  ## Powers and abilities
  
  Originally, Jackhammer is an accomplished engineer and inventor, who wears devices similar to the Shocker's vibro-shock gauntlets. They increase the concussive force of his blows by generating pulsed vibrations on contact. Now, he received immense physical attributes due to the Power Broker treatment, but it somewhat diminished his mind.
