Hammersmith is shown to be an arrogant inventor making weapons and selling them to the highest bidder, until Babylon hired him at first at force, but was willing when he saw the Weapon. He battled M.A.Y.H.E.M. in Seoul, Korea at the planetarium at first but then left like a coward when things didn't go as plan. At his final showdown after his second defeat fled like a coward again, but suffered humiliation, and reprimanding from Babylon for his failure and cowardice.
In a parallel universe created by Babylon inside the Robot, he returned with Gaunt (much to his dismay of partnering with him), both faced M.A.Y.H.E.M., once last time in the battle, he was killed by Rama.
