Smoke Dragon

About
As a child, Kaneki had all the same features he has now as an adult with black hair and black eyes. As a normal university student, Kaneki is a scrawny young man with little to no athletic background who prefers to read books. In his free time, he wears casual clothes.

At work, he wears the standard Anteiku waiter uniform, consisting of black trousers and a grey waistcoat over a white dress shirt, and a brown necktie. Because he couldn't properly control his single kakugan that manifests in his left eye, he wore a medical eye patch to cover it.

His ghoul mask shows resemblance to a leather gimp mask with an eye patch. It bares a lipless mouth that shows large, gnashing teeth, much like restrained asylum monster. The bolts sticking out of his neck and the fact that he is an artificial ghoul reminds a Frankenstein theme.

After being tortured by Yamori for a period of ten days, his hair became white and his nails turned black due to heavy stress, anxiety, and continuous bodily regeneration. This condition is known as Marie Antoinette syndrome. It is caused by extreme stress or emotional trauma like he had undergone. He also began wearing a form fitting black outfit when he had the intention of fighting as a ghoul, both for intimidation and practicality. Kaneki also becomes muscular and is shown to be a bit taller as well.

After the timeskip, his white hair is now adorned by black streaks which have grown out from the center of his head, and his nails are no longer black. Similar to the other Ghoul Investigators, Sasaki is seen well dressed in the standard suit and tie most of the time. When embarking on missions, he wears a white trench coat over his uniform and occasionally carries a briefcase with him.

After the events of the Auction Raid, as noted by Tsukiyama after their reunion, Haise's hair has begun to revert to it's original hair color prior to being tortured by Yamori. During Operation Mask, he re-donned his Eyepatch mask.

After the Tsukiyama Family Extermination Operation and regaining his memories, Kaneki's appearance has changed drastically. His hair has regained its original black colour and has grown out. He now wears a black trench coat with a design similar to the ones worn by the Arima Squad. His attire is accented by a pair of red gloves, and glasses. His current appearance distinctly resembles Kishou Arima.

In the oneshot, Kaneki's appearance is relatively the same, except has more muscular build, and instead of leather mask with an eyepatch, he wears a plan white mask with exaggerated teeth and lips with one eye in the form of a plus, and the other a heart. It strangely resembles a clown mask.
