As much as this poster shows alot of awsomness, there is still the comic book guy in me that is yelling out that thisnis wrong. Sadly you cannot join the Green Lantern Corps, you are chosen, other words drafted. If you have the willpower, then you may be chosen. But remember this, if you got a ring that means a Lantern was killed in action. And you hope that the Lantern was able to beat it before he died or another Lantern was assisting and neutralized it.
