>>9509540Long story short, Retro Shocker and Retro Mysterio (the bottom two) are the better figures imo, although Mysterio is just a repaint so either is good. Doom is the same, you basically just pick whether you want spell books and magic effects over a modern head and a darker green tunic.
Personally, I prefer modern Doom, the new Retro Shocker, and I could go either way on Mysterio.
