10 Comic Book Heroes Who Died Horrible Deaths

10. Jack Of Hearts Kills Ant-Man

Jack Hart was a hero who never quite got the “Zero Fluid” energy that permeated half his body under control. The power fluctuated from being powerful enough to replace the Hydrogen in the Contraxian sun, to being barely enough to sustain his form.

His power drained the gamma energy from She-Hulk, forcing her to revert to her Jennifer Walters form, and then was able to use his powers to balance her radiation to balance her savage side. Jack was losing control of his energy again and had to spend several hours a day in a containment chamber to hold his energy at bay, which made him resentful and aggressive. After a while, even that stopped working for him and Jack left the planet lest he exploded.

At some point, before Scarlet Witch began to have her mental breakdown, Hart died. Wanda somehow directed his zombified corpse to return to the Avengers mansion. The Avengers were having breakfast and Scott Lang, the second Ant-Man, was the first to notice Jack and confront him on the lawn. Scott barely got a few sentences out before Jack exploded, killing Lang and destroying most of the mansion. This was just the beginning incident of what became the Avengers: Disassembled story arc that completely destroyed the team.
