Joseph "Joey" Monteleone, nicknamed Tar Pit by Cisco Ramon, is a meta-human from Central City with the power to generate heated tar from his body. Just prior to the S.T.A.R. Labs particle accelerator explosion, Joseph was dropped into a tar pit by Daniel Burge and Clay Stanley, leading to him being affected moments later by its shockwave. Joseph spent two years trapped in the ground, but he was able to get out when a construction crew made a hole in the ground. In an act of vigilantism Joseph proceeded to hunt down and punish the men responsible for his near death.
