Brushogun was an amazing artist during his youth, and soon fell in love with the image of a woman he had painted. Brushogun used a dark magic spell to bring his creation to life, but unfortunately, the spell came at a terrible price. It cursed his body, and transforms him into a paper-skinned, ink-filled being, Brushogun. He could create ink minions in a variety of colors when drawing with this magical ink. Using his powers, Brushogun was responsible for various criminal outbreaks in Tokyo, but was eventually caught by the authorities.
The Titans came into conflict with Brushogun when his creation Saico-Tek attacked Jump City and the Titans Tower. Determined to solve the mystery behind the attack, Robin and the other Titans travel to Tokyo, where they meet more creations of Brushogun but are popularly assured - particularly by Commander Uehara Daizo of the Tokyo Troopers - that Brushogun is merely an urban myth. However, shortly the Titans find themselves under attack from more of Brushogun's creations - among them another Saico-Tek, Nya-Nya, and Mecha-Boi and are framed as enemies of the state, making them hunted fugitives.
Finally they manage to backtrack Brushogun to a closed manga publishing house, only to find out that Brushogun is a victim himself: He has long been imprisoned by Daizo and hooked up to a giant printing press to produce more villains for Daizo to fight, so he would be worshipped as a hero; the Tokyo Troopers are also Brushogun's creations. The first Saico-Tek and various helping hands lent to Robin were actually Brushogun's calls for help to prompt the Titans into finding and freeing him.
Revealing himself as the villain he really is, Daizo orders the living ink creations to attack the Titans, but these are soon overwhelmed by the Titans; as a result Daizo chooses to merge with Brushogun, mutating into a giant ink monster. Robin defeats the monster by pulling Brushogun out of it, causing the ink creature to revert back to Daizo. Finally released, Brushogun peacefully dies in Robin's arms, fading into nothingness. After the well-fought battle, Robin and Starfire share their first true love's kiss.
Brushogun's appearence resembles that of Venom or Slenderman when he first turned into Brushogun. When he was a regular human, he was dressed in a traditional Japanese kimono with a black sash and having dark eyes and black hair in a ponytail. In Modern day, he has become an old man with light gray skin, a couple strands of hair, dark eyes and a lot of wrinkles. The only clothing on him at the time is a pair of black briefs, most likely created when he exited out of Daiso's monstrous form.
The dark spell he cast has cursed his human form. He is forever transformed into a magical, paper-skinned being that can generate supernatural ink from his body. When painting with this ink, it can perform magical effects.
Brushogun mainly uses the ink to draw creatures and objects that are instantly brought to life, which have functions and powers of their own he specifically made for them and can regenerate from any damage, including lost limbs. Because they are made of ink, his creations all have a fatal weakness to water. When his ink is written on a piece of paper, it can be enchanted to fly toward a desired location, and the ink itself can be materialized into special objects to be used at that time, like how it became an exploding shuriken to help Robin escape from the police van.
Whne pushed to his limit, Brushogun can become a giant monster made of living, supernatural ink that he has physically generated from his body. In that form, he can create dozens of creatures at once, and supernaturally possess and absorb any machines connected to him at the time.
