Every Major Gotham Villain Ranked From Worst To Best
8. The Mad Hatter
Jervis Tetch A.K.A. The Mad Hatter is one dangerous villain. He's a deranged hypnotist who starts the series by tirelessly searching for his sister Alice who happens to be a carrier for a rage inducing virus. He incessantly pursues her while also stringing James Gordon along in a dangerous game of cat and mouse.
His unhinged psyche becomes clear when he joins up with Jerome Valeska and drags the Police Department into their deadly schemes. He might be quite mad but Tetch easily breaks Jerome out of Arkham Asylum with a horde of other inmates that cause chaos across the city.
If that wasn't bad enough, Tetch also manages to hypnotise the majority of the city's population into lining the rooftops to jump to their deaths on his command. Managing to hold a entire city hostage and break out of the asylum within an evening? Even James Gordon has to be impressed by that one.
