Dyabolic, also known as Dydra Kaiser Zastec, is a Private First Class in the Vaktovian Empire. He joined the Vaktovian Ascension Core on January 4, 2015 and graduated just over two months after his acceptance on March 14, 2015.

Dyabolic's brother-in-arms is a Private by the name of Zynamic. One of the few very important people that he looks up to. Some of the few are Colonel ImAwesomeFoo and Sergeant Fourpapa1. Dyabolic has learned so much because of these two, and he gives them respectable credit for how far he has gotten. ImAwesomeFoo picked him up when he was just a Stage 3, and put him under his wing as his apprentice. Although Dyabolic had very low self-esteem at the time, Colonel IAF helped him use his potential and expanded his knowledge of the Empire. Fourpapa1 was his mentor during the 5th stage of his time in the Core, and although he failed him the first time, it encouraged Dyabolic to try harder and improve with practice. Since then they have been good friends, and also to this day Dyabolic remains IAF's Vaktovian Apprentice. Dyabolic claims, "I attribute all my success in my Vaktovian Ascension career to the moral and intellectual education I recieved from these men".

A quote that Dyabolic has on his profile: "I am loyal to only one flag. It is the same flag that only the greatest of men have grasped within their hands. It is the same flag that leaves you petrified if you dare announce it's name. Death to the Horde, and Glory to Vaktovia!"
