Elias Wirtham was a doctor driven by his brother’s death to research life-saving medical practices. His brother’s death was the result of corporate greed, who had a cure for his condition ready, but did not distribute the medicine due to it not being a “profitable” time for them, hence his motivation against corporations. As a part of his research, Elias replaces his heart with a beta-particle reactor, which supplies energy throughout his body, in addition to a vibranium weave mesh under his skin. This energy, channeled through his muscles, increases his speed, agility, and reflexes, and can also be fired through his fists or the power staff he wields. He adopts the moniker “Cardiac” in reference to the source of his power. Wirtham is a physician and surgeon, and the owner and administrator of a biological research firm. He’s clashed with Spider-man and Rhino among others. Before the death of Nightwatch the two also became friends.
