Velma is the brains of the operation. She is usually the one who deciphers all the clues and discovers the truth behind the mysteries. She tends to be depicted as slightly heavier set than Daphne and definitely does not have Daphne's fashion sense. She wears glasses and is completely blind without them and she also knows her way around a computer. Her trademark lines include 'Jinkies' and 'Are you thinking what I'm thinking' among others.
