On request of the Commission on Superhuman Activities, Conrad joined their Redeemer Program to become the Smuggler. What the Commission offered Conrad and what they actually gave him is up to debate. The CSA gave Conrad a suit that allowed him to access the darkforce dimension to melt into shadows. The Redeemers (led by Helmut Zemo who had taken control of the body of John Watkins III aka Citizen V) eventually fought the Thunderbolts and they discovered his identity. After the battle was over the Thunderbolts were offered pardons (including Atlas despite his apparent death) and disbanded. The Redeemers then began to operate out of the Thunderbolts headquarters Mount Charteris in Burton Canyon, Colorado under the guidance of Captain America working for the CSA and S.H.I.E.L.D. In exchange they would have eventually been pardoned for their past crimes (there is some question as to if Conrad needed a pardon for himself or if needed one for Erik. Erik already got one from the CSA but Conrad might not have known that). The majority of the Redeemers were slaughtered by the villain Graviton and Conrad was believed to have been killed when Graviton shunted him into the sun. It was later discovered that Conrad had escaped into the darkforce dimension but became trapped there.
Baron Zemo eventually discovered Conrad's fate and arranged to have Blackout brought back from the dead so he could tap into the darkforce dimension and free Conrad. Zemo offered Atlas a choice, side with him and let him kill Genis (to save the universe) or he would leave Conrad in the darkforce dimension forever. Erik sided with Zemo and after Zemo killed Genis Erik was rewarded with Conrad's freedom. Conrad joined the Thunderbolts and seems to want to repair his relationship with his brother Erik.
As of the end of the current run of Thunderbolts Conrad's Darkforce suit has been destroyed by the Wellspring energies that Zemo released.
