Jack Hart, better known as Jack of Hearts, is a Marvel Comics superhero. He gained his powers after an accident involving Zero Fluid, a substance created by his scientist father, Philip Hart.

The Zero Fluid exposure altered Jack's physiology, granting him superhuman strength, speed, durability, and the ability to generate and project concussive energy. His appearance also changed, giving him red skin and energy patterns radiating from his body.

Initially struggling to control his powers and the unstable Zero Fluid energy within him, Jack often required a special containment suit. He fought alongside various superhero teams, including the Avengers, and developed close relationships with his teammates.

Tragically, Jack's powers proved to be ultimately fatal. He was often depicted as a volatile and dangerous character, grappling with the unpredictable nature of his abilities until his death and subsequent returns.
