Shruikan is the name of his dragon :)
Eldunari (The Hearts of Dragons)
The evil king in Eragon is named King Galbatorix. He is the main antagonist in the book series and rules the land of Alagaësia with cruelty and fear.
Galbatorix's first dragon was Jarnunvosk.He was killed by urgals.
If you are talking about Eragon's dragons name it is Saphira. If you are just talking about the dragons in the series it is Thorn, Gladier and I dont quite remember Galbatorix's dragon's name.
Shruikan, against his will, is the name of Galbatorix's current dragon.
Eragon casts a spell (in his mind because he couldn't speak) to have Galbatorix experience all the pain and anguish that dragons and humans had felt since the oldest heart of hearts. The pain was overwhelming, so Galbatorix cast a spell that killed him(self).
Brisingr, the third book in the Inheritance Cycle by Christopher Paolini, sees the protagonist, Eragon, continue his quest to defeat the ruthless king, Galbatorix. The resolution involves a final battle between Eragon and Galbatorix, during which Eragon discovers a way to defeat the king using his true name and the Eldunarí. After a fierce confrontation, Eragon emerges victorious, bringing an end to Galbatorix's tyrannical rule.
Nobody plays Galbatorix in the books. It is a book. The character in the books is the main protagonist; the evil king that had taken the throne by force at the fall of the Riders.
Originally he was a dragon rider. After his dragon died & the elders refused to give him a new one, he stole an egg, raised the dragon to be evil then hunted down & killed all riders dragons who refused to ally themselves with him. He then declared himself king over Alagasea.
In the book Eragon, the only dragons mentioned were Shruikandor (Galbatorix's dragon) and Saphira (Eragon's dragon). However, if that doesn't answer your question and you're really asking why Christopher Paolini wrote 3 dragons into the Inheritance series, then that's a pretty dumb question...
