—Timothy to Komui after askimg him to pay various overly expansive depenses
AppearanceTimothy is a boy of average weight and height.
He has a blue mullet-like (short hair at the front and sides and long at the back) haircut and brown eyes. His hair was originally brown, but turned blue when he awakened Tsukikami. At the orphanage he wore rather normal clothing consisting of a large striped bandana (to cover his innocence), an orange baggy shirt, brown cropped pants, a blue choker around his neck and pointy slippers.
His exorcist uniform is different from what older exorcists wear. Although the jacket isn't modified the rest of his uniform has been changed. He wears shorts, pads and roller-skates instead of regular clothing
Timothy's spirit (when he ejects it out of his body) has his hair in the shape of cat ears.
Timothy acts like a boy his age should – he is immature, childish and hates studying. It's easy to throw him off balance and when confronted with a problem he finds hard to deal with (in both physical and mental way) he either throws a tantrum or starts to cry uncontrollably.
At first he seems to be arrogant and greedy, but it’s a false appearance. He really cares for people he loves or admires and tries to help them. Unfortunately, his young age and lack of experience often cause him to be more of a hindrance than a help.
Although not all of his actions are of pure, free will, after joining the Black Order he forces Komui Lee to pay for all the items he stole.
Timothy was born and raised in Paris, his father a minor jewel thief who was chased by inspector Galmar (Emilia's father).
During one heist, the fear of getting caught was so strong that his father forced young Timothy to swallow a stolen jewel. However during a raid set up by Galmar his father was caught and imprisoned.
Emilia tried to convince the inspector to adopt Timothy, but Galmar refused, feeling guilty for the commotion he made during the raid
Instead, he decided to leave Timothy in Hearst Orphanage, but not before consulting with a doctor about the jewel. It was revealed that it was impossible to remove the jewel from Timothy's forehead, which made his hatred toward his father grow even more
Two years after his arrival at the orphanage, Timothy discovered his ability to possess people. He never used his power though, because he knew that there was no need However, after discovering the orphanage's financial problems, he decided to use his ability to make money by resorting to theft.
Phantom Thief G Arc
When Thief G first appears, he leaps from a window and is immediately captured, despite claiming that he will never be caught.
Thief G's crimes take place at the Louvre in Paris, where he intends to steal an expensive crown. The exorcists lay in wait for him, and Yu Kanda immediately defeats him. The crown is handed to a police officer, who is then controlled by the phantom and turns into Thief G. When Allen and Link ambush the new Thief, he throws the crown, and possesses Link. The thief is able to use all of Link's abilities and weapons, and has excellent control over them.
The thief laughs at the officer who was reprimanded as G, Allen's accusations angers the thief who fights back, but is, again, easily defeated. He is pierced by Allen's sword and threw a tantrum, sobbing uncontrollably. He leaves Link's body, and is tracked down to the orphanage by Noise Marie, to whom his cries are easily recognizable.
Timothy at the Orphanage
Timothy is shown for the second time (the first time being his perverted attack on Emilia) at the orphanage. Emilia tries to make him study, and he retaliates by running, then grabbing her chest. She kicks him through the door into Allen Walker, whom he possesses. Walker's 'odd behaviour' alert the rest of the group, the truth is revealed and Timothy is caught red-handed.
As Mother Superior tells the Exorcists about Timothy's past, which confirms their supposition of boy being a Innocence's user, the skulls erect a barrier around the orphanage and sends Level 4 Akuma.
Fighting the Akuma
While Allen, Kanda, and Marie fight the Level 4 Akuma, Timothy and Link meet two Level 2 Akuma, and one Level 3 Akuma, who have been turning the humans to dolls and hunting down the innocence. Mother Superior is turned into a doll by the Level 2, and Emilia is shot by one of the nuns who work at the orphanage, but secretly helps the Earl. The broker is turned into a doll, and the Level 2 captures Timothy. Link tries to seal the level 2, but is ambushed by more Akuma, and is turned into a doll as well.
