A dark era for the ever-changing Thunderbolts! In the aftermath of CIVIL WAR, the country has lost faith in its heroes - and it's ready to put its faith in monsters! As Norman Osborn assembles his new team of Thunderbolts, Songbird and Moonstone must learn how to work alongside vicious killers like Bullseye and Venom! And the Skrull Secret Invasion might be just the opportunity Osborn has been waiting for to take his plans to the next level! A whole new squad includes Yelena Belova, the Irredeemable Ant-Man and the Ghost - but when Deadpool targets Norman Osborn, which side will the unpredictable Thunderbolts take? Plus: solo adventures of key members, including the mysterious Penance! And a super-villain fight club turns the T-bolts concept on its head!
