2007 marked the 25th anniversary of the "Real American Hero" line. To commemorate the event, Hasbro released a "25th Anniversary" collection of newly sculpted 4" figures (as opposed to the 3¾" scale of the RAH line) based on classic and new designs of many of the line's best known and most popular characters. The 25th Anniversary figures replaced the classic O-ring construction with a swivel chest feature and increased points of articulation beyond the standard shoulder, elbow and knees to swivel wrists, ankles and double-hinged knees.
