Soul of Chogokin (SOC) (超合金魂, Chōgōkin Tamashii) 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, Leopardon from the Japanese TV adaptation of Spider-Man and Gipsy Danger from Pacific Rim.
