Figured I'd draw this up, to help give us some real-world scale.
--dimensions are close, depending on your source--
IronMan is Twice the height of a Fraggle.
Hulkbuster is Twice the Height of IronMan.
Gorg is 4 times the Height of Hulkbuster.
Stay Puft Marshmallow Man is 3 times the height of Gorg.
Eva is 1.25 times the height of Marshmallow Man.
Scales are based off of Travelling Matt (a Fraggle in Fraggle Rock).
When he explores the World, he interacts with Humans, which gives you a Scale for them.
And if a Fraggle fits in the Palm of a Gorgs Hand, that means Gorgs are WAY BIGGER than IronMan.
Not sure the Hulkbuster could take them out, if they decided to attack us.
I wonder what the scale for IronMan is, compared to the Tripods from War of the Worlds.
