Hal and Guy Vs. The Guardians!
Hal Jordan is channelling the power of Fear while Guy Gardner is powered by Rage, but neither of them can stand up to The Guardians infused with all of the powers of the emotional spectrum! While the leaders of the Corps try to battle their way out of The Book of Black, Jordan and Gardner find themselves at the evil Krona's will, and soon to be hyper evolved into the new guardians of the universe.
Written by Geoff Johns and drawn by Doug Mahnke, the continuation of the Green Lantern event "War of the Green Lanterns" hits its 7th installment with another large twist. Krona doesn't just want to control all of the elemental powers in the spectrum, he wants to replace those who control them. The Earth Lanterns are the most versed in the realm of controlling and embracing emotion, so it would make sense for him to target Jordan, Gardner, Stewart, and Rayner as his right hand men.
This issue was mainly a taste of things to come, raising the stakes before moving on to a much bigger climatic showdown. It's still a wonderful read, and you get to experience what it's like for Sinestro and the others to be trapped in The Book of Black, which contains all of the prophecies dealing with the different Lantern Corps.
It's also interesting to see Jordan and Gardner embrace their darker sides in order to use their new powers. Jordan has always fought against the fear inside of himself in order to be who he is, and now he's forced to use it as a weapon. Gardner has always been a hot-headed vigilante, and how his rage is all that's keeping him alive. Johns keeps building the Lantern mythology to staggering heights, and it's transformed the series and the characters into a modern science fiction epic.
