D12 (aka The Dirty Dozen and D-Twizzy) was initially formed in 1991 by Proof who invited local Detroit rappers such as Bizarre, Eminem and other members who would leave the crew before it achieved success including Eye Kyu, Killa Hawk and FuzZ. The group was a loose collective in the vein of Wu-Tang Clan. Several members began making names for themselves in hip hop during the late 1990s. Bizarre was named Inner City Entertainment's "Flava of the Week". He would also release an album entitled Attack Of The Weirdos and become a member of Tha Outsidaz with Eminem and Rah Digga.
