Inventions and Technology

The World of D-Gray Man is full of technological devices designed for many purposes. Most of them are the result of the Black Order's research, specifically the scientific section.

Golems
Golems are small, often portable, multi-purpose devices, typically featuring communication abilities. The creation of some of them seem to be both thanks to Technology and Magic.

Robots
Robots are talking, often human-like artificial devices. They are charged with typical tasks by their masters and are able to function by themselves.
 * Komlin : A series of robots created by Komui Lee
 * 65: A ghost-like robot created by the scientific division
 * The Gatekeepers : A series of robots designed to watch the entry of the European Branch of the Black Order.
 * Dolls: The Town of Mateel used to create dolls who dance and sing. Lala was one of them.

Substances
Some liquids or gases may have particular, or even unexpected effects serving diverse uses.
 * The Komuvitan D: A substance originally created by Komui in order to do without sleep and make people work more. High dose transforms the subject in an angry zombie eager to spread the Virus.
 * Memory Eraser Medecine: A potion used by the Black order to erase all the memories of the Order of those who quit it.
 * Knock-out Gaz: A potent gaz that makes you feel asleep without 3 second of inhalations.

Items
Prehensile, portable technologies which need to be effectively used by someone.
 * Wireless Handcuffs: High-tech handcuffs that allow one prisonner close from another person of place. If one of the 2 handcuffs detects escape thought or if the 2 handcuffs get 20 meters far from each others it will send a high voltage shock to both handcuffed people/thing. A creation of the European Branch's science section.
 * Talismans: alismans, seen in several forms (including but not limited to lamps, round shields and heavy duty ballistic shields), are devices that work using unknown mechanisms to form cubed barriers of light that block/contain Akuma. Use is not indefinite; talismans run on battery power that will run out after extended use. They are many used by Finders.
 * Phones: Finders have been seen carrying ahead of their time corded telephones.
