Amakuni Kizin Great Might Gaine Toy Review: Genuinely Astonishing

This is arguably the most impressive Great Might Gaine Toy to date.

One of the more involved entries in the Brave saga is Brave Express Might Gaine, and we now finally have a toy worthy of its Great namesake.

Might Gaine was the fourth entry in the Brave saga and was a uniquely popular series. Set in an alternate timeline where the world ran out of oil in the ‘50s, we jump forward nearly a century to 2049, where trains are now the main mode of transport.

It’s here we are introduced to Maito Senpuuji, a billionaire teenager who was orphaned at a young age when both his parents were killed in a tragic shinkansen accident. However, Maito’s father bequeathed him a unique legacy: sentient trains that transform into robots.

Maito then pilots one of these robots, called Gaine, and teams up with other mecha to take down the real evil Nouvelle Tokyo City.

In short, Might Gaine is an anime that asks the age-old question of what if Batman were a Japanese teenager with an arsenal of sentient trains that transformed into robots.

Now, if this whole trains-into-mecha sounds familiar, that’s because Takara Tomy also made the much more recent Shinkalion, which features transforming robot shinkansens.

In any case, later on in Might Gaine, the titular mecha combines with Might Kaiser to form Great Might Gaine, and it’s this design that this new Amakuni Kizin toy recreates.

Now, while some of the Brave series have made it Westward, Might Gaine is still a Japan-only release. So, the main way people know of this series is from the Super Robot Wars games. Namely, Super Robot Wars V, X, and T, all of which feature Might Gaine, and subsequently Great Might Gaine.

If you are new to the Amakuni Kizin range, these are mecha toys that have a great deal of diecast in their construction, amazing detailing and sculpts, as well as more gimmicks than you can throw a stick at.

A while back, I also picked up the Amakuni Kizin toy of Genesic GaoGaiGar, and that is still the best toy of that design by quite a large margin.

So naturally, I was elated to see Hobby Japan handle the oft-overlooked Great Might Gaine.

In more recent years, we’ve had some attempts at capturing this mecha in toy form, but they have tended to be ungainly. Admittedly, these toys tried to handle all the combination aspects between Might Gaine and Might Kaiser, but the Amakuni Kizin range eschews this in favor of producing a more coherent figure.

And that’s what we have here. The proportions and styling are great, and the diecast gives the toy a good heft, as well as strengthening the joints in the process. It’s also a big toy and is suitably impressive as a result.

Apart from individually articulated fingers, which is my own personal happy place when it comes to mecha toys, you also get a variety of swords and other accessories for the main release.

There is also a separate option parts set that allows you to attach the all-important cannon to make Great Might Gaine Perfect Mode, as well as a different head and the fun pop-open drill that reveals the MG logo at its center.

The aforementioned head also has lights, with batteries included, and a tiny switch behind the neck. The Genesic GaoGaiGar also had something similar, and I am happy to see it present here, too.

You also have various fixed hands that can handle the larger swords and allow you to do your own “Brave pose” with an overtly proportioned sword.

Overall, as someone who genuinely loves Might Gaine and rates it as one of the best entries in the Brave saga, this Amakuni Kizin toy nails Great Might Gaine unlike anything else to date. From its size to a really great sculpt coupled with very fine detailing, this is much more than a simple display piece.

You can purchase both Amakuni Kizin Great Might Gaine and its Option Parts Set from AmiAmi, with the former costing $340 and the latter priced at $113.
