- "Oh let us eggsplore Gotham City's Sewer System!"
Eddy G. Heed AKA Egghead was a major enemy of the Dynamic Duo that believed himself to be "the world's smartest man alive." His crimes usually have an egg-motif to them as well as including egg puns in his speech where appropriate such as "egg-zactly" and "egg-cellent." Egghead is instantly identifiable by his pale bald head and white and yellow suit. He is based on a villain who faced Batman once called Barney Barrow.
Fans suspect that He was bullied as a kid due to his egg sized head and when he grew up, he took it to the Egg-streme and renamed his villainous identity after his childhood nickname.
Additionally, he would use a wide assortment of egg-shaped weapons, such as laughing gas eggs and tear gas eggs (laid by chickens on a diet of onions).
