Demise
Vengeance League had been invesitgating crimes in and around Chicago and had determined that the local Nazi party was at fault. After some investigating it was determined that they had one Prime, Ubermann, and their leader, Malachite, was suspected of being one.
After a clash with a single agent left the entire Vengeance League team battered, Buckethead theorized that this agent was either also an extremely powerful Prime, or he was being aided in some way they could not detect. Some investigation by The Executioner led to damning evidence that proved that Malachite was only manipulating and using the Nazis, and also indirectly showed that they were not culpable for the crimes themselves.
As a whole Vengeance League was torn about how to handle this. Nazis have a stigma associated with them, so arresting them would have served well in public opinion, but would certainly have allowed Malachite to escape. In a risky maneuver The Executioner contacted Nazi leadership and released his evidence to them. After some consideration they agreed to assist one another to bring Malachite to justice.
During the final showdown Malachite proved too shrewd for even the combined might of both allies. He escaped with his closest associates, though some mercenaries he hired were captured. They proved to be severely brainwashed, and no usable information was obtained from them.
