The Black Knight was made with the torso, head, and cape of a ML Dr. Doom. The arms and legs of a ML Silver Surfer. The Hands from a Spidey Classic Daredevil and the bottom legs are from a Spiderman. His crotch is from a Hobgoblin toy from Spidey Classics Line. The gloves and boots were sculpted using Kneadite as was the helmet. The Sword is from a Lord of the rings toy and the hover bike is on loan from Hawkeye.

Wonder Man is a ML Magneto from the waist down with his waist being modified to take a ML Thor torso. His arms are also that of Thor’s. His head and neck are from a modified ML Magneto. I had taken better pics recently since I modified him some more but I can’t find them now.

The Yellow Jacket & Wasp two-pack
YJ was a silver surfer. I cut into the surfer and installed the wings which were the knee guards from a ML Thor (dremelled into shape). I then sculpted around the wings so that there were no gaps, his ear pieces were also sculpted. The gloves and boots are from a FF movie series two Mr. Fantastic.
 
The Wasp was a Microman Bat Girl. Shaved off the ears and gave her some hair and got her wings from a Marvel Stinger

Hawkeye is plain Hawk with some modifications. His hands were swapped out with a black spider mans so he could hold his bow and arrows. His top legs are Mr. Fantastic with his knees on down being from a series 1 Captain America. Then he was repainted so all his colors matched.
