7. Hemo-Goblin
(New Guardians, DC Comics)
Look, I tried to leave one-off characters off this list, wanting to focus on characters that were actually used in comic books. But I'm making an exception for this guy, because his creation and usage is despicable.
He comes from the New Guardians, which was a forgettable team book spun out of a forgettable event called Millennium. The comic attempted to tell stories about "real issues" through comic book antics. This is why a previous issue gave us Snowflame, a supervillain literally powered by cocaine. And while that's fantastic and amazing and beautiful and I love it"¦this dude was their attempt to talk about HIV.
And of course, they did it in the most respectful way possible: He’s a white supremacist vampire who gives people AIDS. That's, uh"¦That's awful. That's not just disrespectful of a deeply serious situation, it’s troublingly simplistic. He gave HIV to several members of the New Guardians team. Through his vampirism. Also, his name is a pun. And not even a good pun.
He's currently rated by the War Rocket Ajax podcast as the worst character of all time, which is logical and makes sense. I, however, know some who are worse.
