Peter Merkel, nicknamed Rag Doll by Cisco Ramon, is a meta-human with the ability to contort his body.


Peter lived with his mother, Theresa Merkel. According to her, he was spoiled and was never happy with how well he was treated. He and his mother would later become estranged after he tried to break into his own home.

On the night of The Enlightenment, Peter was, as he put it, "crushed, snapped, and broken" by pieces of the S.T.A.R. Labs satellite.

After the Enlightenment, Peter attacked many people and committed many crimes, including stealing a family heirloom from a man about to give it to his significant other. He also destroyed a building and nearly killed a man until the Flash saved the man. When Barry Allen and Iris West-Allen appeared at his mother's party, he spied on them from the roof and captured Barry Allen, so Iris and Elongated Man came to save Barry. Iris jumped off of the building to save him while the Elongated Man ate Peter to keep him in his body before the police arrived.[1]

Peter was then incarcerated in Iron Heights Prison where Mark Mardon spoke to him about a breakout.[2]

Peter claimed to be broken inside as the result of his mother inattention's and detachment from him.

Powers and abilities


  • Meta-human physiology: When hit by a dark matter shard from the S.T.A.R. Labs satellite after the failed Enlightenment, Peter's DNA was altered, enabling him to access his newfound powers.
    • Body contortion: Peter has the ability to twist and contort his body in virtually any way he pleases, allowing him to fit into spaces of any size and shape.[1] He even managed to squeeze himself into a suitcase, and through an arm-width pipe.
    • Superhuman durability: Peter's malleable physiology grants him superhuman durability, being capable of surviving an explosion powerful enough to cause an entire rather tall building to collapse, followed by being buried under the rubble of said building.[1]
    • Enhanced strength: Peter has shown to have some level of inhuman strength.


  • Acrobatics: Merkel is very nimble, mostly from his contortion abilities, managed to disarm Joe of his gun with a backflip.
  • Stealth/Infiltration: Merkel was able to sneak up on Barry without him noticing despite the latter being a speedster. He also managed to get the drop on Cisco and Sherlouque while they were in an elevator at S.T.A.R. Labs. His contortionist powers allow him to travel through air vents of a building while avoiding detection.
  • Expert hand-to-hand combatant: Merkel is proven to have at least rudimentary combat skills, able to briefly knock out Iris West-Allen and managed to easily restrain Joe West.

  • Rag Doll mask: As Rag Doll, Merkel wore a mask which resembled both a clown and porcelain doll for purposes of concealing his identity and general intimidation.
