Hank and the other three members of the Excalibur crew, including his wife Terri, are part of a radiation experiment designed by LexCorp that is affected by a solar flare, causing their Shuttle to crash. As a result of their radiation exposure, the human bodies of two crew members were destroyed. However, their minds survived and they were able to construct new bodies out of cosmic radiation and bits of earth and wreckage from the Shuttle, respectively. Initially, Henshaw and his wife suffer no ill effects from the radiation (though Hank's hair turns white), and the crew travels to Metropolis in the hopes of using LexCorp facilities to cure their mutated crew mates. During a brief battle with Superman, one crew member, now composed of radiation, becomes unhinged and flies into the Sun, destroying himself. By this time, Henshaw's body has started to rapidly decay while his wife is beginning to phase into an alternate dimension. With Superman's help, Henshaw is able to use the LexCorp facilities to save Terri. The remaining member of the Shuttle crew commits suicide using an MRI booth to tear apart the metallic components of his body.
