Although we do still have wild boars in Japan, I've never seen flying squirrels here, either in real life, or alluded to in historical imagery. I still don't think these "Japanese-style" figures look really Japanese.
They should have used more famous mythological or well-known imagery, such as "kitsune" (fox), "tanuki" (the same racoon that Heinrad tfs into), a Japanese/Chinese dragon, a bear holding a fish in its mouth (popular wood sculpture), "oni" or "tengu" (demons), the original idea they had for a crane/stalk, "kirin" (Japanese/Chinese giraffe), etc.
52 Toys did a range of Chinese/Japanese mythical robo animals, including kirin, white tiger (which looks like Tigerhawk), Genbun (tortoise/snake "chimera"), Chinese dragon, etc.
They also should have gone with more "Japanese" characters, like Windblade, Banzaitron, Bludgeon and Drift.
I think, unless there official photos look really good, I might pass on these as they look a bit "weak sauce" and not "Japanese" enough for me.
