Little Helper

Little Helper, or simply Helper, debuted in the story "The Cat Box" in Uncle Scrooge #15 (September 1956). Helper is a small, humanoid robot (about 20 cm tall), constructed from pieces of metal and a lightbulb, which serves as his head. He acts as the assistant to the inventor Gyro Gearloose. In the Donald Duck comics, he is often shown as an inventor himself, sometimes copying Gyro's inventions.

Little Helper never speaks, but occasionally uses thought bubbles. He enjoys chasing mice and helping Gyro clean up the unusual consequences of his inventions.

Helper's origin is given in the story "Gyro's First invention" (written by Don Rosa), which appears in Uncle Scrooge #324 (December 2003) as part of Gyro's 50th anniversary. In this retelling, Gyro accidentally passed on some of his intelligence to Donald Duck's desk lamp. Gyro added small metal arms and legs to the lamp, so that it could move about. Little Helper lived up to his name, helping his creator with his inventions.

In the Italian comics, his name is Edi, in reference to Thomas Edison.

Little Helper appears alongside Gyro in the animated series DuckTales. He is called Little Bulb in the series, which is compatible with the Brazilian name for the character - Lampadinha - informal diminutive of Lâmpada (lamp), in Portuguese.
