Iron Man Armor Mark V (Earth-6531)

The Mark V Armor was Tony Stark's fifth Iron Man Armor and the first specialized armor, focusing on portability and accessibility. The suit can collapse and be concealed ala a briefcase, but when activated, the suit opens, enabling the user to take hold of it and assemble it through their body.

Capabilities
Specializing in portability and accessibility, the Mark V was designed to grant Tony Stark a portion of the benefits that the normal armor gives him no matter where he was or what situation he was in. With that in mind the Mark V was constructed to be much lighter than the previous armors. The suit is made up of a multitude of individual, miniature plates that allowed the suit to be collapsed and compacted into the unassuming form of a briefcase. When activated the briefcase can reform into the Iron Man armor within seconds.

Like previous models, the armor increased Stark's natural physical abilities to superhuman levels, granting him high levels of superhuman strength and durability. However, due to the lighter plating and gaps between the numerous plates this suit was slightly more vulnerable overall than the other models as several strikes from Whiplash, in his arc-powered harness, began to tear through and severely damage Stark's armor.

Also due to it's focus on portability, the armor lacks any of the on-board weapons of the earlier and future models, but is still equipped with weapons level repulsor gauntlets for combat as well as a standard unibeam.
