Voodoo is pretty cool. She calls herself Priscilla. Her goal: study humanity in order to aid in their destruction. Her race or group of extraterrestrials are shape-shifters and quite clever. Its hard to tell if they have a definite form - they all look different. Issue number three really dabbles more into their intent and ability. Green Lantern is suppose to be equipped with information about all lifeforms, but he knows nothing of Voodoo's people.
Voodoo is going to study the heroes of the DC universe. The series seems like it will follow her around the world as she wanders and gathers intelligence. She is very dull and cold. She isn't a hero, but she's not really a villain. I'm curious as to what her personality will develop into. It is as if Marvel gave the Skrulls or a Skrull their own series. DC might have stumbled onto something great. The art is also very very awesome! Keep an eye out for this series! 4/5
