    Captain Boomerang vs The Flash

    On February 1, 2023, Mercer was freed by Red Death and given a series of advanced boomerangs. With a powerful arsenal, Mercer attempted to steal the Roemer Accelerator fuel source from a Kord Industries convoy. His robbery alerted The Flash, who arrived and mistakenly threw a lightning bolt at the accelerator, starting a chain of time loops.[1]

    The Flash phases the city from the explosion

    In the time loops, Mercer's robbery attempts ultimately led to countless explosions due to The Flash's Speed Force lightning interacting with the core. Thankfully, The Flash and Iris West-Allen came up with a plan to prevent the tampering of the core, though they were surprised when Mercer had a backup detonator for the accelerator. The Flash was able to phase the entire city from the nuclear blast, while Mercer escaped from the scene.[1]

    Returning to Red Death's lair, Mercer demanded that he require more boomerangs, and was subsequently given a crate of said boomerangs.[1] Mercer continued to work with Red Death, later aiding Andrea Wozzeck in her attempt to retrieve Hartley Rathaway's Sonic Gauntlets and restoring Red Death to a stabilized body.[2]
