Fan Casting "The Joker" in Batman V Supergirl: Injustice

After being critically injured and left to die in his fight with Supergirl, Thomas Wayne is soon assisted by Bruce, who is then smashed into the wall, courtesy of a sonic blast that hit him from behind. Batman looks to the shadows, and makes out three figures emerging from the darkness, one of them in a green suit, one with brown and grey hair, and one dressed as a clown with a smile carved into her face. The one with the carved smile says, "Do you want to participate in our little game, Batman?" The clown asks, laughing hysterically afterward.
