Juuzou Suzuya

As a child, Suzuya's personality was somewhat normal, albeit a tad twisted, but as a result of Big Madam's treatment, he no longer felt fear, pain, nor did he have any morals. Yukinori Shinohara, his mentor, described him as a "problem child". Despite his childish and playful demeanor, he was also extremely violent and highly disturbed. He usually described his killing methods to be clean, without needless movements, which is a skill he seemed to take pride in. He shows no hesitation to kill someone. He even goes as far as to consider it a part of daily life, and lacks awareness of death's weight. Due to his past, he was blamed for the killings of multiple animals done by Goumasa Tokage and Tooru Mutsuki during his time being trained by the CCG, even though he was innocent. Suzuya was used as the scapegoat since nobody doubted he had committed the killings, which averted suspicions from the culprits who were truly responsible. Suzuya is generally distrusting of people who write him off as a problem child - he notices and hates people looking at him with certain "eyes," judging him. Because of his lack of emotional understanding, he was willing to confront any opponent head-on, no matter how dangerous they were. This had proven to be disastrous when he decided to take on the Owl alone when cooperation was necessary. Originally, he showed no signs of empathy whatsoever and did not understand the emotions of others. However, when he realized how important Shinohara was to him, he let out a cry of anguish. This demonstrated Suzuya's capability to love and care for individuals close to him. After Shinohara was comatose, Suzuya expressed guilt and remorse for not being able to protect him, deeply bowing and apologizing to his wife, and he also kisses Shinohara on the forehead. After the timeskip, Suzuya has matured considerably, becoming more calm and warm towards others. Although he still retains some of his childish traits such as bringing candy into serious meetings, he has become a capable mentor and leader, commanding his own team of investigators. He is now somewhat capable of understanding the predicaments and emotions of others, giving sound advice to Tooru Mutsuki after the latter expressed his fear of fighting. Juuzou has become much more dedicated to the CCG, which is evident when he told Big Madam that he was going to kill her, not because of a personal grudge, but rather it was simply his job to exterminate ghouls. Despite his slight change of character, he is still quite ruthless to ghouls.

Suzuya is a young man with an androgynous appearance, characterized by fair skin and pristine shoulder-length white hair. Adorning his hair are red hairpins arranged in the shape of the Roman numeral XIII (13), neatly taming his bangs. His eyes, a deep shade of red, are marked by noticeable bags underneath. He self-stitches his own body, explaining it to be a form of body modification. A miniature set of red threads that appeared to be two x's are stitched on below his right eye. One below his bottom lip and a line of several stitching threads from his upper neck downward, and several more around his right arm and hand. His attire consisted of a white suit with sleeves rolled up to the elbows, left halfway buttoned and polka-dotted red suspenders that supported his black pants and a pair of red slippers. He frequently wore a black suit above all this, with rolled up sleeves. In the Joker side story and at the start of Tokyo Ghoul:re, Suzuya's appearance changes drastically. His hair is now dyed black and reaches only chin-length. And, his stitches are in a different pattern. His attire consists of a black suit with black dress pant and red suspenders with yellow triangle pattern. He has a prosthetic leg as replacement for his leg that was maimed in the Owl Suppression Operation years ago. Later on in Tokyo Ghoul:re, Suzuya's hair has now reached passed shoulder-length once more. He either keeps it tied in a bun above his head or in a ponytail, or without, as was shown in the promotion ceremony. He has also changed the stitch markings below his right eye, returning it to the original two x's. He has removed all stitch markings from below his right lip. He also changed the Roman numeral in his hair, now making it the Roman numeral XX (20), the "Judgement" tarot.

Suzuya possesses amazing physical abilities, allowing him to easily match most ghouls in combat. His physical abilities are so impressive that CCG personal claimed that he doesn't even need to attend the Academy and can enter active duty immediately, even though he was just a teenager. Superhuman Strength: Suzuya's strength substentially belies his slight build; he is strong enough to easily handle the large 13's (Juuzou's) Jason quinque, even while also carrying the entire Scorpion 1/56 set. Superhuman Speed: Suzuya is incredibly fast and nimble, able to move literally faster than the eye can see; in fact, even most ghouls can't keep up with him in combat. During CCG operations, he was often shown swiftly slaughtering multiple ghouls. Superhuman Agility: Similarly to ghouls, Suzuya can easily jump very high and manouver on narrow surfaces. During combat, he often employs flips and other impressive acrobatic feats. Pain Tolerance: Due to Big Madam's treatment, Suzuya became practically numb to pain. During his time with Big Madam, Suzuya could handle hooks going through the back of his body. After getting his stomach cut open, Suzuya could still fight and beat Kurona and Nashiro without any difficulties. Suzuya was still able to consistently fight the One-Eyed Owl after he had lost a leg. Swordsmanship: Being able to use his quinque to destructive abilities, Suzuya can use the strength of his attacks to efficiently subdue ghouls and even slice off one of the Owl's arms. * Scorpion 1/56: A bikaku quinque that takes the form of a flat-headed switchblade. Having great skill with the blade, Suzuya can quickly pinpoint a throwing knife and easily execute ghouls. These quinques are simple yet effective. * '''13's (Juuzou's) Jason''': A rinkaku quinque that takes the form of a scythe with a jagged and squared blade. When using this blade, Suzuya can easily slice through multiple ghouls and use the gimmick to pierce a half-kakuja ghoul. The quinque had been damaged by Kurona's kakuja but later repaired and used to defend the 19th Ward Branch Office against the ghoul attack. Arata Joker: A koukaku kakuja quinque that is capable of attaching itself to the user and be used as an armor. It enhances the user's speed and allowed Suzuya to ambush his targets so quickly, his target could not keep up with his movements. This armor also has a claw function that was capable of bisecting an SS-rated ghoul with relative ease. Like the previous Arata quinque, it consumes the user, as it caused Suzuya to bleed heavily. Submachine gun: During the 11th Ward Battle, Suzuya was armed with a submachine gun that resembled a MAC-11. When charging the base, he used the weapon to slaughter every ghoul inside. Prosthesis: Since losing his right leg below the knee in the battle against the Owl, Suzuya has been fitted with an advanced prosthetic leg. He can detach his prosthetic leg and attack non-expecting ghouls with the blades hidden inside.
