In Brad Meltzer's Justice League of America, Grundy is reborn with intelligence after being killed in the Battle of Metropolis.[34] He is revealed to be the mastermind behind the abduction of Red Tornado's robot body (it is revealed he gained this intelligence when he was reborn after being burned by Prime). Grundy expresses a desire to stop his cycle of dying and being reborn and so it appears he enlists the help of Professor Ivo to build him an Amazo body to live in forever. The Red Tornado kills Grundy with F5 tornado winds, ripping him apart.[35]
