RIOBOT Grendizer and Spazer by Sentinel

Sentinel co. have revealed their take on ’70s super robot Grendizer as part of the stylized RIOBOT line, with a bit of added surprise.

Grendizer is available alone or in a set with the Spazer, a large flying saucer accessory. In this version, the Spazer can also be reconfigured as some form of armor with a giant pair of arms to provide Grendizer with a super mode of sorts.
Both releases have a projected release date of January 2019.

For discussion, there’s a Japanese Collectibles thread on the forums, though the Discord server is also an option.
