Intimidation means to intimidate. This is a skill which involves scaring someone. This is a very useful ability. Batman often uses this ability to scare the villains into giving up, or force them to talk during an interrogation. sometimes with torture tactics. The very reason Batman dresses up like a bat is because he desires to "strike fear into the hearts of evil doers," which he learned from his studies that it is especially possible for most criminals since they are a "superstitious cowardly lot."
