All selected by my. Two Face (Harvey Dent), Bane (Unknown name, Dorrance), The Joker (unknown), Ras'al Ghul and Scarecrow The Master Of Fear (Dr. Jonathan Crane).

I had some idea behind select this characters. On edges are characters betrayed by faith, they are just mad, ex workers of Gotham's Offices (justice department, arkham asylum), next two (Bane and Ras'al Ghul) are driven by darkness with simple idea of conquer The Batman. In the middle is The Great One, Master of Chaos - The Joker.
