Generation 2
Rook was one of the countless second generation Transformers serving under Jhiaxus on the Twilight.
After contact was made with the first generation Autobots, Rook was thoroughly puzzled by his ancestors' war, not understanding the difference between "Autobot" and "Decepticon"; Jhiaxus merely assured him that, whatever they were called, they were nothing more than evolutionary throwbacks. War Without End!

As the war against their predecessors continued, Rook noticed that the stress was beginning to tell on Jhiaxus. Primal Fear! He continued to observe and worry as his commander's ice-cold demeanor of control and amoral objectivity continued slipping and he began reverting back to the mad tyrant he once was. New Dawn He continued to act as Jhiaxus's aide-de-camp during the battle on Earth. Total War!

At some point after this, he apparently abandoned his post, as he was next seen reporting in person to the Liege Maximo at the Hub. A Rage in Heaven!
