This GT-01 is a "small-sized Chogokin Soul" figure released by Bandai in 2003. Compared to traditional Chogokin Soul figures, it's smaller, more affordable, and primarily targeted at nostalgic collectors, making it a popular entry-level model for many. The copyright information engraved on the feet is an important identifier of genuine Bandai toys and a key factor in distinguishing used Popy figures from modern reissues. The " Go Nagai・Toei Animation" inscription on the feet further confirms that it's an officially licensed Mazinger Z toy.
