Also, I HATE to do this, but I have almost NO knowledge of accurate or good stylization figures of flying Hedorah. X-plus would be too big (IF they made one, I think they did?), and something smaller than the 2006 Bandai Hedorah. Any suggestions/pictures would be appreciated!
There are a couple of Marmit flying Hedoras in this photo.
Marmit's Vinyl Paradise Hedoras. These are available in more accurate grey colors, but I picked up the pink ones for the awesomeness factor.
And here's the Marmit Para Baby set.
