Death of Dr. Hart
Zero Fluid was conceptualized and developed by the brilliant scientist, Dr. Hart, as a revolutionary energy source with the potential to redefine the world's power dynamics.[1]
The Contraxian alien race dispatched many scientists to try to discover an energy source to resuscitate the dwindling nuclear processes of the Contraxian sun. Learning of Hart's experiments, one of the alien assumed a totally human form to keep Hart under surveillance. Hart and the alien eventually met, married, and produced a son they named Jack. The alien woman, "Marie," died in a car accident when the boy was a child. Jack grew up without knowing of his mother's origins.[2]

Zero Fluid's unstable explosive nature
However, tragedy struck when the Corporation seeking to steal the technology killed Jack's father and doused Jack himself in the Zero Fluid during the altercation. This incident resulted in Jack gaining extraordinary abilities. His powers include enhanced strength, rapid healing capabilities, the ability to release explosive energy, flight, and even the remarkable capability to traverse through space. Jack's newfound abilities propelled him into the role of a formidable vigilante, seeking justice for his father's murder. In honor of his father's passion for playing cards, Jack adopted the moniker "Jack of Hearts" as he embarked on his journey to mete out justice and protect the innocent. Recognizing the immense energy coursing through Jack's body, he dons a specially crafted suit of armor designed to contain and regulate his powers. This armor serves as both a protective shield against external threats and a means of harnessing and controlling Jack's formidable energy output.[1]
Throughout his crusade, Jack frequently collaborated with Ant-Man, who sought to find a cure for Jack's condition. In a heroic act, Jack sacrificed himself to save Ant-Man's daughter.[3]
However, his resurrection by the Scarlet Witch resulted in a catastrophic explosion due to the overwhelming energy contained within him. This tragic event not only claimed the life of Ant-Man but also devastated the Avengers Mansion and its surroundings.[4]
