THE BIG FEAT OF SCROOGE MC DUCK

The comic that tells the origin of Scrooge Mc Duck is the Duck Dinasty.

Scrooge Mc Duck was born in Scotland. He had two sisters, Ortensia and Matilda. In the hills his family was arch enemy with the clan of Whiskervilles. Little Scrooge begins as a shoeblack, and the first pay he gets is an american dollar. Nothing, to a Scottish. So, he understands that the world is though, well, he'll be tougher than the thoughests, and he'll always make his accounts balance.

At the age of thirteen he moves to America and joines one of his uncles (Angus) to pilot a steamboat on the Mississippi. Here he fights against his first enemy, a gambling man (cheater), Soapy Slick.

After, his life is a never ending travel: first to Texas (and here he becomes a herdsman under the name Buck Mc Duck), then Montana, after to Copper Hill. He returns home when it comes out of his knowledge that his mom is dead.

After a quick return, he becomes the 'Terror of Transvaal', where he meets Roosvelt. Then, he moves to the Australian Desert. Finally, he becomes and argonaut in the White Death Ditch, in Alaska, and founds the gold nugget which is called Duck-egg nugget for its big size.

At the end, he's the richest duck in the world, the most catankerous, though.
