Prince of Persia: The Two Thrones is an action-adventure game developed and published by Ubisoft Montreal. It was released in December 2005 for the Xbox, PC, PlayStation 2 and the GameCube. In the game the Prince develops a split personality, known as the Dark Prince, and this alter-ego constantly bickers with him in his mind about right and wrong. At times, the Prince physically transforms into the Dark Prince. [Info from Wikipedia]
As noticed by Zapages from the NeoGAF Forum, initially the Dark Prince had a different design than the one in the final version. Check the videos below for a comparison:
