A key feature of this logo is how the letter "R" in "Riddler" is cleverly designed to form a question mark. The flourish of the "R" creates the curve of the question mark, while the dot below it completes the iconic symbol. This design choice is a direct nod to The Riddler's defining characteristic: his compulsion to leave riddles and clues. It represents his intelligence and his need to feel intellectually superior, all while hinting at the secrets hidden within his complex persona.
