"Great...We have to fight an old...no...Ancient brain-in-a-jar cyborg...what will the Multiverse send our way next?..."
-Samuel Eastmen talking about Vioo'luuk
Tuzil'zuuk Vioo'luuk, also known as "The High General" by gamma gems under his command and "Sir Brain-in-a-jar" by Samuel Eastmen, is an ancient cyborg who fought for the First Human Empire during the Second Human Civil War. Noted for his 'grim reaper/skelentor'-like appearance, he was a treat so powerful that the crystial gems and Homeworld gems were forced to work together to stop him. He's regarded as a sad fact of life in that he did not know of the Empire's destruction and attacked because he believe that he's "restoring order" and still fighting a long sense ended civil war.
