Vicious is 27 years old, though appears older due to his grey hair, the deep bags beneath his eyes, and a generally worn face. He is usually seen with his pet cormorant perched on his shoulder and his katana in hand. This gives him a slight resemblance to Goemon Ishikawa from Lupin III, just as Spike seems to be a homage to Lupin himself and Jet's beard and preference for firearms invokes Daisuke Jigen. Vicious is a tall and thin man with gray, untamed hair.

After Spike and Julia both disappear Vicious hunts for them as he continues to rise in power inside the Red Dragon Syndicate. Learning of a relationship between Spike and Julia, Vicious tells Julia that if she doesn't kill Spike that he will kill them both. Vicious killed Wang and declared himself the leader of the syndicate. When the Van decided to execute him, they were surprised to see that Vicious' men turned on them, freeing Vicious and killing the others. They imprisoned Vicious and sent teams to kill Julia and Spike. The Van were ready, having been tipped off by a fortune teller (or so Wang Long said). Įventually, Vicious finally made his move on the Van, taking a team to storm the Van's chamber. The bag of Red Eye exploded, forcing him to retreat to the syndicate ship. Vicious left him there, took the Red Eye, and escaped, firing on Gren's ship and Spike's, which had just arrived. Vicious escaped the explosion hidden in his suitcase with the payment and was saved by Lin again when he took a bullet for him. Vicious coldly answered his question of why he testified against him three years ago with the simple claim that there is nothing to believe in, including camaraderie. The deal was going according to plan until the person revealed himself to be Gren. Later, they were contacted by the seller and Vicious directed the person to the top of a skyscraper.

Lin saved Vicious by standing in front of him and shooting Spike, allowing them to escape. They first saw Spike, who was also drawn to the communication. Vicious and Lin went to the moon to meet the person. While it was unusual for someone to do that directly to him, The Van allowed it, sending Lin with him. Vicious received a request to sell Red Eye from someone named Julia on Callisto. However, he saw Spike left a grenade and ran, surviving. They fought, each wounding the other but Vicious was able to push Spike through a window. He watched Spike arrive and kill most of his men before advancing to him on the second floor. Allowing Faye to contact Spike to tell him where she is, Vicious waited in a cathedral with his men. Vicious knew that Spike would be after him and decided to trap Faye Valentine who would be looking for Mao's bounty. Vicious himself killed Mao, but not before smiling when Mao said he would never have done this if Spike were still there. His men waited until Mao watched Carlos' ship explode to burst in and kill Mao's men. He sabotaged Carlos' ship when he visited Mao's headquarters to explode on his return trip. Vicious gradually lost respect for Mao, and, when Mao intended to sign a truce with Carlos of the White Tiger Crime Syndicate, decided to take action. It is established that Vicious knows Julia by this point as he gives her music box to Gren, whom he testifies against for being a spy in the war's aftermath. This betrayal seemingly triggered their blood feud and possibly resulted in Vicious' enlistment in the War on Titan.

Spike decided to leave the syndicate and attempted to take Julia with him. Mao Yenrai took Vicious and Spike under his wing inside the Syndicate where they rise up the ranks. He also met and developed a relationship with Julia. By 2068, Vicious had become a strong member of the Red Dragon, along with Spike Spiegel. Much about his early life was not widely known.
