The great and powerful Mandalore the Indomitable. He weilds his mighty battle axe as he aids Ulic Qel-Droma in battle, as seen in Star Wars: Tales of the Jedi -- The Sith War. Definetely a rare custom minifigure.
Do you mean Mandalor the Indomitable? If so, than he should actually be dressed in orange, not red. Granted finding that many orange parts is a pain, so paint might be easier. While you're at it, you might want to paint the circular portion of his mask. If memory serves, the curved edge of hte axe should be on the top of the pole rather than set like that of a normal axe.
