If "Iron Man 4" begins shooting today, who will be the possible villains on the storyline? Apparently, the huge success of the Marvel Comic hit has created rumors that there will eventually be an "Iron Man 4."

According to Movie Pilot, if indeed the time to create the fourth installment of the movie is now, several villains are lining up to play the part. In fact, around five Marvel characters are in line to take on the role, including The "Real" Mandarin, Crimson Dynamo, Titanium Man, Blizzard and Living Lazer.

To cap it off, the possible villains have their own unique way of contradicting Iron Man and a possible characteristic to be named as the Iron Man's nemesis.

One of the potential villains, The "Real" Mandarin, is the leader of the terrorist group that held Tony Stark and turned him to Iron Man. After Iron Man destroyed their hopes to acquire the most deadly weapons, also manufactured by the Stark Corp, the possibility of Mandarin taking revenge is very high.

Crimson Dynamo is also a good choice, but his role on "Iron Man 2" ended when he died as an old man. Nevertheless, a twisted storyline could also bring back the Dynamo.

Titanium Man is the creation of the Soviet Union, thinking that they do not want the U.S. to be superior after introducing Iron Man. Titanium Man, also known as Boris Bullski, is made of titanium, which is clearly a more sturdy and durable material as that of an iron. The Bullski is also designed to be much larger than Iron Man, although at the time wherein their fight was clearly a no-win situation for Stark, the Iron Man still managed to win.

Blizzard is another character whose departure from Agents of SHIELD do not clearly state if he died in the bottom of the river or not, citing that his body has never been found. Such abyss concept can only mean one thing — a possible return of a character after it was profoundly exited from a story.

Finally, the Living Lazer, who has the ability to gain and control power, can also be declared as one of Iron Man's antagonists.

Meanwhile, the comic book "Invincible Iron Man" is set to be released this December, Master Herald reports. Should the "Iron Man 4" pushes through, the possibility of taking the story plot of the new book could be the next concept of the blockbuster movie.
