I Am Not Making This Up

I swear I heard years ago that DC Comics put out a comic book about a superhero with AIDS. Or was that just a rumor?

I know that Batman had a villain who was blind and one of the Teen Titans was deaf and only could speak through sign language.

There's a villain named Hemo-Goblin:

Don't know if that's who you're talking about but it's what I thought of right away.

Perhaps you're thinking of Mia Dearden aka Speedy II? She's the only HIV possitive DC hero I can think of.

The one you are thinking of is Speedy II,Green Arrow's replacement sidekick was around on a reoccuring character a little before about 6 to 7 years as Oliver Queen's sidekick.
