Jiu Dae-Gak

"'If I'm guilty of a sin... it'd be that I'm too strong.' - Jiu Dae-Gak"Jiu Dae-Gak is the father of Jiu Ji-tae and Jiu Ji-Hyun. He is a significant background presence in the story of Fight Class 3 and is the main antagonist.

Appearance
Jiu Dae-Gak is a tall, powerfully built man with dark eyebrows. He has close cropped hair and has a tattoo of his dead wife, Jiu Jin-Hee, on his right shoulder. Sometimes he is shown clean shaven, at other times he has a pencil moustache.

Background
27 years before the start of the story, Jiu Dae-Gak was a prodigy martial artist who had won many competitions, always placing top three in any competition he was in. However, his opponents often ended up gravely wounded, and when Dae-Gak was completely unrepentant about the death of Wang Won-Pyo during their match he was barred from professional competition by Korean sanctioning bodies.

Jiu Dae-Gak would then leave Korea for Brazil. He would under Wallid Barboza be taught in the art of Barborado Jiu-Jitsu, the only non-member of the Barboza family to be permitted to do so. Later, Dae-Gak would wipe out the entirety of Barboza's family including Wallid himself, with the sole exception of the young girl who would later become known as Maria Dacascos.

At some point, Jiu Dae-Gak became involved with the hosting of Vale Tudo in Korea, a barbaric no-holds-barred combat sport. It is likely that he is using Fight Class 3 as a front for this operation.

Plot
Jiu Dae-Gak would interrupt the funeral of his wife, Jiu Jin-Hee, in order to abduct his own daughter, Jiu Ji-Hyun. His young son, Jiu Ji-Tae attempted to stop this but Dae-Gak mocked his weakness and knocked him unconscious, scarring him for life both physically and mentally before absconding with Ji-Hyun.

Abilities
Jiu Dae-Gak is an exceedingly dangerous fighter. He possesses the same genetic weapons his son has: kinetic vision that allows him to see and avoid attacks, a flexible double-jointed body, and his "devil's gift", the ability to copy and memorise techniques after only seeing them. These traits were so impressive that Wallid Barboza even broke his vow of only teaching Barborado Jiu-Jitsu to other members of his family in order to instruct Dae-Gak.

It is unknown what Dae-Gak's preferred fighting methods are beyond having a knowledge of Barborado Jiu-Jitsu.

Personality
Dae-Gak appears to be both brutal and ruthless. His violent actions have lead to many deaths and injuries, and he was expelled from professional fighting by Korean authorities because he sought to kill his opponents in matches. He appears to despise weakness most of all.
