1. Fin Fang Foom
Im not a huge fan of the character in the comics, but an on-screen version of Fin Fang Foom could end up looking fantastic if its done right and he'd make a really great villain in Iron Man 4. The Iron Man movies have been a great success, with number 3 smashing the box office proceeds of those before it, but never has Stark had to go up against such a monstrous foe on his own. The sluggish Leviathans he faced alongside his Avengers team-mates were big and caused a lot of collateral damage, but they didnt have much else going for them. Foom however, who was first introduced in 1961 and is therefore a long-standing Iron Man foe, is a giant intellectual dragon with regenerative abilities and the ability to fire a combustible acid mist from his mouth and would be a different prospect altogether. And seeing Foom going up against Stark on screen would surely be a sight to behold. He has links to the Mandarin, which could be explored as well, and would make for an interesting movie twist. So, mainly for the potentially outstanding visuals, Fin Fang Foom would be a great addition to the MCU and would be wonderful to see in Iron Man 4.
Do you agree that the villains in this list would be cool to see in Iron Man 4? Which other Iron Man rogues would you want to make an big screen appearance? Let us know in the comments box below! And please feel free to follow me on Twitter.
