Well, here's the Dark Avengers Sinister Spider-Man. I've had this custom on the shelf since the summer trying to figure out how to make a different Dark Avengers Spider-Man than just a HML Black costume Spidey. So since Mac Gargon used to the Scorpion, I'd thought he would be little more buff, so I added a little bulk and height. His upper torso can be interchanged into a mid-transformation Venom and the custom has a Mac Gargon variant head.
Dark Avengers Spider-Man was made from an HML Adam Warlock torso, HML Black Spidey arms & lower legs, ML unknown thighs, and a total sculpted head.
Mid-transformation torso was made from HML Hulk series Absorbing Man, Alt head was from a Charmed Balfazer head, Bat-man Animated Clay Face arm for the back Venom goo.
