First I will be showing his "All new all different Marvel armor" (model 52). While its limits are unknown it seemingly possesses the ability to shape shift into any form Tony wants (similar to the Bleeding Edge armor) it does not appear to have the same limitation of mass. These videos we're created by Comicisland. All credit to him. At 1:10 we see Iron Mans new armor is capable of shapeshifting into a Hulk buster configuration without additional mass being added. In comparison to the Endo-sym armor, which required extra mass for such a transformation. At 4:45 we see that the armor is capable of turning invisible while keeping Tony visible.
