Iron Man Armor: Mark VI

The Mark VI armor is a replacement for Mark IV after Tony Stark realized the Palladium in the Arc Reactor was poisoning his body. This suit uses the new element: Vibranium  and the chest piece is now triangular.

History
Tony created the vibranium from his father's research and JARVIS informed him that it would be a suitable replacement for the palladium in the Arc Reactor. Tony constructed the Mark VI to withstand the force of the new arc reactor which the Mark IV could not. Using it he flew to New York to confront Hammer, find Vanko and reclaim the Mark II from Rhodes. Upon arrival he discovered Vanko built drones for Hammer and the Mark II was weaponized and re-named "War Machine". Regardless he attempted to have Rhodes help him in his mission. At that moment Vanko took control of War Machine and the drones. Pushed to its limits the Mark VI destroyed many drones and fought the War Machine in a fist fight until Natasha rebooted the Mark II's software. The two later fought the remaining drones. They later engaged Whiplash in a final confrontation. When all drones were set to self-destruct. Tony used the suit to save Pepper. The Mark VI was heavily damaged by the confrontation.

The Mark VI was eventually repaired. When Stark Tower was under construction Tony installed a special system in the penthouse so the Mark VI could be removed, assembled and stored. Tony implied the Mark VI was used in the tower's construction saying he did the "heavy lifting". When Stark Tower was complete Tony used the Mark VI to disconnect the tower from New York's power grid. It demonstrated under water capabilities as well as two lights in its helmet.

Tony traveled to Germany with it and used it when battling Thor. While on the Helicarrier the Mark VI was kept in S.H.I.E.L.D.'s armory. It demonstrated that it was the first suit that could be remotely activated. Using it, Tony attempted to manually replace the damaged turbines on the Helicarrier. While succesful, Tony did not exit the fan in time. This caused severe damage to Mark VI. Upon discovering Loki's location Stark repaired the armor and used it to fly to Stark Tower. On arrival it was clear the Mark VI was not combat worthy in its damaged state. It was retired and Tony later donned the Mark VII to fend off Loki's army.

It was eventually repaired. When Stark's mansion was attacked, being one of the "classics" (I-VII) it self-destructed to protect its technology from the Mandarin.

Abilities
The Mark VI is the most powerful model built, just before the introduction of the Mark VII. Like all previous models, the suit increased the physical abilities of the wearer, giving Stark superhuman strength, durability and reflexes. The most improved feature is the new Vibranium-powered Arc Reactor that gives the suit more power than ever before, superior in every way over the previous generation Palladium-powered Arc Reactor. It has improved flight and weapons systems. The repulsors are capable of more sustained charge and the missile weapon systems inside the suit is improved. It even includes the mini-guns from the Mark III. The newest feature is the palladium powered laser system that when used can cut through Hammer drones with ease. Although it can be used for one time only before having to eject the burnt palladium. Overall, the suit is the most powerful model by Stark thus far as it has enabled him to tear through Hammer Drones, battle two Asgardian gods, and survive tremendous amounts of damage before it was retired.
