Screw loose

Who is he? Vint is a rooster inventor. He works for Scrooge McDuck, creating various devices for him. Vint also has a family tradition: his father, Felton, and grandfather, Ratchet, were also inventors.
Vint is a man of ideas. When he needs to quickly come up with something for a specific purpose, he hits himself on the head with a small wooden hammer—and almost immediately, inspiration strikes. His inventions often don't work as intended: the device might do something completely different from what was intended. But in the end, many of them prove very useful—that's how Vint helps his friends get out of difficult situations.
Vint continues to actively experiment, for example, creating the Duckbot (also known as Techno-Duck), a device that acts as Scrooge's bodyguard. In other stories, he invents other gadgets, including a super-megawatt satellite dish (which ultimately helps establish contact with aliens) and a Techno-Duck suit for enhanced security of Scrooge's money.
