Wild Liger Guren is a limited edition version of Wild Liger with translucent red parts replacing the standard blue. It is a wider release version of the CoroCoro 100 limited. This version was sold at the World Hobby Fair event in Japan in early 2019.
The only differences between the WHF event version and the CoroCoro version seem to be that the CoroCoro has the shiny gold parts from the Wild Liger Awakening model.
The instructions that come with this version of the Wild Liger are the same as the initial standard release.
The Awakened Wild Liger is more of an update on the first one. With a much better gold paint, and more shiny blue and an improved motor, it is the version of the Wild Liger I would recommend getting if you just want one Wild Liger and have no interest in variants. Seriously Wild Liger variants are a rabbit hole you want to avoid.
The one I got ended up being a Korean release, despite buying it of Amazon Japan. There is virtually no difference between Korean releases and Japanese ones. Only minor thing with the Awakened Wild Liger is a booklet the Japanese release had. (Which was why I bought it of Amazon Japan, but oh well).
As of this post (August 2019) the Awakening Wild Liger, being a limited run, has become harder to find and the price for it has been going up. If you manage to find one, regardless of release, for a good deal, I highly recommend it.
The instructions that come with this version of the kit are the same that come with the standard initial release.
