Which One Chicago season had the worst villain?

Chicago Fire, Chicago PD and Chicago Med all had recurring villains who drove One Chicago fans crazy this season, but which antagonist was the worst?

The three One Chicago shows had something else in common this season: they all had a major villain who caused a whole lot of trouble.

Chicago Med, Chicago Fire and Chicago PD each used a similar template this most recent season when it came to their antagonists. They introduced a recurring guest star, whose character had a backstory with one of the main characters, and who eventually revealed themselves to be fixated on beating or otherwise tearing down one of the show’s heroes. Obsessed, self-centered and above all ruthless, they didn’t care about anything but causing problems in our fandom.

Plus, they were all incredibly frustrating for One Chicago fans to watch, too.

All of these characters got on the audience’s nerves and all of them caused significant damage on their respective shows—so we’ve decided to compare their unenviable resumes and see which of them was the worst.

Was it Denny Woods, Carl Grissom or Robert Haywood who took the crown as the least wanted person in One Chicago? Fans would be perfectly happy to see the back of all of them, but which one do you wish we’d never seen to begin with?
