Rago

Rago (Japanese: ラゴゥ, Ragou) was the main antagonist of Beyblade: Metal Fury.

Known as the Child of Nemesis, he was partly responsible for the Nemesis Crisis that almost plummeted the world into destruction. He was largely known as the owner of the destructive and almighty, Diablo Nemesis X:D as well as a Legendary Blader who fought against the others.

Upon transforming into Nemesis, the Legendary Blader of autumn and No. 1 Blader in the World, Gingka Hagane with his Beyblade, Cosmic Pegasus F:D ultimately destroyed him and plummeted him into a bottomless pit hidden by darkness. As a result, he was declared deceased and the Nemesis Crisis ended at last.

Personality
Rago was a very fierce, ruthless, sadistic, evil and cruel person. He did not doubt himself and was always confident in Nemesis being its former keeper. He was not kind nor nice, as he did not contain any compassion or comfort. This was evident when he made a smirk as he watched Doji cruelly criticizing Ryuga for helping Nemesis' revival. He also seems to enjoy calling his enemies worms.

It seems as that the only person Rago truly cares about is Nemesis, as he is willing to commit to extreme lengths that it may take to conquer the entire world. Rago is also so powerful that it seemed hopeless for the Legendary Bladers to defeat him, especially since he was one of them.
