Eureka!

Edi is the Gyro Gearloose's little helper.

His name stays for 'Edison', the inventor of lightbulb

Gyro Gearloose is an inventor, a fictional character, an anthropomorphic chicken created by Carl Barks for the Walt Disney Company. He is part of the Scrooge McDuck universe, appearing in comic book stories as a friend of Donald Duck, Scrooge and anyone who is associated with them.

Edi, called Little Helper in English, is a small, humanoid robot constructed from pieces of metal and a lightbulb, which serves as his head. He acts as the assistant to Gyro.

In the Donald Duck comics, he is often shown as an inventor himself, sometimes copying Gyro's inventions.

Edi never speaks, but occasionally uses thought bubbles. He enjoys helping Gyro clean up the unusual consequences of his inventions.
