According to TVLine, on the new CW television series The Flash,  the openly gay villian/superhero The Pied Piper, who will appear “at mid season,”

In addition to the likes of Captains Cold and Boomerang, at midseason we will also meet Hartley, a onetime mentee of Dr. Wells’ who lost his hearing in an accident and now is out to wreak havoc with an invention of his own. (Of course, you may know Hartley — who happens to be gay — as the Pied Piper.)

It’s long been assumed that Piper would appear in the show — partly because of the “prominent gay character” rumors and partially because he’s a key member of the Rogues, who are set to appear this year.

It’s also worth noting that the current version of Pied Piper in the New 52 isn’t deaf; that’s from a previous interpretation of the character.
