Kaleesh/Legends

The Kaleesh are a race of aliens that look a lot like dinosaurs, but then walking like humans. They hail from the planet Kalee. Their planet is in war with the planet Huk and the inhabitants, also called Huks.

General Grievous is a Kaleesh, but he was mechanically modified. The Republic chose the side of the Huks in their war against the Kaleesh, and Count Dooku tried to trick Grievous into joining the Separatists. When Grievous refused, Dooku shot his shuttle down when he flew away. Separatist medics recovered Grievous's eyeballs, and most of his organs. They put the remaining organs in a robotic body. Grievous could split his arms into two arms, giving him the ability to be extremely deadly with both Lightsabers or Blasters.

He received Lightsaber training from Count Dooku.
