A comment from a past cast member of CW's The Flash suggests that all of the speedster villains from the show's previous seasons will return to once again go a few rounds with Barry Allen in the show's upcoming 100th episode.

DC World writer Paul Edwards attended an autograph signing at MCM Comic Con London. While there, he talked with actor Tony Todd, who previously provided the voice for Flash villain Zoom. During a conversation about Todd's acting, the former Candyman star explained that he had just finished filming episode 100 of Flash. When asked if he would be reprising his role as Zoom, Todd replied, "They are all returning, all the speedster villains, and they all want a piece of Barry."

This would certainly mean bad news for the Flash, as he has faced more than his fair share of evil speedsters over his series' previous four seasons. In addition to Zoom, Barry has also had to go up against the Reverse-Flash, Savitar, Trajectory and the Rival.

Executive producer Todd Helbing teased a big twist for the series at this year's Comic-Con International in San Diego, so this might be what he was referring to. The eighth episode of Flash Season 5, which will premiere on Dec. 4, will be the series' 100th episode. Tom Cavanagh, who plays various versions of Harrison Wells on the show, will direct.
