@Abe, thanks pal!
@Spoon, thanks! The fire effects are wrist blasts from the Revoltech War Machine. They fit right over the muzzles on a number of 1/12 firearms, which is nice since you don't have to mod all of your weapons. The MS Doom throne rocks--I picked that figure up specifically for the base
Background is part of the Dracula's Castle set from the short-lived Jakks-Pacific "Van Helsing" line. I stumbled upon it on a random eBay search for "Marvel Legends Castle" in my search for HYDRA props. The paint detail is lacking but I got it for a good deal at $20 shipped. Might repaint it.
LOL at the Zemo "limp neck." My intent was actually to have him eyeing the grenade at his feet. I customized mine with a Revoltech joint at the neck to fix said crappy neck joint and also modded a LOTR sword and sheath. This one can look all kinds of ways without going all narcoleptic!
It's a shame the stock figure has so many flaws--the sculpt and paint detail are very good.
