Galbatorix stole Shruikan from one of the original Dragon Riders named Kialandi. Kialandi was forced to give up Shruikan after he was persuaded by Galbatorix through deceit and manipulation.
He is black.
Shruikan is the name of his dragon :)
His name is Shruikan and he's Galbatorix's partner.
His first dragon was killed by Urgals. Shruikan, his second dragon he forced to serve him, is still with him.

From what I know, the only dragon alive are Thorn, Shruikan and Saphira (Glaedr doesn't count because he dies in Brisingr, and neither does the green dragon because it hasn't hatched yet).
Galbatorix's first dragon was Jarnunvosk.He was killed by urgals.
appearing dragonriders are: Eragon - Saphira Brom (dragon died before book 1) - Saphira Murtagh - Thorn Oromis - Glaedr Galbatorix - Shruikan there are also some others mentioned, like the Eragon, that Eragon was named after, but these are the ones that actually appear. you´re welcome :)
