Cisco Ramon and Ronnie Raymond on Martin Stein[src]

Martin Stein (died February 9, 2016) was a meta-human who was transmuted and conjoined with Ronnie Raymond, who operated as a supervillain known as Deathstorm.


In 2013 after the S.T.A.R. Labs particle accelerator explosion, Martin Stein was exposed to the dark matter and merged with Ronnie Raymond. Ronnie resorted to trapping Stein within his body and refused to change back to their human forms. Eventually, Stein stopped talking to Ronnie and the latter could no longer hear him. Eventually, Ronnie became a villain known as Deathstorm and started working for Francisco Ramon/Reverb, Zoom's right-hand man.

Several years later, Stein was killed by Zoom when Ronnie nearly killed The Flash.[1]
