The Riddler: You never really understand this type of co-worker. Sometimes he’s nice, sometimes unfriendly, sometimes knowledgeable, and sometimes dumb. The Riddler smokes and drinks and eats, but so irregularly that you wonder if he’s a smoker, or a drinker (or an eater).

Invisible Woman: The Invisible Woman (pictured below) is largely unnoticed in your office. She’s on the payroll, so everyone understands she’s somehow doing a good job, though no one understands exactly what this job is. Invisible Woman will avoid all after-work socialization, quietly leaving when work is done. The Invisible Woman doesn’t need to call in sick as no one will notice her missing anyway.

The Punisher: The Punisher is usually higher up in the hierarchy as he likes to bully people. When you did something wrong, The Punisher arrives on the scene to make you feel it by use of excessive force. Sometimes, when there’s two Punishers in one office, a no holds barred battle is going to erupt.
