1. Lock-Up
Harley Quinn might be the most famous Batman character to originate in the Animated Series, but she isn’t the only one! No, that category also includes Lyle Bolton, aka Lock-Up.
In his original animated identity, Lyle was a security expert hired to stop the systemic tide of escapes from Arkham. He liked to do this through extreme – and often illegal – force, which got him fired. So he set out for revenge, and fought Batman and Robin.
In the comics, he first appeared as a mysterious vigilante who was abducting villains before Batman and Robin could and taking them to a secret prison. This Lyle Bolton was a failed cop and security guard who was fired from multiple jobs for using extreme force. He later took control of Blackgate during the Gotham Earthquakes, and broke prisoners out for the Battle of Metropolis. Not the most famous guy, but still a notable one.
And there you have it, ten Batman villains who have been forgotten to the sands of time, and why I love them. Seriously, these guys should be used sometime soon. They’re all great!
