It's not clear yet as to whether the suit is for a new hero that'll emerge in the crossover, or whether it's simply an upgraded costume for a hero we're already familiar with. It's not immediately obvious which hero would wear this suit, which suggests it'll be for a new inclusion to the huge roster of heroes we've been introduced to thus far. Perhaps the Elongated Man will get a leather suit much like his fellow vigilantes don.

Arrow and Legends producer @marcguggenheim shared this photo teasing that they already started working on the Arrowverse crossover for this year! Can't say what it is of course but cool things are coming so so tune and be patient! I have also officially finished my first few concept on suoergirl, so I guess I have officially crossed over all 4 shows as well! @cw_arrow @cwtheflash @cw_legendsoftomorrow @supergirlcw #concept #design #illustration #arrowverse #crossover #dctvuniverse @cwseed @dccomics @gberlanti #berlantiverse @vancouverfilmstudios #comic #superhero #nerd #fanboy A post shared by Andy Poon (@andypoondesign) on

Elongated Man, who will be played by Hartley Sawyer, is set to debut in The Flash when it returns for its fourth season. It'd be strange for the DC Comics character to not receive a supersuit when he inevitably reveals his powers to Barry, especially with the official character description hints he'll help make Central City a better place.

“One of the Flash’s most iconic allies, Ralph Dibny — a.k.a. The Elongated Man — is a fast-talking private investigator with investigative skills that rival those of Batman. Upon discovering he has the power to stretch his body to any shape or form, Dibny uses his new abilities to help Team Flash solve one of Central City’s greatest mysteries.”
