| Synopsis | It's full-throttle war with the Masters of Evil as the Thunderbolts attack their namesakes in a take-no-prisoners style! And, in the aftermath, a mysterious cloaked figure appears who will change the T-Bolts' life forever! Like THUNDERBOLTS #10, it's another status quo- shattering shocker for Marvel's mightiest miscreants, setting the stage for the AVENGERS/THUNDERBOLTS conflict coming in two months!
