This is the 50th Anniversary Soul of chogokin Mazinger Z from the 1st episode of Mazinger Z.
Mazinger Z is sold separately but the two mechanical beasts K7 and M2 are sold as a set for the 50th anniversary package.
If you love Mazinger Z then this is a MUST have for your collection. Mazinger Z is very articulated compared to the old SOC Mazinger Z.
The only missing is the base stand.
