To be honest..i am really not sure where they would go for Iron Man 3..but since Marvel are planning to make an Iron Man 4..i have decided to post my ideas for some of the main new characters and villains and Iron Man's new suit for the movie
Rumiko Fujikawa
She is originally a member of the H.A.N.D. But she later betrays the organsition and aides Tony Stark to defeat the Mandrain and the H.A.N.D Lady Bullsye..
Fing Fang Foom
While he is not the main villain..he is responsible for the events in Iron Man 4. He resurrects Aldrich Killian and gives him the Ten Magic Rings and the Mandarin Armour.
The Mandarin
Aldrich Killian comes back as The Mandarin. He is given 10 Magic rings and the Magical Armour. He leads the H.A.N.D against Iron Man. Iron Man defeats the Mandarin.
H.A.N.D
An Organsition of Ninjas which uses mystical power. Most of the H.A.N.D Members are transformed into cyborgs. The leader is Lady Bullseye
Lady Bullseye
The Leader of H.A.N.D. She almost kills Pepper and tortures Tony and cutting his arm of. She is a strong leader but also very sadistic
Iron Man 4's Main Armours
Stealth Suit
The Main Armour in Iron Man 4 will be a Red and Gold Version of The Stealth Suit
Rescue Suit
Pepper becomes Rescue in Iron Man 4. Defeats Lady Bullseye who has been turned into a Cyborg
