[Baltan II]

The choices aren't all that odd, it's Bandai selecting five of the most popular and well-known Godzilla monsters in the West, using the better-known Heisei versions for the applicable monsters, then producing them with Godzilla himself as chibi figures. There's no reason they have to be "from" something considering Bandai America's varying choices of 6" vinyl sculpts, the entirely made-up Fusion variants, or the Tokyo Vinyl figures.
