Mark of Differentiation
The Mark of Differentiation is an identification system required by law for Different individuals. It is composed of a large black tattoo of the letter "D." Inside the "D" is the name of the Different, their Ability Description, and their Threat Level Designation. Individuals who go through evaluation and testing by Section 26 receive the Mark of Differentiation upon their release from the program.
The system was developed by Section 26 as part of the Different Acts of 1986. The Acts required all Different individuals to identify themselves; simultaneously, law enforcement agencies around the nation needed a system to manage the varying threat levels of Different individuals. The Mark of Differentiation addressed both of these concerns. Law enforcement officials can easily identify Different individuals while also being provided with a brief rundown of the threat the Different individual might pose.
The requirement to receive the tattoo was challenged in court by Stephen Geiger. The law was ultimately upheld in the Supreme Court in the case United States v. Geiger.