When Emilia tries to free Timothy and the Akuma approach her, Timothy takes control of the Level 2 Akuma that has turned humans into doll, releasing and activating "Divine Possession" for the first time. His innocence takes a human form, and helps teach Timothy how to fight, and he defeats the other Level 2 Akuma. When he attempts to fight the level 3, he fails, so he attempts to possess the Level 3 instead. Again, he fails, since his innocence isn't developed to that level yet. When he goes back to possess the Level 2, he finds that it has been purified and disappeared. He flees back to his body, and is saved by Link, is was able to move after Timothy purified the Level 2 Akuma. Link's body starts to crack, but his innocence tells Timothy that he can't help Link by possessing him. The Level 3 goes to defeat Link, but a member of CROW comes in and absorbs the Akuma.
The Level 4 Akuma is defeated by Allen and Kanda, and Timothy is rescued. He shares a few last touching moments with Mother Superior, then joins the Black Order as an exorcist with Emilia who pledges to help in any way she can.
Timothy has become the new apprentice of Klaud Nine, much to the disappointment of Froi Tiedoll. Later that day is seen being tutored by Emilia - while their progress is supervised by Klaud Nine much to Timothy's dismay.Timothy quickly got along with everyone upon joining the order. 
Artificial Exorcists Arc
He is last seen in Greece along side Klaud Nine, Lenalee Lee and Goushi. In the anime, he tries to protect Lenalee from the maddened Goushi after his transformation, but is defeated and knocked out.
Seeds Of Destruction arc
 After coming back to the Black Order headquarters he's seen as he attended the feast - along side with other Exorcists and Science division - prepared by Jerry. During the meal Tsukikami voiced out his confusion toward passing by Cardinal - but the Innocence wasn't sure about the feeling.
After Allen's escape Timothy takes part in the raid set to capture him. But he, along with the rest of the Exorcists, is stopped by Tewaku. In the anime, he notices the swarm of Akuma ment to hold them off and fights alongside the others agains them using his Innocence. When the Thirds (Madarao, Tokusa and Tewaku) broke through Miranda's defence, Timoty manages to shield her from the Flame Feather spells with his own body. Then, the Thirds confront them directly with even more Akuma, and Timothy is shocked by the Thirds' capability to absorb the attack even of his master Klaud Nine. Timothy then is seen within the barrier of Miranda's Time Out while Klaud, Sokaro and Krory continue to fend off the enemies, but soon enough hurries up to help Marie when he joins the battle.
Three months after the event, Timothy still serve the Order under Klaud Nine command. When the woman brings half-conscious boy to the hospital ward, after catching cold in Bilbao, he is shown to share the same sadness as others when Walker is mentioned. After losing his thirtiest chess game against Komui Lee, the latter offered him what he believed was his own Timcanpy to solace him but this was actually ...a Kom-Canpy...
Powers and Abilities
- Innocencification: Though a process called "Innocencification," Timothy can eject his spirit from his body and possess the bodies of Akuma. In order to do this, he has to first leave his body through the gem on his forehead, forcibly eject an Akuma's spirit from its body and then take the Akuma's spirit's place. Then, Tsukikami's "Second" devours the spirit of the Akuma. While possessing an Akuma, he can use any of the abilities that were inherent to that Akuma's body. Once Timothy leaves the body of an Akuma he has possessed, Tsukikami purifies it and it turns to ash.
- At his current level, Timothy can only possess Level 1 and Level 2 Akuma, though as he gains experience with each invocation of Tsukikami, he will eventually be able to possess more highly-leveled specimens.
- Tsukikami's "Second": A secondary being that came into existence when Timothy first properly possessed an Akuma, it acts as his guide, explaining the parameters of his Innocence to him and chastising him when he makes mistakes. Only Timothy can see and hear him. Tsukikami can also possess Timothy's main body whenever he is not occupying it.
Tsukikami's current form is based on an adult version of Timothy's own body, something Tsukikami has confirmed he purposefully did for the sake of convenient communication.
Tsukikami has a ghost-like shape of a tall man in the mid-twenties. He has the same haircut as his host – Timothy, but purple colored, pointy ears and white skin with navy-green markings: cross on the forehead (with the vertical line ending on the bridge of his nose), characteristic markings under the eyes and marked upper lip. His nails have the same color.
Tsukikami wears loose white kimono (with Japanese character in the front) fastened with stripped purple obi and blue-white thick rope. His pants have blue and white checker pattern. Tsukikami is barefoot.
Although his accommodator is his "master," he and Timothy treat each-other rather familiarly.
