Joseph Monteleone

Joseph "Joey" Monteleone, nicknamed Tar Pit is a meta-human from Central City. Prior to the S.T.A.R. Labs particle accelerator explosion, Joseph was dropped into a tar pit by Daniel Burge and Clay Stanley. After two years of being trapped into the ground, Joseph hunted down the men responsible for his near death.

Early life
As a juvenile, Joseph Monteleone committed a crime that placed him in a juvenile detention center. At the center, Joseph bunked with Daniel Burge.

Particle accelerator accident
Just prior to the S.T.A.R. Labs particle accelerator going off, Joseph was concered into giving him the account number to his money. Despite giving them the account number, Clay Stanley pushed Joseph off of Daniel Burge's arms, falling into a tar pit. As the particle accelerator went off, Joseph was buried beneath the ground for two years, unable to see or feel.

As Tar Pit
After rising from the ground, Joseph found Daniel Burge. Joseph told him the pain he felt, then ultimately made him feel the pain he had felt, killing Daniel.

After killing Daniel, Joseph went after Clay Stanley. The Flash intervened as Joseph was about to kill Clay. Joseph made an attempt to hit the Flash with a blast of fire, but the latter got out of the way, causing Joseph to hit a fire hydrant. The water melted Joseph, subduing him temporarily.

Joseph went after Clark Bronwen next at a drag race. Joseph disguised himself as the pavement, hurling Wally West and his opponent toward Clark. The Flash rescued Clark, but a glass pierced Iris' shoulder in the crossfire.

Outside of the Central City Police Department, Joseph waited as Joe used Clay as bait. Joseph, in a large, monstrous form, hurled a blast of fire toward Clay and Joe, though the two got out of the way in time. The Flash then arrived, hurling two nitrous grenades. Joseph's large form shattered, reverting him back to his previous form, and was knocked unconscious by Joe West.
