The Mississippi Aryan Brotherhood is a large racist prison gang based in the Mississippi state prison system. Despite the similarity of its name, it has no connection to the "original" Aryan Brotherhood, based in California and the federal prison systems. The logo of the Mississippi Aryan Brotherhood consists of a highly-stylized rendition of a combined A and B.
The New Black Panther Party for Self Defense (not related to the original Black Panther Party) is the most extreme organized racist and anti-Semitic African-American group in the United States. Its symbol consists of a leaping panther (an image appropriated from the original Black Panthers) superimposed over the continent of Africa.
The "Northwest American Republic" is a fictional construct created by Harold Covington, a long-time fringe figure in the neo-Nazi movement.

The Oklahoma Aryan Brotherhood is one of several white supremacist prison gangs in the Oklahoma prison system whose name derives from the unrelated "original" Aryan Brotherhood, which is based in the California and federal prison systems. Its patch is a shield on top of two lightning bolts and a sword, with a clover, a swastika, and SS bolts inside the shield.
Public Enemy Number 1 is a large white supremacist gang based in the prisons and on the streets of California. Its most common symbol is simply a shortened version of its own name, such as PENI or PEN1. Members may also refer to the gang as the Peni Death Squad or PDS, thus PDS is also a common tattoo.
Sadistic Souls is a small white supremacist outlaw biker gang active primarily in the Midwest. It is also a faction of the neo-Nazi group Aryan Nations. Sadistic Souls members may sport Aryan Nations symbology, as well as biker jackets and rockers that depict a Totenkopf image and the group's name, with the first "S" in each word of its name rendered as lightning bolts.
