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.
