I'm a fan of the old Marvel Secret Wars toys. They had simple sculpts and paint apps that rubbed off easily, but in the 80's they were all we had and pretty awesome. I picked up Baron Zemo loose at a local comic shop a couple months back. He almost looks like Spider-Man in a weird outfit. He has the red mask and torso with lines on them. He's also wearing a pink singlet with yellow gloves and boots.
Baron Zemo was released in 1984 as part of the Secret Wars toys. He came with a yellow belt, black blaster, silver shield, and inserts for the shield. I unfortunately don't have any of his accessories, but since his paint was so clean I had to grab him. Other than that I'm not real familiar with the character.
