As part of the Gundam Sentinel series, the S Gundam Booster Unit-equipped model is now available in METAL ROBOT Spirits (Ka signature) with a new color scheme! 
 
The design of the S Gundam by Hajime Katoki is reproduced, and the coloring and die-casting create a sense of solidity. By attaching the included booster unit, the S Gundam Bst type is possible. In addition, as a bonus part, a joint that can turn the METAL ROBOT Spirits (Ka signature) <SIDE MS> Zeta Plus C1 into a Bst type is also included. This is a new look for the Zeta Plus.
