Emil Blonsky. The Abomination. Lived in the Christmas Train set because he was a mostly green grinchy guy that stood out on a snowy track. This dude has only two toes per foot, despite hands with five digits.
Mostly a Hulk villain. Gamma powered spy guy.
Side note, found a few bits of terrain in the container that I did in the early 2000s, held paint and shape pretty well for being shoved in a storage closet for the better part of 20 years.
