The Energizer Bunny
When Duracell allowed their trademark to expire on the pink bunny, Energizer swooped in and filed a trademark for their cottontail. You won’t see the Duracell bunnies stateside anymore, but those original pink battery bunnies can still be seen in Europe. However, much like the Johnny Cash cover of the Nine Inch Nails song “Hurt", most mistake the latter as preceding the former.
The original Energizer Bunny ad also predates the ubiquitous slogan “it keeps going… and going… and going” and instead proclaims “a word to the wise – Energize”. The current slogan is most appropriate, considering that, of the five mascots on this list, only the Energizer Bunny is still collecting checks as a mascot.
