The Penguin

The Penguin was one of the many people who attacked Wayne Slater during his special training, along with two of his henchmen. Wayne used The Penguin's umbrella against him, spraying the trio with gas which knocked them out.

Behind the Laughter

 * The Penguin is a villain from Batman.
 * One of The Penguin's personal tradmarks is his wide assortment of umbrellas which contain a variety of weapons, such as swords, machine guns and (as Wayne demonstrates) knockout gas, somewhat similar to Batman's utility belt.
