This. The Arkham games did a great job with this despite all those damn trophies. Riddler pretty much exists to prove he's better than Batman. He could give 0 fukks if its not gonna get Batman's attention.Arkham games showed that his Riddles could be more than just verbal though.
Mr. Freeze is the one that ain't shyt. I mean, just look at his fukkin name?
He doin it for his wife bruh
