Doofus Drake is a friend of Huey, Dewey and Louie who appears in DuckTales and earlier Junior Woodchucks comics. He is somewhat larger, likely due to being older as well as having a constant appetite. He appears often with Launchpad McQuack, acting as his sidekick. Doofus is a member of the Junior Woodchucks, who is often shown wearing his uniform.
Doofus was voiced by Brian Cummings.
Doofus is a rather dim-witted and clumsy character with a positive attitude that is just as insatiable as his appetite. He exhibits hero worship for Launchpad, which frequently borders on the delusional (the relationship between Doofus and Launchpad, in many ways, mirrors that of Launchpad and Scrooge). Doofus is also marked by his strong moral compass, best demonstrated in the episode "Superdoo!", in which he uses paranormal powers to save the Junior Woodchucks from catastrophe, only to voluntarily relinquish them for the sake of hard work and friendship.
When Scrooge travels 40 years into the future in the episode "Duck to the Future", Doofus has become trimmer and it's revealed that he is married to Webby . Since this future also involved Scrooge's nephews becoming money-grubbers and Magica De Spell ruling the world, this may not be definite.
