3. The Villains
Photosynthetic decagenarian snipers, psychic fetishistic KGB agents, flamenco dancing, immortal vampires - the Metal Gear Solid saga's colourful cast of villains is probably only equalled by Batman's rogues gallery and it's something fans love. If Arad decides to use one of the series' groups of villains, they could come off as ridiculous to general audiences - because they are! But Foxhound, Dead Cell and The Cobra Unit are full of such iconic characters, and it would be shame if at least some of them weren't featured. The setting and time period of the movie will largely dictate the villains, but perhaps it would be simpler if it just pitted Solid against Liquid, or Snake against Big Boss.
