Scarecrow - only available in the "Scarecrow and the Spider" multi-pack
Will O' the Wisp - easy custom to make, he was a Ka-Zar head on a Molten Man body (Which BTW suffered from the "Gold Plastic Syndrome" common to many Generation 1 Transformers and thus was very brittle)
Swarm - from Spider-Man Spider Force series, which was a cool line in that it had 3 Spidey villains, 1 Female (Wasp) and only 1 Spidey variant
Man-Wolf - aka John Jameson. This was a Savage Land Wolverine body, head from X-Men 2099 Halloween Jack werewolf mask, kneadatite costume details.
