So...my greatest fear, next to Guy getting killed off in Blackest Night, is Ted Kord coming back as a Black Lantern. I thought that Geoff Johns had assured us that Ted was actually ALIVE! I've been trying to keep believing in it, but rumors keep persisting.
If Ted Kord DID come back as a Black Lantern, I would have to say that the heroes of the world would be in for a world of trouble. Remember all the havoc that he and Booster managed to cause when they were alive and GOOD? The concept of an Evil Ted is...terrifying.
Here's a small example of what Ted could do when he wasn't in his right mind. This is from the old JLI, when Ted was being mind-controlled by that mean old Queen from Bialya into doing her wicked biding. He's actually beating up Amanda Waller. Amanda Waller! She intimidates Batman, for God's sake! And this is with no super powers whatsoever.
Be afraid Booster. Be very very afraid.
