Thunderbolts #6 pretty much serves as a book end for the first story arc, tying up the first five issues and setting up what comes next. It turns out that the real reason there was so much interest in Kata Jaya was that the American government had been secretly running a gamma base there for quite some time. Knowing that, everything else finally starts to make sense.
The Leader had uploaded his brain all over the internet and now knows nothing of his past. His brother, Mad Man knew that and teamed up with the Kata Jayan government. If they could create a living network of computers–in this case, people plugged into a computer network–only then could they begin to relearn what the Leader had once known. And in this case, it was gamma powered weaponry.
That ghost like figure from the last issue was Mercy who reminds Red Hulk that he can’t just kill the Leader. Mad Man also tries one last time to stop the Thunderbolts, but meets a gruesome demise when they plug him into the human server network and he literally dies of information overload. His head explodes.
Everyone comes to the realization that even though Mad Man has been taken out, whatever he was working on is no longer on the island. There’s a lot of mistrust amongst the team, especially since Red Hulk has been so secretive about the nature of the mission and the fact that they have to pretty much babysit a brain-dead Leader. Punisher and Elektra seem to be happy with their friends with benefits, which makes Deadpool insanely jealous. Doesn’t he know that he’s disgusting.
One of the things I’ve noticed through these last six issues is how much Venom is the moral compass of this book, something the Eddie Brock version of the character could never be. Flash Thompson has made a fine addition to that character’s host-ship.
