Alternative suits built by Tony stark

War machine 

The JRXL-1000 Variable Threat Response Battle Suit or War Machine is a solar charged carbon-composite-based external plating armor which provided its user with superhuman-level strength and durability as well as utilizing laser guided munitions.

Iron Patriot

Rhodey has his War Machine armor upgraded by A.I.M. and painted in a red, silver and blue patriotic design. Iron Patriot then becomes the Army's top soldier to dangerous fights overseas.

The armor has the same systems seen in its two predecessor models, the Mark II - computer system with extensive sensor systems, Global Positioning System, in-armor communicator\phone, repulsors installed on each hand, Thruster Boots - and War Machine - a shoulder-mounted gatling gun and and various concealed weaponry. The Iron Patriot was shown to be vulnerable to extreme heat. 

Hulkbuster 

Iron Man used this armor to battle the Hulk which was a very brutal fight. The armor's magno-hydraulic pseudo-musculature provided greatly enhanced strength rated at 175 tons. Sensors were adapted to focus on detecting gamma radiation. It had impact-resistant carbon composite plating and an anchoring system.

Rockets are used to boost the armor's punches. An injector was loaded with anti-gamma radiation nanites.

Thorbuster 

Its design was based upon Thor's enemy, the Destroyer. The armor was powered by an Asgardian mystical element. Everything from flight to life support utilized the magical energy. A facemask could be lowered for additional protection. If need be the wearer could eject and use a normal Iron Man armor.

Experimental "Type X" repulsors could be used to boost the armor's punches in addition to the standard blast. The uni-beam fired large bursts of energy. Also impervious to any kinds of harm except, oddly enough, Thor.


The Asgardian Crystal empowers the armor and allows it to absorb and manipulate Asgardian energies effectively giving him Odin Force.

Asgardian Destroyer

Taking into account that Earth might face future threats from the ASGARDIANS, TONY STARK set about designing an armor to take down any invading ASGARDIANS. Using the DESTROYER's blueprints stolen from S.H.I.E.L.D',s HELICARRIER, STARK creates the ASGARDIAN DESTROYER ARMOR.

Godkiller

Rumor has it Tony Stark may find his way into space to meet the Guardians of the Galaxy.

Making its first appearance at the end of the "Believe" arc, the Godkiller armor was designed by Tony with an emphasis on space travel. The suit sports back-mounted rocket thrusters and a redesigned helmet, which looks radically different from the faceplates featured on the previous armors. The new armor also contains an A.I. named P.E.P.P.E.R., which is modeled after Pepper Potts.

HeartBreaker V.0.2 - Ultimate Iron Man

Having his armor badly damaged in his battle with the MANDARIN, TONY STARK modifies and upgrades his HEART BREAKER ARMOR into its second version. Equipped with more ARC REACTORS to increase its output and offensive capability, this is the ULTIMATE IRON MAN.
