Soul of Chogokin(超合金魂,Chōgōkin Damashii) or "Soul of Super-alloy", is a popular line of adult collector's toys produced by the Japanese company Bandai.
The line, which began in 1997, focuses almost exclusively on mecha (robots) taken from various 1970s and 1980s anime series, although the line has diverged from this on a number of occasions, most notably the release of several mecha from the mid-1990s anime Neon Genesis Evangelion. More recently, the line has expanded further to include 1970s mecha from Super Sentai and other tokusatsu series, such as the Battle Fever Robo from Battle Fever J and Leopardon from the Japanese TV adaptation of Spider-Man. In 2017, Bandai will be releasing yet another Super Sentai mecha Daizyujin from Kyōryū Sentai Zyuranger which happens to be the first Super Sentai series adapted for American audience under the name Power Rangers as the first season of Mighty Morphin Power Rangers. This would mark the first Power Rangers Megazord to be given the Soul of Chogokin treatment. Also in April 2017, a prototype for an SOC figure for the robot Gypsy Danger from the 2013 film Pacific Rim was unveiled.
