the Masters of Evil!
Fixer, Moonstone, Baron Zemo, Radioactive Man, Klaw
Since this picture, Absorbing Man, and Goliath. I have started the Melter, Tiger Shark, Mr. Hyde, the Wrecker and Titana.
Since I committed to create a complete roster of Masters, a certain Mr. Busiek creates a HUGE 25 member MoE in the Thunderbolts. Thanks so much, Kurt. At least I already had Klaw, Sunstroke, Constrictor and Eel done.
