moody billionaire superhero in order to get some answers.
Batwoman's offering of the crossover successfully follows a strong opener, as 'Crisis On Infinite Earths, Part Two' introduces us to Kevin Conroy's Bruce Wayne, Kingdom Come's Superman and allows us to catch up with some of our Smallville favourites in a surprisingly character-driven affair - all while managing to bring the main villain into play.
