10 Most Disturbing Supervillains That You’ve Never Heard Of
7. Cornelius Stirk
Proving that some kind of weird fixation is a legal requirement to get into Gotham, Cornelius Stirk is in many regards yet another madman, aside from the small detail of his obsession with eating human hearts, fresh from the source. Not just any old human hearts, either, as Cornelius is a connoisseur, insisting on eating only hearts that have been harvested from people who experience great fear before they're killed.
It appears that this cannibalistic compulsion is used to power Stirk's abilities, as the serial killer is able to not only alter how he appears to other people, but also to mess with their minds and fill them with fear - which is convenient, given it's his preference to how he eats his meat.
It's almost a shame Cornelius is so underused, as he's so genuinely creepy that having him appear more in comics would add an extra bit of variety to the reappearing creeps on Batman's beatdown list.
