'The Flash' is an ongoing superhero television series that premiered in 2014, and is part of The CW's Arrowverse, featuring characters from DC Comics, in this case, Barry Allen/The Flash. Barry Allen, a crime-scene investigator for the Central City Police Department, gains superhuman speed after being struck by lightning, becoming a 'metahuman', and uses them to save Central City, as well as track down the Reverse-Flash, another speedster who killed Barry's mother years ago.

S4E2: Mixed SignalsEdit

With his suit fitted with new gadgets and upgrades, Barry accidentally sets off floatation mode, meant to be used in case he's in water (Cisco, his friend and inventor, not thinking he could just put an oxygen tank in the suit if he loses his speed while on water).

S4E9: Don't RunEdit

Barry activates floation mode as he nears a river in the close of his fight with Clifford DeVoe/The Thinker.
