Two more monsters for the stuff on my desk collection arrived yesterday: Megalon, the giant cockroach villain from 1973's Godzilla vs. Megalon, and Namegon, the giant Martian slug from the TV series Ultra Q, the predecessor of Ultraman. The newly-released Godzilla vs. Megalon DVD arrived a couple of weeks ago, because I'm such a nerd I pre-ordered it from amazon.com. I still remember watching it on television when NBC aired it in prime time in 1977, then going to school the next day and reenacting the monster battles on the playground with my friends.
While I've never actually watched any of Ultra Q beyond some clips on YouTube, I added Namegon to my collection because, well, how can you go wrong with a giant slug?
