The Bat-Knights of Elvara are a race of 6-inch tall bat riding, cave dwelling humanoids who fought the Atom (Ray Palmer). Elvaran Bat Knights use high tech "electrolances", and appear to have a technologically advanced society. Although Ray Palmer sealed up one of their surface access tunnels, he states that there may in fact be others. They have a racial hatred of normal-sized humans, which causes them to attack any they see. Yet they are the pawns of Eddie Gordon.
