riddler
"Batman says the Riddler is like an artichoke, and you have to pull leaves to get to the heart."
"The Riddler is like a nerdier, less menacing version of The Joker. Mr. Freeze: great tragic villain, but too sci-fi for Nolan's world."
"Every great villain is a foil for a great hero, and Batman is the world's greatest detective. The Riddler is like Moriarty to Batman's Sherlock - setting a diabolical challenge to his mind - and forcing Batman to work his intellect as hard as his muscles."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
