Well, the Riddler's origin story is quite interesting. He probably grew up in Gotham, feeling overlooked or underestimated. His high intelligence was his main asset, but instead of using it for good, he turned to crime. He created elaborate riddles as a form of psychological warfare against his opponents, especially Batman. It was his way of showing off his smarts and also making the police and Batman dance to his tune. He might have had some early experiences that made him bitter towards society, leading him to this path of villainy.
Definitely. Both the Riddler and Hush are familiar figures in comics. They have distinct characteristics and play significant roles in various comic story arcs.
One key element is his intelligence. His high IQ led him to create riddles. Another is his likely sense of alienation from society, which drove him to villainy.
The Riddler is a fascinating character in the Batman universe. His stories are full of mind - benders. One of the best riddler stories might be his first encounter with Batman. He challenges Batman with his complex riddles, which not only tests Batman's intelligence but also adds a unique flavor to the story.
It's not a straightforward yes or no. The Riddler's behavior regarding killing in the comics is inconsistent. Sometimes he's driven to extreme measures and takes lives, while in other instances, he refrains from outright murder and sticks to his intellectual challenges.
