The life of forensic scientist Barry Allen (Grant Gustin) went into turbo mode when a particle accelerator explosion triggered a biochemical transformation that made him the fastest man alive. But now he's got to defend Central City from a rogue's gallery of equally superhuman beings and find a way to reverse the singularity brewing overhead. This complete Season 2 collection on six DVDs includes nearly three hours of extras including featurettes, gag reels, the 2015 Comic-Con panel, deleted scenes and more.

Portland homicide detective Nick Burkhardt (David Giuntoli) knew his job meant serving and protecting the human world, but the day he learned he was one of a long line of supernatural guardians charged with policing the "wesen" (the unseen beings known only from fairy tales and folklore), his whole life changed. Extras include deleted scenes, gag reels, featurettes and more.
