Rudy

"'Those who serve the light.'"Orphaned by the war, Rudy dreamed of becoming a knight after he got adopted by the last 'Knight of Light'. He and Kris were best friends and rivals to each other, competing for the honor of being the next 'Knight of Light'. But one day, Kris got tricked by Dellons and became inelligible for the title. Rudy feels a great responsibility and pressure after becoming one of the Seven Knights and is always pushing himself the hardest he can.

Season 1
Rudy is an orphan from the continent of Asgar who was granted the power of Destruction. As he competed with his friend and rival, Kris, for the position on the Throne of Light, they were tricked by Dellons into fighting against each other, with Kris suspecting Rudy of killing his knights and Rudy forced to go after Kris who had became a "criminal". After being defeated by Kris, however, his life was spared, showing that they actually still care for each other. Kris later went back to hell territory, and Rudy back to Terra. Rudy then asked Evan's help to settle the misunderstandings amongst the seven knights.

After finding out the truth about the conflicts Dellons caused, Rudy sent Evan and his group to Aisha continent to chase after Dellons. They found out that Dellons was helped by the Emperor of Aisha, Pascal, and the Four Lords who followed the Emperor's orders. The Seven Knights fought the Four Lords and the Emperor, who was misusing the power of Destruction, and lost track of Dellons.

Season 2
The Seven Knights found out that Karin was the descendant of God of Destruction. Arriving into the decision that they should kill Karin in order to prevent the destruction of the world, the Seven Knights chased after Dellons. Evan appeared to fight them, but was defeated by Spike. In the mean time, Dellons had managed to awakened his power and defeated Rudy and Kris. Dellons then escaped, taking Karin with him.
