>>8620708I have the Yamaguchi Venom. He can do a lot of fun poses, and has some good accessories (articulated tongue, faceplate, and some tendrils). He can be a bit awkward to handle though. My Venom's arms fall off frequently, and the faceplate doesn't have any traction so it'll fall off if you put him upside down.
I don't have Monster Venom, but I will at some point. From what I've seen you'll get a sturdier figure, but far less options for posing.
