Lee Sin

He has been seen in eye candy of game footage, in the second official trailer. He was canceled because monks found it offensive to their religion. It is possible that he was remade into Udyr The Animal Spirit. However, Riot Game Designer Guinsoo Rageblade hints that this is not the case. Hohums has confirmed that the Blind Monk and Udyr have no relation.

Guinsoo revealed Blind Monk's true name: Lee Sin
