Released in 2006, Akuma was released as a part of Round 4, or the fourth series of SOTA Toys original Street Fighter action figure line.  This is for the White Akuma variant.  (Each character had 3-4 color variations, apart from their original Player 1 / P1 coloring.) 

This figure, while opened, is in great condition.  I acquired it from an avid Street Fighter collector in a large SOTA Toys lot over 15 years ago.  It was never displayed by me and just stored away from the light in a box for the last 15 years.   

*Note: The item you are purchasing is the exact one pictured here, so please look at the pictures carefully for questions on condition.  I've taken close ups / additional pictures of any notable scratches/damage I saw while taking pictures of the item.
