Finding Sandy injured, the Sandman became enraged and rallied the remaining police to charge after the criminals.  Arriving as the Vikings boarded the boat and removed their armor, the tides shifted in the favor of the law. The sound of the battle attracted reinforcements and after a significant effort, all the Fenton’s gang was brought to heel.  The next day, as Sandy was being discharged from the hospital, Fenton, in a body cast, was brought in raving about dreams of Sandman before being returned to prison (Adventure Comics #75).

A short time later, Fenton was liberated by the Ultra-Humanite to join a team of villains he was assembling.  The Humanite had become aware of a mallet created by an elder race that Hawkman had acquired as part of his collection of weapons.  He had used the mallet against criminals masquerading as fire creatures and lost it in a volcano.  Fenton was charged with retrieving the weapon also known as the “hammer of Thor” but the energy from it unhinged his mind, already weakened from constant nightmares about Sandman.  He lapsed more fully into his identity as Thor and sought to punish the hero who has bested him.

Stalking the rooftops of New York, he spied the Tarantula who in those days was garbed in a yellow and purple costume that closely resembled Sandman’s.  Spying the hero swing into JSA headquarters, Fenton attacked the assembled heroes who were instead members of the All-Star Squadron.  His weapon far more powerful than his previous hammer, Fenton held off heroes as powerful as  Robotman and Steel until the Tarantula goaded him into smashing his fist into electrical conduits in the wall.  The massive charge subdued Fenton and he was separated from the hammer and returned to prison (All-Star Squadron #18).  The hammer was later stolen by Cyclotron and taken to the Ultra-Humanite (All-Star Squadron #21). 

The later activities and final fate of the “Villain of Valhalla” are unrevealed.
