Jake Simmons also known as Deathbolt might not be the most recognizable villain in the DC comic books but he is said to be unique compared to other "Arrow" and "The Flash" archenemies. Aside from making an appearance in both CW superhero shows, he is also the only metahuman whose powers did not come from the pipeline explosion. Following his downfall in "The Flash", some might say that Deathbolt will no longer be seen again but actor Doug Jones who portrayed his role considers the possibility of his character's return at some point.

Doug Jones actually teased during his interview with Comic Book that there might be a possible way to bring back the character because of the uncertain nature of Deathbolt's end in the show. According to him, after Wentworth Miller's Captain Cold shot him in the face, a question still remains: if his character was really killed or was just silenced for a minute.

"They never really did paint it as a full on death," he said.  "I think I could give the writers some leeway. If I'm busy they don't have to bring me back, if I'm free and available and they want me, I'll return. We'll see."

Last time around, Jake Simmons was one of the few metahumans prisoner the S.T.A.R. Labs team was putting away from the facility. Unfortunately, the truck which was carrying the prisoners has been sabotaged by Snart and his sister Lisa which caused Simmons to escape. According to Cinema Blend, before Simmons nearly killed Flash, he got blasted in the face by Snart's gun. Though it ended with his face blackened by the freezer gun, it was really not verified whether he was truly iced.

Considering death in the world of comic books is not automatically permanent, it gives the possibility that Deathbolt can be brought back if the writers and producers really want to. 

Meanwhile, the second season of "The Flash" is expected to kick off this fall on CW, with the all-new superhero show "Legends of Tomorrow" debuting at midseason.
