Fenton Crackshell is a fictional character created by The Walt Disney Company.
He first appeared on Duck Tales as a bean counter (literally) but he quit that job to work for Scrooge McDuck as his accountant. Later on, Fenton found a robot suit called Gizmo Duck made by Gyro Gearloose. The code word to activate it was "Blatherskite," a word which Gearloose assumed no one normal would use (unbeknownst to him, one of Fenton's most frequently used sayings was "Blathering blatherskite.") As fate would have it, Fenton wandered too close to the suit and uttered his favorite expression, thus gaining a secret identity. The only characters privileged to know that Fenton is Gizmo Duck are Scrooge McDuck, Gyro, and Fenton's mother whom he refers to as M'ma. Fenton is in love with Gandra Dee, Scrooge's bean factory receptionist. As Fenton he is Scrooge's accountant but as Gizmo Duck he is Scrooge's security guard and personal body guard. Fenton also has the surprisingly useful, almost superhuman natural ability to count a large number of objects instantaneously. Fenton has appeared as a guest star on Darkwing Duck on occasion as Launchpad McQuack's old friend from Duckburg as both identities although more as Gizmo Duck than himself.
The Gizmo Duck suit itself balances on one tire and is capable of producing any kind of device that a cartoon could possibly produce. Gizmo Duck appears as a rival superhero for Darkwing Duck.
